For companies investing in education app development, two fast-growing segments stand out: mobile learning and learning management systems (LMS).

Mobile-first solutions are leading the adoption, especially among Gen Z and adult learners who usually need to balance study with work or caregiving. The Business Research company notes that the mobile learning market was valued at USD 86.4 billion in 2024 and is expected to exceed USD 110.4 billion by 2025, with long-term projections indicating USD 340.9 billion by 2029. 

At the same time, platforms are scaling up through deeper integration with institutional ecosystems. The LMS market, foundational for schools, universities, and enterprise learning, is projected to grow from USD 28.6 billion in 2025 to USD 70.8 billion by 2030, expanding at nearly 20% CAGR, according to Grand View Research.

These shifts highlight why offering content alone is no longer enough. If you want to know how to create a learning app that meets today’s expectations, your product must support personalization, analytics, and adaptability at scale.

EdTech Trends to Watch

To build an EdTech platform that stands out, it’s essential to understand the trends reshaping how users learn and what they expect from modern platforms.

1. AI-Powered Personalization

Learner behavior is showing massive gains through the use of adaptive learning tools. For example, personalized recommendation systems can boost content consumption by 60% and overall app usage by 14%.

Across multiple studies, students using AI-powered platforms achieved up to 19% higher test scores and mastered complex topics 31% faster.

2. Immersive Learning (AR/VR)

According to SNS Insider, the AR/VR in education market is booming – expected to grow from roughly USD 4.7 billion in 2024 to over USD 28 billion by 2032, with a CAGR of more than 25%. These statistics show that immersive experiences are increasingly expected in a customized education app, especially in STEM, vocational training, and simulations.

3. Gamification That Motivates 

Gamification remains one of the most effective tools for boosting student engagement. According to academic research, gamified environments intrinsically support motivation, encourage active learning, and foster positive emotional experiences. 

Points, challenges, and progression systems promote a sense of achievement and sustained attention, primarily when integrated with adaptive content and storytelling. 

4. Parent & Teacher Empowerment

Even as digital learning continues to grow increasingly complex, parents and teachers play a critical role in guiding students – especially in hybrid and K-12 environments. As part of the modernization of digital learning solutions, platforms are evolving to better support not only learners, but also the adults involved in their education.

Features that support goal tracking, assignment visibility, and two-way feedback help build trust between platforms and the adults who shape a child’s learning environment. The European Commission’s Digital Education Action Plan reinforces this shift, calling for custom EdTech apps that empower educators and caregivers alongside learners.

5. Mobile Learning with Purpose

A 2023 study found that students using mobile-based learning tools reported higher satisfaction, more positive attitudes toward learning, and an increased sense of autonomy and control over the learning process. These effects are strongest when mobile content is designed intentionally to be short, focused, interactive, and aligned with learning goals.

6. Equity‑Driven Innovation

Adaptive interfaces, voice technology, and multimodal content are expanding access to educational software, especially for learners with disabilities or non-traditional needs. 

A recent peer-reviewed study on adaptive accessibility interfaces confirmed that personalized accessibility tools improve engagement, comprehension, and retention across diverse learner populations. 

At a policy level, the OECD has identified AI-enabled equity as both a massive opportunity and a design risk, stressing the importance of responsible implementation that avoids bias and exclusion.

7. AI for Educator Workflows

AI is increasingly viewed as a tool to reduce educator overload. A recent Gallup/Walton Family Foundation survey revealed that 60% of U.S. K–12 teachers used AI tools in 2024. 

Other studies confirm these gains, noting that teachers report faster feedback cycles and greater ability to individualize content without sacrificing prep time, according to MIT Sloan EdTech.

These benefits have made AI-driven features a top priority in EdTech app development, particularly for products targeting classroom efficiency and personalized instruction.

Cons of Educational Apps

A single EdTech application can open up incredible possibilities – but it’s not always smooth sailing. Here’s what to keep in mind as you plan, build, and scale your product.

Loss of Human Contact

Fully digital platforms can never replicate the nuance of live mentorship or classroom dynamics. Social isolation remains a concern, particularly for younger learners.

Data Security and Trust

A custom EdTech app often collects sensitive data, including academic records, personal identifiers, and even behavioral analytics. Strong encryption and transparent data policies are non-negotiable in today’s day and age.

AI-Specific Risks

Poorly implemented AI can generate misleading or biased content. Hallucinations, outdated training data, or one-size-fits-all logic can compromise both the quality of learning and institutional credibility.

Hardware and Connectivity Gaps

In regions with limited access to quality devices or internet connectivity, learning experiences remain uneven across different groups of users. Even within developed countries, battery drain, app size, and platform compatibility can impact engagement.

Teacher Adaptation Curve

Introducing EdTech often requires teachers to learn new tools, adjust their instruction styles, and manage hybrid workflows on top of their existing responsibilities.

Every product comes with trade-offs, but the right format can set your idea up for success. Below are the most popular areas to explore when you are planning to make a study app, based on real learner needs and market trends.

Types of Educational Apps with Examples

Understanding the core use case behind your app helps define what users expect and how to prioritize features. Below are six distinct categories that dominate the EdTech space.

1. Online Course Platforms

Course-based apps deliver structured learning experiences that combine video, quizzes, and progress tracking. Users often expect course certification, learner dashboards, and mobile optimization. 

Examples: Coursera and Skillshare.

2. Memory & Practice Apps

Popular among language learners and exam takers, these apps rely on spaced out repetition and active recall tests to support long-term retention, often making use of flashcards, custom decks, and visual mnemonics. Strong UX, offline functionality, and performance analytics define this category.

Examples: Brainscape and Anki.

3. Exam Preparation Tools

Focused on standardized or competitive tests, these apps help learners manage revision, simulate real testing environments, and analyze performance. Timers, question banks, adaptive difficulty, and instant feedback form the core set of features. 

AI can further refine recommendations and highlight knowledge gaps, which is essential if you plan to create an education app that supports meaningful exam preparation.

Examples: TCYonline and Magoosh.

4. Knowledge Discovery & Daily Learning

Bite-sized, curated content creates daily learning habits across diverse subject areas. Users want to have quick access to articles, visuals, or quizzes, typically organized by interest or skill area. Personalization engines, scroll-based interfaces, and low-friction navigation are central to retention here.

Examples: DailyArt and Flipboard.

5. Early Childhood & Primary Education

Interactive learning experiences for younger audiences can combine voice guidance, game mechanics, and tactile design to support educational goals including basic math, reading, language, or creativity. The strongest apps in this category include parent-facing features and can reliably function offline.

Examples: Khan Academy Kids and Moose Math.

6. Special Education & Accessibility Solutions

This category addresses learners with disabilities, communication needs, or neurodivergence. Interfaces prioritize clarity, support augmentative and alternative communication (AAC), and often feature integration with adaptive content pathways. Teams creating educational apps for this audience benefit from thoughtful use of AI that enhances – rather than replaces – human input and support.

Examples: Proloquo2Go and Articulation Station Hive.

Educational App Monetization Strategies

Developing an educational app is only one part of the equation. Defining how it generates revenue is just as critical, particularly if your product is targeted toward long-term engagement or scale. Below are the most common and sustainable monetization models in EdTech today.

1. Freemium with Paid Add-Ons

Using ads, you can offer core functionality for free, with optional upgrades such as advanced analytics, exclusive content, or offline access. This model lowers entry barriers and encourages trial, but works best when the upgrade path is clear and value-driven.

2. Tiered Subscriptions

Subscriptions remain the most popular model for those who create educational apps. Many platforms offer multiple tiers like free, standard, and premium to accommodate different levels of access, personalization, or instructor support.

3. One-Time Purchase

Some apps employ a pay-once approach, especially when offering a comprehensive course, exam module, or offline package. A trial version can reduce hesitation before purchase.

4. Content-Based Commissioning

Platforms that host user-generated content, such as courses or tutoring, often charge a percentage per sale or enrollment. Commission models work best when creators receive clear value in return, such as tools, reach, or analytics. For businesses looking to create an app for teaching, this model supports scalability while empowering educators to monetize their expertise.

5. In-App Advertising

Using ads in your app can help subsidize free access, but only when handled carefully. For apps targeting children or students, you’ll need to ensure compliance with COPPA and other relevant policies. Contextual ads and user-controlled preferences further improve user retention.

Must-Have & Advanced Features for Educational Apps

Here you’ll find a fundamental list of features to develop an educational app. Basic functionality refers to your MVP development, while a combination of advanced features creates a unique portrait of your application.

Basic Features

1. Sign up: It is the very beginning of the user journey, so you should make it as simple as possible. It all starts with an email and a password, plus signing up using social media platforms like Facebook, Google, Apple, and others.
2. User profile (dashboard): It’s one section where users can add more details to their profile (age, gender, photo, etc.), review courses they’ve created or taken part in, check their studying plans, grades, and much more.
3. Search: Make sure users can easily locate a specific subject or topic. Strong search functionality, including filters and clear categorization, is essential for anyone exploring how to make a learning app that will scale well as you add more content.
4. Course (details and creation): The course creation process should be intuitive and provide educators with guidance on what to include in the description. The best-case scenario is to have a course template that teachers can start with and then modify at their discretion – for example, by adding or removing certain blocks, videos, visuals, or customizing the background color.

As a result, when future students visit this page, they should have no trouble clearly understanding its goals, tasks, program, and outcomes. After that, help the user confirm their choice by including “Payment,” “Start a trial period,” or “Start a course” buttons. 

5. Payments: Users expect payments to be fast, understandable, and secure. To ensure that, add standard payment options like PayPal, or Visa, or MasterCard. 
6. Learning dashboards: After a student chooses a course, a menu displays the list of lessons, their topics, upcoming assignments, and given grades. In other words, the whole educational process is laid out clearly from the start.

On the teacher’s side, a dashboard displays the participant list, individual progress, and class statistics. Teachers also need access to completed tests and assign grades directly from the dashboard. These features are essential to customizing EdTech apps for classroom environments that require both structure and adaptability.

For an online learning platform built for children, we created individual progress views for students, teachers, and parents, and adapted each of them to the user’s role, language, and device.

7. Test builders: Provide tutors with multiple test options and ensure the navigation process is intuitive and straightforward. It should be clear how to change the test’s type, add visuals to a question, and review changes before publishing.

In an automated assessment platform, the test builder supports multiple formats, randomized questions, and real-time scoring, all designed for high-volume use by upwards of 30,000 students. Teachers accessed completed results directly from their dashboards for faster evaluation and analysis.

8. Push notifications: Students prefer to have the ability to stay informed – or not – about their grades and course updates, while teachers want timely alerts about new enrollments and completed assignments. If you plan to create your own educational app, customizable notification settings are a simple but powerful way to boost engagement on both sides.

Advanced Features

1. In-app messaging: By providing a chat feature, you can simplify the educational process and make your app the only instrument that students need for an effective online learning experience. If you do everything just right, course participants won’t have to go outside your app and use third-party messengers to consult on issues that emerge.
2. Comments and forum: It’s better to discuss course tasks right in the app, as it puts students and teachers on the same page and saves lots of time for both parties.
3. AI Voice commands: You can make the app’s navigation easier for visually impaired users by adding the voice command feature. 
4. Video streaming: Webinars are becoming more popular, as they help bridge the gap with students sometimes hundreds of miles away. It’s no longer a challenge to study at the best universities using only a laptop, which makes video streaming one of the most in-demand functionalities when you develop an educational app.
5. Offline mode (lesson downloading): This feature is especially significant for students living in areas with limited internet access. By downloading a lesson once, a student gets information in full and won’t be distracted by a lagging video.

The kids’ platform that CHI Software worked on included offline functionality on both web and mobile, allowing younger users to stay engaged, even when they have an unstable internet connection – a critical feature in family-based usage environments.

6. AR/VR experience: Extended reality creates immersive worlds that students want to explore and learn from. There is no other way to create the most realistic learning experience and examine the studied objects from multiple angles.

When building an educational app, it’s not only about features – scalability and adaptability matter, especially when moving from web-based platforms to mobile-first solutions. We recently completed a language learning platform mobile migration, helping our client convert their web solution into iOS and Android apps. This case shows how migration can unlock new markets and audiences for EdTech businesses.

Real-World Stack Examples

For one learning platform specifically designed for children, our team utilized React, Redux, and Firebase to power a unified web and mobile experience, with offline access and multi-role interfaces built in React Native.

Another example was a chatbot for educational institutions that we developed to streamline communication and support for students and staff. Built with Node.js, Express, and Dialogflow, and integrated into the client’s existing LMS, the chatbot can perform routine administrative tasks, provide instant answers to queries, and support multiple languages. 

For an automated assessment platform, we implemented a stack combining Python, FastAPI, and PostgreSQL to deliver scalable testing, AI-enabled scoring, and LMS integration used by thousands of students in multilingual environments.

How to Create an Educational App in 5 Steps?

Before writing a single line of code, it’s wisest to take time to shape a product that solves a real need for real users. Here’s how we typically approach the process at CHI Software.

1. Define the Core Purpose

We start by identifying a specific educational gap your app will address. Is it exam prep for high schoolers? Language immersion for kids? Upskilling for professionals?

In our early-stage workshops, we often help clients reframe broad ideas into focused user goals, which is a critical first step in understanding how to develop an educational app that delivers real value. That clarity informs every design and tech decision that we will make ahead.

2. Research Your Audience & Competitors

We conduct user interviews, research the target market’s behavioral patterns, and audit similar platforms to uncover friction points and missed opportunities. For school-based apps, this process often extends into classroom settings, observing how teachers interact with students and how tools fit (or fail to fit) into real-life workflows.

3. Prototype and Test Early

We aim to test interactive prototypes not only with users, but also with stakeholders, including educators, admins, and parents. This approach helps to spot misalignment between intentions and expectations.

4. Build with Scale in Mind

We always prioritize core functionality that drives adoption and engagement. Our teams use agile sprints to build modular architectures and align backend logic with future AI expansion from the start.

Also, we deliver most MVPs with a clear roadmap for adding advanced features such as adaptive feedback, dashboards, or multilingual support, without needing to rebuild the foundation.

5. Prepare for Launch and Beyond

Our delivery phase includes infrastructure setup, deployment strategy, QA automation, and observability. We also prepare fallback methods for content delivery such as offline sync and partial caching so that an app can still function even when internet connectivity is unreliable, which is a common issue in family-oriented or rural learning apps. 

If you want to make an educational app that performs well in these conditions, such safeguards are essential. After go-live, we stay close to user data and refine features based on what learners, teachers, and admins actually do.

Bonus Tips Before Starting Educational App Development

Here are a few more insights we always share with our clients based on what’s helped our teams build stronger and leaner products:

Keep It Simple (Especially at Launch)

Trendy features are tempting, but if you want to develop an educational app that truly resonates, your early users will really only care about one thing: does the app work for their goals? Clear flows, clean content, and minimal cognitive load will do more for retention than any superficial “AI-powered” label.

Map the User Journey Early

Before diving into design, it’s a good idea to map out how you expect that each user will navigate the app: where they start, what they aim to achieve, and where potential friction might arise. Whether you aim to create your own educational app or scale up an existing platform, a clear journey map helps reveal UI gaps before they become real usability and retention issues.

Let Real Feedback Shape Your Roadmap

Some of your favorite features may not land well with users, and that’s a good thing. Criticism is direction! Prioritize feedback from your most engaged users and let real behavior guide your iterations. Such adaptability is crucial in EdTech app development, where audience needs can vary widely across age groups and learning styles.

Build for Change, Not Perfection

Markets shift, expectations evolve, and so will your app. Architect your backend to be modular and versionable, especially if you plan to introduce AI later. A flexible foundation will save you time and budget down the road.
