Migrating an Educational Platform from Web to Mobile Apps

The client: a U.S.-based company working in the EdTech learning app sector. Their solution is an educational learning platform that combines entertainment with education by using movies, TV shows, and documentaries as a learning base, while interactive features help learners practice naturally during their free time.

The platform already serves both individual users and organizations worldwide, but to continue growing, the company needed a language learning platform mobile migration, so they turned to CHI Software, which was selected to deliver results.

Project background

The client already had an established web-based solution that was popular among learners; however, the growing demand for mobile access was highlighting the need for change, as many users preferred to study on smartphones rather than desktops. The need to research educational platform migration became the company’s most logical next step.

To meet the client’s ambitions and expectations, the new app had to support interactive subtitles, personal vocabulary banks, and smooth video playback — while also introducing valuable new features that mobile users are coming to expect, such as offline access, push notifications, and short study sessions.

The client selected CHI Software to lead the EdTech web-to-mobile app migration. Our team designed and developed native iOS and Android applications, making sure they combined reliable performance with a straightforward and user-friendly interface.

The overall goal was to develop a mobile-first product that would expand the client’s global reach, provide learners with greater flexibility in their study methods, and enhance the company’s standing in the competitive EdTech market.

Business needs

Mobile Presence:

The client required a strategic plan to expand into mobile-first markets. We determined that a complete EdTech platform mobile transformation was the best way to strengthen visibility and put language learning in the palm of users’ hands on their smartphones.

Consistency Across Platforms:

The process of migrating the EdTech platform to a mobile app required delivering the same depth and reliability as the web version, while adjusting features to feel natural on smaller screens.

User Acquisition:

Achieving the desired growth depended on reaching learners through their app stores. The educational software web-to-mobile transition was a means to attract users who prefer mobile apps over desktop solutions.

Learning Flexibility:

Offline access and shorter sessions were required so learners could practice while commuting, traveling, or studying between tasks.

User Engagement:

A more engaging experience was vital. Personalization, progress tracking, and gamification were key factors in keeping learners motivated – encouraging them to return regularly.

Progress Tracking: Dashboards displayed milestones, tracked vocabulary growth, and visualized achievements, helping learners stay organized and motivated.

Gamification: Quizzes, flashcards, and light animations kept the process interactive and dynamic, turning study into an engaging activity.

Podcast Section: A separate space provided access to language-focused podcasts, adding another effective way for learners to practice on the go.

Solution

Requirement Analysis

The CHI Software team began by working closely with the client to clarify their priorities. During this stage, the core features for the educational software web-to-mobile migration were defined: interactive subtitles, a personal vocabulary bank, and stable video playback. These elements became the basis for the new mobile solution.

UI/UX Design

Design efforts focused on creating a mobile-first interface to convert the educational web platform to a mobile platform successfully. The navigation needed to remain simple, with the interface adapted to different screen sizes. Accessibility standards were followed from the start because the goal was to make learning easy and intuitive on any user’s device.

App Development

To ensure stability and long-term performance, native development was chosen. The iOS and Android migration for EdTech introduced advanced video playback controls, personal vocabulary storage, and real-time translation features. Each function was optimized to provide flexibility and reliability.

Testing and Optimization

The web-to-app migration for education included thorough testing across a wide range of smartphones, from flagship models to mid-range devices, guaranteeing smooth performance for the broadest possible audience.

Deployment and Support

After successful testing, the apps were released on both the App Store and Google Play, marking the completion of the EdTech platform mobile transformation. The client then gained access to analytics for tracking user behavior, and the CHI Software team continued providing updates, fixes, and improvements after launch.

Enhancements

After launch, the app was improved with features that made learning more convenient. Offline mode was upgraded to allow users to continue studying with interactive elements. Caching was added to speed up loading, and a dark mode option was provided for comfort during evening use.
