The challenge

App instability

The app was prone to frequent crashes and bugs that disrupted the user experience.

Missing key functionalities

Essential features that would enhance user experience were not yet implemented.

Content security on Android

  • Android's open file system posed a risk, making it easy for users to access and share sensitive educational content.
  • Multimedia files, including video and audio lectures, were easily accessible with basic file browsing tools.
  • The client required a solution to protect these assets while ensuring smooth access for legitimate users.
We haven't just been training health coaches for 25 years. We created health coaching. Integrated nutrition.

The solution

With the goal of empowering individuals through holistic health education, the app supports students from enrollment through graduation and beyond, delivering both online and offline content across iOS and Android platforms. Montrose’s involvement spanned several critical upgrades and bug fixes to ensure the app’s stability, security, and user experience.

Bug fixes and feature enhancements

Bug fixes and feature enhancements

  • Fixed numerous bugs, improving the overall stability and functionality of the app.
  • Added new features that were essential for creating a better learning experience for users.
Custom encryption for Android

Custom encryption for Android

  • Developed a fully custom encryption algorithm to protect multimedia assets on Android devices.
  • The encryption targeted only 128 bytes of the file headers, making files unusable outside the app.
  • Ensured the encryption and decryption processes were fast and seamless, even for large files.
  • Integrated the encryption process during the file download and decryption during playback, preventing unauthorized copying or sharing.
Security testing

Security testing

  • Thoroughly tested the encryption algorithm to ensure that files could not be recovered or played outside the app, even with recovery software.

Key functionalities

Offline content access

Enabled users to download and access multimedia content (videos, audios, PDFs) for offline use, allowing learning without an internet connection.

Content synchronization across devices

Empowered synchronization across multiple devices, allowing students to start a course on one device and continue seamlessly on another.

Improved search and filter options

Added advanced search and filtering capabilities so users can easily find specific lectures, topics, or materials within their courses.

Partnership goal

Develop an intuitive iOS application that enables users to easily compose and send handwritten notes digitally, enhancing personal communication through the convenience of technology.

Before

The Learn IIN app was struggling with bugs and instability, particularly on the Android platform. Users faced frequent disruptions, and there were serious concerns about the security of educational content. The app also lacked several important functionalities needed for a smooth learning experience.

After

The app became far more stable and user-friendly, with significantly enhanced security. The encryption algorithm effectively prevented unauthorized access to sensitive educational materials, ensuring that the content remained secure on Android devices. The added functionalities and bug fixes provided a much-improved user experience, allowing students to access their learning materials seamlessly, both online and offline. Montrose’s contributions not only stabilized the app but also extended its capabilities, ensuring that it could continue supporting IIN’s mission of transforming health and wellness education globally.
