Daily Audio Wellness App

Radiate is a Flutter meditation app designed to help users regulate their nervous system, shift emotional states, and build consistent self-development habits through guided audio experiences.
Created by wellness influencer Amber Lyon as part of the Modern Mind ecosystem, the product translates a personal methodology into a structured, scalable mobile experience focused on daily use and long-term engagement.
Challenge
The goal was not just to develop a meditation app, but to turn a content-driven methodology into a product that users return to daily.
Several challenges shaped the product:
• Structuring large volumes of audio content into a system that remains simple to navigate
• Ensuring uninterrupted playback across sessions and app states
• Designing for habit formation, not just one-time usage
• Creating a scalable backend without introducing unnecessary infrastructure complexity
• Allowing non-technical content management without relying on a separate CMS

The product needed to balance content depth, usability, and long-term retention.
Solution
Krootl developed Radiate as a cross-platform wellness product combining a mobile meditation experience with a custom web-based environment for content and operational management.

The application gives users access to guided meditation sessions, declarations, challenges, and personalized audio experiences designed to encourage daily engagement and long-term habit formation.

Alongside the client-facing application, we created internal tools allowing the client team to independently organize sessions, manage reflections and challenges, update product content, and continuously evolve the experience without ongoing engineering involvement.
