Challenge
Meditation apps tend to sit at one of two extremes: a rigid guided programme with no room to adjust it, or a basic sound-loop player with no structure at all. Users who wanted to layer Solfeggio frequencies, binaural beats, and ambient soundscapes into their own practice had no real option built for that.
Approach
We built a customisable audio mixing experience rather than a fixed programme, with a synchronised audio engine that keeps multiple layers, frequency, binaural beat, and ambient bed, in sync with each other regardless of how a user combines them, built in FlutterFlow with Firebase handling accounts and content.
What we built
- A customisable audio mixing experience, not a fixed track list
- Solfeggio frequency layering alongside binaural wave integration
- Ambient soundscape blending on top of both
- A synchronised audio engine that keeps every layer coherent during a session, not just playing side by side
- Personalised session saving, so a user’s own mix is a starting point next time, not rebuilt from scratch

Outcome
Mindful Mantra is live on the App Store and Google Play, standing apart in a crowded category with personalised, layered sessions as its signature feature rather than a one-size-fits-all programme. The client owns the app and its accounts outright.
