Our role: Mobile app development for iOS and Android
Year: 2025

Summary

MindNudge is a micro-coaching app: instead of long sessions, people exchange short voice and text messages with their coach, their “Nudger”. We built the MindNudge mobile app for iOS and Android.

Challenge

Coaching works best when it's continuous. But hour-long sessions are hard to schedule, and momentum fades in between. So MindNudge bet on asynchronous audio micro-coaching: short messages between a person and their coach, anytime and anywhere — on the tram, on a run, or at night when sleep won't come.

They first tested the method over WhatsApp and iMessage. For company pilots and further growth, though, they needed their own app: calm and human rather than yet another productivity tool, yet reliable at recording, playing and delivering messages on both iOS and Android.

Solution

Working from the Figma designs, we built MindNudge as a mobile app for iOS and Android:

One codebase for iOS and AndroidWe built the app in Flutter, so both platforms share the same features and look. The backend runs on Firebase.
Sign-up and choosing a coachPeople sign up on their own or with an invitation code from their employer. They pick their topics, “not sure yet” included, and choose a coach by profile and video intro.
Voice messages with transcriptsRecording and playing voice messages, at double speed too, with a transcript and a summary. After a coach's question, people rate how much it moved them and how long they spent on it.
Home screenThe coach one tap away and a countdown showing how much time is left to reply. People always know where they stand, and can recommend the app to others.
Design system in codeColours, typography and shadows taken from Figma, light and dark mode, and the app in both Czech and English.

MindNudge welcome screen with the heading “Aktivní ucho!” (An active ear!) and a Start button — **Welcome:** the intro screens explain why it helps to open up to another person — “an active ear”.

Topic picker in MindNudge — health, relationships, money, work and career, procrastination or “not sure yet” — **Topics:** health, relationships, career or a custom topic; “not sure yet” works too.
