Mobile App Development – Audio-Guided Visualization App (React Native or Flutter)
Budget: €3,000 – €5,000 EUR
We are looking for a mobile app developer or small team to create a minimalist wellness app for iOS and Android using a single codebase such as React Native or Flutter. The app will guide users through 5-minute audio-only visualization sessions generated from their written intention. All Figma designs for mobile are already prepared.
The app will include onboarding (where the user writes their intention), a dashboard with a single "Start Session" button and a streak counter, a full-screen session player with a countdown and play/pause, and a settings page where users can edit their intention, toggle daily notifications, and switch between light and dark mode. The app should send daily reminders via push notifications.
When a user starts a session, their intention is sent to an API that generates a short script using GPT, converts it to speech using a TTS service like Google or AWS, and returns the audio file for playback. Optionally, sessions can be saved locally for offline use.
The backend can be built with Node.js or Python and should include one endpoint to handle the intention, generate the text, and return the audio. It can be hosted using lightweight cloud platforms like Firebase Functions, Railway, or Render.
Deliverables include working iOS and Android apps, source code with documentation, and test builds via TestFlight and Google Play Console. Post-launch support for bugfixes and basic adjustments should be included.
We are looking for someone with experience building mobile apps, ideally involving audio features. Familiarity with AI or TTS integration is a plus. Clear communication and an estimated timeline of 4 to 6 weeks are important.
In your proposal, please briefly explain your tech stack, timeline, total price, and links to relevant apps you’ve built.
We’re excited to work with someone who can bring this calm and focused user experience to life.
