Flutter Mental Health App Development
Budget: $750 – $5,000 USD
I want to launch a calming, therapy-grade mental-health app built with Flutter for both iOS and Android and have it ready for the App Store and Google Play within a month.
Core experience
– Daily mood tracking, guided breathing exercises and an AI-powered chat coach sit at the heart of the product; they must feel smooth, visually soothing and work offline first, then sync to Firebase when a connection is available.
– Meditations and a private journaling space complete the toolkit, all wrapped in a relaxing visual theme.
Tech stack & integrations
• Flutter 3.x with sound null-safety, Cupertino and Material support for a single code-base.
• Firebase (Auth, Firestore, Cloud Functions, Analytics, Messaging).
• OpenAI API for the chat coach, with prompt / completion logic living in secure Cloud Functions.
• RevenueCat to handle subscriptions, introductory offers and cross-platform receipt validation.
• Localisation for 14 languages, including full RTL layout for Arabic; strings delivered via .arb files with fallback logic.
• In-app assets and text must be easily extendable for future languages.
Release quality bar
– The build must pass App Store TestFlight review and Google pre-launch report without warnings.
– Crash-free sessions ≥ 99 % on Firebase Crashlytics.
– All personal data stored and transmitted in compliance with GDPR / KVKK.
Deliverables
1. Clean, well-commented Flutter source in a private Git repo.
2. Firebase project with security rules, service accounts and Cloud Functions deployed.
3. RevenueCat configuration (products, paywalls, entitlements) and sample sandbox testers.
4. Localised strings and RTL-verified UI.
5. Signed release builds plus store-listing screenshots and metadata ready to upload.
6. One walkthrough call and hand-over document so I can continue future maintenance.
If this scope and timeline excite you and you’re comfortable merging AI, subscriptions and multi-language UI inside Flutter, I’m ready to move fast.
