The problem
DietTalk needed to work for two very different users at once: patients tracking their diet and weight from their phone, and doctors supervising them and sending guidance. That is a mobile app and a clinical web tool, tied to the same patient data, and it had to ship to both app stores.
What I built
DietTalk is a doctor-supervised diet and weight management product. Patients use a Flutter mobile app to track diet and weight; doctors use a web portal to supervise and send guidance, with AI insights on top. It is live on the App Store and Google Play.
I built the mobile app in Flutter for both iOS and Android, the doctor-facing web portal, and the backend on PostgreSQL and Supabase that connects them.
The hard parts
One codebase, two stores
One Flutter codebase had to ship cleanly to both iOS and Android and pass both stores, while the doctor portal stayed tied to the same patient records the app writes to.
Reading documents instead of re-typing them
Instead of making people re-type everything, the product reads lab results and captures patient details straight off documents, then uses that to auto-fill the clinical workflow. It removes a pile of manual data entry, and it means the data doctors act on comes from the source. Health data is handled securely throughout.
Where it is now
DietTalk is live on the App Store and Google Play, in real use by patients and the doctors supervising them.
