E‑commerce platforms
- Problem

Mobile app · Android and iOS
Dietabis
- Problem
- People who cook with a thermo cooker want to eat to a specific calorie target, but counting calories and macros after every recipe change takes time.
- Solution
- Ready‑made meal plans in several calorie levels. Each dish shows changes “in the pot” and additions “on the plate” with calculated calories and macros, meal swaps within the plan and a one‑off purchase with no account.

- Result
- The app is launching in Poland; release on Google Play and the App Store is being prepared.
