Thinko: intelligent
brain training
Designing and engineering a high-performance cognitive training platform with 95+ games in a single Flutter codebase.
The challenge
Building a brain-training app requires extreme precision. Cognitive games demand 60fps performance, flawless touch response, and complex state management. Maintaining separate codebases for iOS and Android would have slowed down development of the 95+ games needed for a competitive product.
The solution
We selected Flutter as our core framework. By leveraging Flutter's custom painting and animation engine, we were able to build high-performance arcade and puzzle games that run identically on both iOS and Android.
For the backend, we integrated Firebase. Firestore handles real-time syncing of user progress, while Cloud Functions power the daily challenge generation and global leaderboards. Claude AI is used in the backend to dynamically adjust game difficulty based on user performance.
The results
- 95+ original games shipped in under a year.
- 99.9% crash-free sessions across both platforms.
- A seamless offline-first experience with background syncing.
