The Challenge
Most habit and focus apps drown users in features, gamification, and notifications. The brief was to design something that felt considered rather than assembled.
Our Solution
A React Native app with a restraint-first design system, gesture-based interactions, and an async Spring Boot API that caches daily prompts in Redis for instant delivery at any timezone.
“It's the rare productivity app that feels designed, not assembled. Every interaction has clear intent.”
