Hi HN, I've been working on a solution to a problem I personally struggled with—maintaining focus in our hyper-connected digital environment. Rather than simply blocking apps or showing stats, I wanted to create something that would make the journey toward better digital habits engaging and rewarding. EvoCat is the result: a digital companion that evolves visually as you build better focus habits. Think of it as a Tamagotchi with a purpose. Your cat grows stronger when you successfully complete focus sessions, and it provides increasingly sophisticated interventions (like guided breathing exercises) when you're tempted by distractions. Technical highlights:

Uses on-device activity monitoring without sending data to servers Implements progressive friction that adapts to your usage patterns Gamifies focus with visual pet evolution that provides tangible progress markers Combines scheduled focus sessions with real-time intervention

I'd love feedback from the HN community on both the concept and implementation. Has anyone else tried merging digital wellbeing with virtual pets? What other interaction patterns might make focus more engaging? You can try it at [https://evocat.app]. There's a free tier to get started.
