It’s super clunky and slow to respond to movements of the map. You also can’t delete your account if you don’t want to use the app anymore. The in app behavior seems geared to force you to stay. It also collects your private health information and there’s no way for you to have them removed once you’ve given it to them. **Developer response:** hey! adam here, the solo dev. thanks for this feedback, it genuinely pushed me to make real improvements. i want to address everything directly: ✅ the vancouver default has been updated; the app no longer suggests that location on startup. ✅ performance has been significantly improved; map responsiveness and movement should feel much snappier now. ✅ account deletion is available in settings, and i've made it more visible so it's easier to find. ✅ health data: your data is only used to power the game mechanics, never sold or shared; and deleting your account removes all your data entirely. if you have any more feedback, dm me on instagram @chewylift or email info@arniifitness.io... i respond to everything myself. thanks for helping make checkin better 🙏 ### 1/5 — Clunky, Bloated, Can’t Delete Acount *2026-01-31* The app is forcing you on the map in the Vancouver Canada location, probably to make it look like a lot of people are using the app, that there’s a high concentration of people in the area.
