Minimalist Habit Tracker with Year Grid

Offline, privacy-first habit tracking app (no account required, AES-256 encrypted). Minimal UI focused on streaks and consistency. Already proven with 65k+ downloads and $200/mo revenue. Target: people who want simple habit tracking without cloud sync concerns or complicated features.

Privacy anxiety around health apps is genuinely rising — App Store reviews for competitors like Streaks and Habitify are littered with complaints about mandatory accounts and opaque data practices, and Apple's App Privacy labels have made users more conscious of what's being collected. No single incumbent dominates the offline-only niche, though Streaks holds mindshare in the broader habit tracker space. At $500–2k/mo, the math works if you're treating this as a paid-upfront or one-time-purchase mobile app with near-zero infrastructure costs — no servers, no sync, no support burden from account issues — so margins are unusually clean for the category. The real kill risk is discoverability: the App Store is saturated with habit trackers, and without a differentiated acquisition channel beyond organic search, growth tends to plateau fast, which is probably why 65k downloads has only converted to $200/mo so far — that ratio suggests either a weak monetization hook or a free tier that's too generous.
