Tappy Paint turns your iPhone or iPad into a coloring book: 1,100+ pages, tap-to-fill, plus brush and crayon for freehand. No ads, no sign-up, no tracking, and it works fully offline. Free to start; a one-time purchase unlocks everything. No subscription.
Chroma is a period tracker that keeps health data and forecasts on your device — no account, no company servers, no ads, no third-party tracking. Forecasts start from a single period entry, show what data they're based on, and switch to a range when your cycle is irregular. Log flow, symptoms, mood, sleep, pain, BBT, weight, and tests — the same forecast drives Today, Calendar, Insights, reminders, and widgets. Export CSV or a doctor-ready PDF. PRO is a one-time purchase, not a subscription.
