When did you last do that? Sincely answers exactly that one question. Rotate the mattress, deworm the cat, test the smoke detector, call your mother-in-law – one tap logs the moment, and the app shows you plainly: "12 days ago." This is not a to-do app. No streaks, no points, no guilt. The number is the hero – not a red due date screaming at you. Green is the normal state. Red is rare and stays calm. HOW IT WORKS • Add an entry, pick an emoji, done. • One tap on "Done just now" when you did the thing. • An optional interval tells you when it's time again – without nagging. WHAT'S INSIDE • Home & Lock Screen widgets – your status at a glance. • Gentle reminders when an interval comes due (your call). • Full history per entry: average, past times, all editable. • Siri & Shortcuts: "Hey Siri, log watered the plants." • iCloud sync across all your devices. • 100% offline. No account, no tracking, no ads. SINCELY PRO (one-time, no subscription) • Unlimited entries (free: up to 5). • All widget styles for Home & Lock Screen. • Add due dates straight to your calendar. • Icon packs & alternate app icons. Pay once, keep it forever. Notifications stay free too. Promise. Sincely is for the things no calendar holds and no to-do list deserves – but that still want doing. Eventually.

Verdict
The clearest difference is in-app purchases: Bookcase! at none against Sincely's 1. Sincely's advantage is update cadence (every 5 days vs every 24 months) and iOS requirement (17.0 vs 26.5). On price, ads and device support there is nothing between them.
