About

Cronnote

Features
Read full description

Cronnote is the reminder app for the recurring obligations that actually matter — rent you collect, bills you pay, doctor appointments, and pet medications. Unlike a to-do list, every item is one CHAIN with its whole history: each occurrence keeps its own date, note, and photos, so you can trust it a year later. WHY CRONNOTE IS DIFFERENT • Never goes silent — overdue items nag once every morning until you act, with a bold "3 days late" on the card. No more single reminders you miss and forget. • One item = the whole story — snap the paper appointment slip or the payment slip onto the visit it belongs to. Photos and notes per occurrence, past and upcoming, all editable later. • Counts periods and days, never amounts — "2 periods owed · 34 days late", grace periods, mark-paid one period at a time. A reminder, not accounting. • Repeats from when you actually did it — pet meds every 2 months counted from the real dose date, the repeat-after-completion that other apps refuse to ship. • Lives in the real world — mirror your dates into Calendar, see busy days when picking the next date, optional email reminders BUILT FOR Owner-operators of a few real obligations — landlords with a handful of units, pet owners on scheduled meds, anyone tracking recurring appointments. Fast two-tap date entry, large readable dates, one-handed. ALSO INSIDE • Two simple ways to add: pick each date yourself, or set a repeating rhythm. • Notes with tappable checklists + global search. • Passcode / Face ID lock. • Export your data anytime — JSON (restorable), CSV (for your records), or calendar (.ics). • English and Thai, with Thai Buddhist-era dates. Your data is yours: sign in, sync across your devices, delete everything anytime. No ads. Reminders only — never accounting.
