Cronnote: Chain Reminders

Cronnote is a reminder app for the recurring obligations that actually matter — rent you collect, bills you pay, doctor appointments, and pet medications. Unlike a plain to-do list, every item is one CHAIN that keeps its whole history: each occurrence has its own date, note, and photos, so you can trust it a year later.

WHY CRONNOTE IS DIFFERENT

• Never goes silent — overdue reminders nag once every morning until you act, with a bold "3 days late" on the card. No single reminder you miss and forget.

• One item = the whole story — attach the paper appointment slip or the payment slip to the exact visit it belongs to. Photos and notes per occurrence, past and upcoming, editable anytime.

• 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 (advance-after-completion).

• Lives in the real world — mirror your dates into Google Calendar, see busy days when picking the next date, optional email reminders, and it works on Android and iPhone.

BUILT FOR
Owner-operators of a few real obligations — landlords with a handful of rental units, pet owners on scheduled medications, and anyone tracking recurring appointments. Fast two-tap date entry, large readable dates, one-handed use.

ALSO INSIDE
• Two simple ways to add a reminder: pick each date yourself, or set a repeating rhythm.
• Notes with tappable checklists and global search.
• Passcode / fingerprint / Face unlock.
• Export your data anytime — JSON (restorable backup), CSV (for your records), or calendar (.ics).
• English and Thai, with Thai Buddhist-era dates.

Your data is yours: sign in with Google or Apple, sync across your devices, and delete everything anytime. No ads. Reminders only — never accounting.
