Read full description

Remember the date. Keep your peace. Forgetproof helps you manually organize bills, subscriptions, trials, warranties, return windows, renewals and other important dates. Add due and cancel-by dates, optional amounts, currencies and notes, then choose your reminder timing. Free includes five tracked items, the existing local reminder tools, and password-protected encrypted backup and restore through Files. Keep a backup somewhere accessible if your phone is lost. Forgetproof cannot recover a forgotten backup password. Restoring a backup replaces the saved items on that device after confirmation; it does not merge them or restore paid access. Purchases are restored separately through Apple. Plus removes the tracked-item limit with Monthly or Yearly subscriptions. Existing Lifetime purchase rights are retained. No bank connection, automatic subscription detection, automatic cancellation, automatic payment tracking, account or cloud sync. Dates are entered and maintained by you. Reminder alerts require notification permission and remain subject to device settings and system delivery limits.
