Worth knowing
Aida Reminder
- It is for iPhone and iPad only; the vendor lists no Android, Mac or web version of this app.
- The free version is limited to 1 hourly, daily and weekly reminder until the Full Version is bought.
- Notifications are local to the device; the vendor describes backup and restore, not live sync, for moving reminders between devices.
- The same developer sells a similar but separate app named Reminders, which has its own download and in-app purchase.
COL Reminder
- It is an Android app only; the web page just sends reminders to the phone app and needs both the app and a subscription.
- The developer states that it is a reminder app and should not be confused with a to-do list.
- Location-based reminders, the active-reminders widget, the full repeat options and priorities are unlocked only by a donation.
- The site publishes no prices for donations or the web subscription; Google Play shows only a range of $0.99 to $19.99 per item.
Key features
Aida Reminder
- Recurring reminders
- Reminders repeat every set number of hours, days, weeks, months or years, on chosen weekdays, on dates such as the 15th or the third Monday, or at specific times of day.
- Voice and music reminders
- A reminder can play a recording of the user's own voice or a song picked from the music library at the scheduled time. There are also 45 built-in alarm sounds.
- Auto-Snooze and Pre-Alarms
- Auto-Snooze repeats an alarm up to 5 times at a regular interval until it is dealt with, and Pre-Alarms send up to 5 notifications ahead of the scheduled date.
- Wake-up alarm
- One of the nine reminder categories is a wake-up alarm with a custom snooze time; reminders can also be snoozed from the notification banner or the lock screen.
- Calendar and history
- A calendar shows all reminders by month, a History tab lists past ones, and the list can be sorted by priority or by activation date.
- Images for reminders
- Each reminder can carry a photo or one of more than 120 built-in images. On iOS 26 and later, custom images can be generated with AI.
COL Reminder
- Text and phone call reminders
- A text reminder notifies at an exact time, and a call reminder notifies when a call is due and dials the number with one tap.
- Parking and birthday reminders
- A parking reminder runs a countdown for a short-term parking spot, and birthday reminders notify a few days ahead and again on the day.
- Location-based reminders
- A donation feature that triggers a reminder on entering or leaving a place, with a selectable distance range such as 50 m, 100 m or 1000 m.
- Repeat options and priorities
- Donors get six repeat types from minutely to yearly, with an end date or a set number of events, and up to four priorities with their own ringtones and vibration.
- Backup and Wear OS
- Reminders can be backed up to Google Drive automatically or to local storage, and a Wear OS app delivers notifications to a watch.
