DotDue

DotDue is for the things you must not forget. Photograph the shelf, the tray, the container, the batch, then mark the exact parts that matter with a color.

Every color carries its own time limit. Tap the photo where something sits, choose a color, and DotDue starts counting. Red might mean four hours, purple a month. You decide what each color means.

When a mark runs out of time, the photo comes back as a reminder: a notification carrying the picture, and an inbox of everything that is overdue or nearly due.

One photo, many deadlines
A single photo of a fridge shelf can hold a "use today" mark on one container and "good for a month" on another. Only the one that has actually lapsed will interrupt you.

Nothing to keep running
There is no background job to babysit and nothing to wake up. Whether a mark is overdue is worked out from the clock every time you look, so a phone that was switched off for a week shows the correct overdue list the moment it is opened.

Counts down in your language
Available in English, 简体中文, 繁體中文, Español, Français, Deutsch, 日本語, 한국어, Português (Brasil) and Русский. Durations, dates and countdowns are written the way your language writes them.

Made for marking up
- Marks land exactly where you tapped, not just somewhere on the photo
- Give each color a name and a time limit of your own
- Add a note to a mark when the color alone is not enough
- Snooze a reminder by 15 minutes, an hour, four hours, until tomorrow, or next week
- Acknowledge a mark to clear it for good
- Everything stays on your device: no account, no sign-in, nothing uploaded

Good to know
DotDue is free and supported by ads.
Reminders are a convenience, not a safety system. Please do not rely on them where a missed deadline could cause harm.
