CannotWait review: how many days until, at a glance
CannotWait counts the days to the moments you are waiting for and the days since the ones that already happened. You add an event, pick a date and see the count in the app, in a widget on your Home Screen or Lock Screen, or by asking Siri. The App Store lists it as free with no in-app purchases. We describe it by what the App Store listing and the developer say it does.
Everything here comes from the live App Store listing and the developer’s site cannotwait.neoxapps.de, both checked on 2026-10-03. The app has been around since 2020 but has only a couple of ratings in the US store, so we judge it on features rather than reviews. Censuus ranks apps by the traffic they draw and by sponsorship, so paying also raises placement.
Counting down and counting up
Every event you add shows either how many days are left or how many have passed. A vacation or a deadline counts down, an anniversary or the day you started something counts up. Open an event and you see the same span in seconds, minutes, hours and days.
Widgets
The countdowns you care about most go on the Home Screen or the Lock Screen. Version 2.3 added an extra large widget for iPhone, so one big date can fill the screen.
Siri and Shortcuts
Ask Siri how many days are left until your vacation, or create an event hands-free. The developer says Siri AI works when it is available on your device. Events also show up in Spotlight, and the Shortcuts app can read your countdowns for your own automations.
Photo memories
For events that have already happened, CannotWait pulls matching photos from your Photo Library and builds a visual timeline of your milestones. You can also share a snapshot of a countdown with friends.
Design and privacy
You choose colour schemes and backgrounds, and the app is updated for Liquid Glass on iOS 27. The developer says there is no tracking with data linked to you and no fingerprinting, and that events are never shared or sold. The App Store privacy label lists analytics data that is not linked to you.
Verdict
CannotWait is a simple, free day counter from an independent developer who has kept it going since 2020, with good widgets and Siri support. It is iPhone first, there is no iPad layout listed, and there is no Ukrainian. To see it next to other counters, read our best days since and countdown apps.
