All three count days. They differ in what they are built around: CannotWait keeps your countdowns and anniversaries simple and adds Siri, Shortcuts and photo memories, DayCount organises many events with categories, streaks and reminders, and Days Since is a counter for how long since you last did something. Here is how they compare.
Compared on how each counts, widgets and extras, from the CannotWait App Store listing (read 2026-10-03) and the facts we verified for our days since apps roundup. We do not quote prices or ratings.
| CannotWait | DayCount | |
|---|---|---|
| Counts | Days left or days passed, down to seconds | Time before and after each event, plus streaks |
| Organising | A list of events with your colours and backgrounds | Your own categories with images, repeating events, notes |
| Widgets | Home Screen, Lock Screen, extra large iPhone widget | Home Screen and Lock Screen with your own fonts and textures |
| Extras | Siri, Shortcuts, Spotlight, photo memories, sharing | Alerts before or after a date, a daily summary |
DayCount is built for many events at once: categories with images, events that repeat daily, weekly or monthly, a note on each, daily streaks and alerts before or after a date. CannotWait keeps the list simpler and leans on Siri, Shortcuts, Spotlight and photo memories for past events.
Days Since gives each habit you want to drop its own counter, such as the last time you smoked, so the number reminds you not to reset it. CannotWait can count up from any past date too, but it is built mainly around birthdays, trips, deadlines and anniversaries.
It wins on Siri and Shortcuts support, photo memories, eight interface languages and a free model with no in-app purchases listed. It has fewer organising tools than DayCount and is not focused on habits like Days Since.
