Dayfly is for notes you only need for a little while. Notes quietly disappear after 24 hours by default. Parking spots, Wi-Fi passwords, locker numbers, today-only reminders β jot it down and forget about it. Dayfly cleans up after itself. Attach photos and videos too. That whiteboard, a receipt, a photo you only took to ask an AI about β capture it and share it straight from Dayfly. Dayfly-managed attachments are removed when an expired note is cleaned up. Photo-library originals and shared copies remain. Want to keep something?

Verdict
The clearest difference is update cadence: todo.exe at every 5 days against Dayfly's fortnightly. todo.exe also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
