Red Wedge Timer
Read full descriptionHide full description
A timer a child can read before they can read a clock. Turn the dial to however long they have. A red disk fills that much of the hour, and shrinks as the time runs out — so "ten more minutes" stops being an abstract promise and becomes something visible, shrinking, on the table. When the disk is gone, the timer sounds. You choose what it sounds like — beeps, a chime, a cuckoo, marimba, a bell or a buzzer — and how long it keeps going: one second, ten, a minute, or until somebody stops it. Or nothing at all, if the room needs quiet. • Drag the dial, or tap 1 to 60 minutes • Six sounds, all generated by the app itself • Nothing to sign up for, no account, no adverts, no tracking • Works with the screen off Made for getting a small person off a screen, into shoes, or through the last stretch of homework without a countdown they cannot picture.

Verdict
The clearest difference is in-app purchases: Red Wedge Timer at none against Radar Chart Note's 1. Red Wedge Timer also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). On price and device support there is nothing between them.
