Slowdial shows time as an amount: a colored disc that shrinks as time passes. Children (and grown-ups) can see "how much is left" without reading a clock. NO ADS, EVER. Slowdial never shows an ad β€” not before the timer, not after it. It is safe to hand to a child or to put in front of a class. THE TIME YOU PICK FILLS THE WHOLE CIRCLE Pick 5 minutes or 45 β€” the disc starts full either way. Prefer the classic 60-minute dial? Switch with one tap. ON YOUR LOCK SCREEN TOO β€” FREE The disc keeps shrinking on the Lock Screen and in the Dynamic Island, without opening the app. Use it as a laundry timer β€” watch the washer and dryer count down on your Lock Screen. When time is up you get a sound and a vibration, even with the screen locked. FREE β€’ Full-screen shrinking disc β€’ Presets from 1 minute to 1 hour, Wash 52 min and Dry 60 min, or any time you like β€’ Whole-circle or 60-minute dial β€’ End sound and vibration β€’ Lock Screen and Dynamic Island disc SLOWDIAL PRO β€” one-time purchase, no subscription β€’ Classroom mode: just the disc, full screen. Taps don't stop it. Hide the numbers. Pick the color. β€’ Sequences: "Clean up 5 min β†’ Wash hands 3 min β†’ Snack", with a picture and a word for each step β€’ Intervals: get ready, then work and rest for up to 20 rounds (a Tabata sample is included). Each interval session can be saved to Apple Health as a workout if you turn it on. β€’ Controls (iOS 18 or later): start your favorite timer from Control Center, the Lock Screen or the Action Button β€’ Home Screen and Lock Screen widgets PRIVATE BY DESIGN β€’ No account. Your timers stay on your iPhone. β€’ Only anonymous usage counts are sent (which parts of the app are used) β€” never your timer names. You can turn this off in Settings.
