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 — 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 — the disc starts full either way. Prefer the classic 60-minute dial? Switch with one tap. ON YOUR LOCK SCREEN TOO — FREE The disc keeps shrinking on the Lock Screen and in the Dynamic Island, without opening the app. Use it as a laundry timer — 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 • Full-screen shrinking disc • Presets from 1 minute to 1 hour, Wash 52 min and Dry 60 min, or any time you like • Whole-circle or 60-minute dial • End sound and vibration • Lock Screen and Dynamic Island disc SLOWDIAL PRO — one-time purchase, no subscription • Classroom mode: just the disc, full screen. Taps don't stop it. Hide the numbers. Pick the color. • Sequences: "Clean up 5 min → Wash hands 3 min → Snack", with a picture and a word for each step • Controls (iOS 18 or later): start your favorite timer from Control Center, the Lock Screen or the Action Button • Home Screen and Lock Screen widgets PRIVATE BY DESIGN • No account. Your timers stay on your iPhone. • Only anonymous usage counts are sent (which parts of the app are used) — never your timer names. You can turn this off in Settings.

Verdict
The clearest difference is in-app purchases: MathZombie! at none against Slowdial's 1. MathZombie! also leads on iOS requirement (15.0 vs 17.0). Slowdial's advantage is ads (none vs shown). On price and device support there is nothing between them.
