If you have ever looked up and lost an hour, you do not need another number counting down. You need to see time move. Tempo turns time into something you can watch. A dandelion loses its seeds. An eclipse closes over. A snowman gives in to the sun. Glance at your phone from across the room and you know how much is left — no reading, no math. BUILT FOR TIME BLINDNESS Numbers are abstract. If your brain does not track elapsed time on its own, "20 minutes" means nothing until it is already gone. Tempo makes time spatial instead, so you feel it draining rather than having to calculate it. FROM ONE MINUTE TO ONE YEAR Most timers stop at an hour. Tempo has six scales: • MINUTE — a focus sprint or a short break • HOUR — the meeting, the work block • DAY — how much of today is actually left • MONTH — the deadline that still feels far away • SEASON (Pro) — the three months you keep meaning to use • YEAR — the one nobody shows you The longer scales run live against the real calendar. Open Tempo in October and the year is already most of the way gone. That is not a gimmick — for anyone who loses whole weeks, seeing it is the point. SEVEN VISUALIZATIONS Dandelion, Dots, Eclipse, Ember, Sand, Snowman, and Thunderstorm. Pick the one your brain actually reads, and set it as your default. ON YOUR WRIST AND LOCK SCREEN An Apple Watch app and Lock Screen and Home Screen widgets keep your current scale in view without opening anything — so checking the time stops being the distraction. BUILT TO STAY QUIET • No account, no sign-up, no email • Works entirely offline • No streaks, no badges, no guilt mechanics • No ads, ever Tempo will not fix your relationship with time. It just makes time visible, so the hours stop disappearing without warning. Free: the Dots visualization and five of the six scales — MINUTE, HOUR, DAY, MONTH, and YEAR. A one-time Pro purchase adds Dandelion, Eclipse, Ember, Sand, Snowman, Thunderstorm, and the SEASON scale. No subscription.

Time you can't see is time you can't feel. Sundae turns it into something you can watch — an ice cream that melts, a candle that burns down, a train that rides home. Start a session, set your phone down, and just glance. MADE FOR TIME BLINDNESS • Every second is visible: the scene is consumed smoothly in real time, on screen and on your Lock Screen • Live Activity + Dynamic Island: the melting sundae stays with you even when the phone is face up on your desk • Start in three seconds: two taps, no setup, no account NO GUILT. EVER. • Step away anytime — your session just naps. Nothing withers, nothing breaks, nothing is lost • Streaks only celebrate. Miss a day and the app simply says nothing • Rest counts: Lounge Mode is an official do-nothing timer. A sun sets over the sea while you lie flat. Finishing a rest keeps your streak alive A FRIEND, NOT A COACH • Pebble the sea otter waits with you, naps with you, and floats in the dessert lake when you finish • Write one thing ("Reply to Sam's email") and the whole app becomes about just that — even on your Lock Screen • Finished time becomes a collection of little dioramas ONE THING A DAY • Tell Sundae what you're working toward, and roughly how you'd get there • Each day it puts a single step on your Lock Screen — tap it and you're focusing • Skip one and it rotates to the next. Nothing is ever overdue, nothing accumulates • Never a list, never a checkbox, never a nag TWELVE SCENES, THREE UNIVERSES • Dessert: Sundae, Popsicle, Hot Cocoa, Cotton Candy • Flame: Candle, Campfire, Sparkler, Firefly Jar • Journey: Night Train, Sailboat, Balloon, Snail SOUND THAT ACTUALLY HELPS • Real rain and ocean recordings, crackling fireplace, summer crickets, brown noise • Gentle music-box chime when you finish — never an alarm PAY ONCE. YOURS FOREVER. • Free: full timer, Pebble, and three scenes • Sundae Full ($9.99, one-time): every scene, Lounge Mode, the full collection • Never a subscription PRIVATE BY DESIGN • Works completely offline. No account, no ads, no tracking, no data collected — the app has no networking capability at all

Verdict

The call

The clearest difference is update cadence: Sundae at every 4 days against Tempo's fortnightly. Tempo's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
