A focus timer worth looking at. Most focus timers look like a spreadsheet with a countdown in it. This one is built the other way round. A single enormous numeral, bleeding off the edge of a field of acid green. Behind it, a mechanism that moves in time with the clock and never drifts. Rings that bounce, breathe, ripple inward, or pass momentum down a Newton's cradle. A square whose perimeter burns like a fuse, four seconds a side, for box breathing. When you start a session the whole field inverts to black and the numbers light up like something switched on behind them. Tap anywhere to start. Swipe to change the color. You never have to open a menu. 25/5, 50/10, 90/20, or count up. The classic pomodoro, longer ultradian blocks, or open-ended flow when you don't want a deadline. Timed properly. Built on timestamps, not ticks. Lock your phone, switch apps, come back: it is exactly where it should be. It tells you when you are done, even with the screen off. No account. No sync. No data leaves your phone. ACID INTERVAL PRO One payment unlocks all eight mechanisms, all ten colorways, and custom interval lengths. The timer itself is free and always will be.

Verdict
The clearest difference is ads: Acid Interval at none against ClearSpace's shown. Acid Interval also leads on rating (5.0 vs 4.7). ClearSpace's advantage is ratings volume (9K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ClearSpace sells 7 in-app purchases, starting at $6.99 per month and Acid Interval sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Acid Interval holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ClearSpace has 9K ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
