Verdict
The clearest difference is in-app purchases: CDTimer + at none against AtoDays's 1. CDTimer + also leads on review sentiment (100% vs 71%) and iOS requirement (12.2 vs 26.0). AtoDays's advantage is rating (4.3 vs 4.0) and ratings volume (4 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AtoDays sells 1 one-off in-app purchase. CDTimer + asks for nothing beyond the download.
AtoDays holds the better App Store score, 4.3 against 4.0. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 71% of AtoDays's written reviews are positive against 100% of CDTimer +'s, so the app with the better star average is not the one people write more warmly about.
AtoDays ships an update every 6 weeks, CDTimer + every 5 weeks. The most recent releases landed on September 24, 2026 and September 17, 2026 respectively.
