# 1 vs ZenClock

The clearest difference is review sentiment: 1 at 82% against ZenClock's 50%. 1 also leads on rating (4.4 vs 4.0) and ratings volume (138 vs 4). ZenClock's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 1 sells 1 one-off in-app purchase and ZenClock sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

1 holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: 1 has 138 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 82% of 1's written reviews are positive against 50% of ZenClock's.

1 ships an update monthly, ZenClock every 3 months. Both last shipped on November 1, 2026.
