Verdict

The call

The clearest difference is ads: Zen Flip Clock at none against Simple Clock's shown. Zen Flip Clock also leads on ratings volume (6.2K vs 297) and rating (4.7 vs 4.5). Simple Clock's advantage is iOS requirement (11.0 vs 15.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Zen Flip Clock holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Zen Flip Clock has 6.2K ratings behind it against 297, so its average is the more settled of the two. Written reviews complicate that: 72% of Zen Flip Clock's written reviews are positive against 75% of Simple Clock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Zen Flip Clock ships an update every 2 weeks, Simple Clock fortnightly. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
