Verdict
The clearest difference is rating: WhenLog at 4.1 against Zetlog's 2.8. WhenLog also leads on ratings volume (2.5K vs 15) and iOS requirement (15.1 vs 17.4). On price, review sentiment, update cadence and ads 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. WhenLog sells 11 in-app purchases, starting at $1.99 per 7 days and Zetlog sells 8 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
WhenLog holds the better App Store score, 4.1 against 2.8. That said, the two scores are not equally well evidenced: WhenLog has 2.5K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 14% of WhenLog's written reviews are positive against 15% of Zetlog's, so the app with the better star average is not the one people write more warmly about.
WhenLog ships an update every 2 weeks, Zetlog every 3 weeks. The most recent releases landed on September 22, 2026 and August 24, 2026 respectively.
