# Numlab vs WhenLog

The clearest difference is rating: WhenLog at 4.1 against Numlab's 2.0. WhenLog also leads on ratings volume (2.5K vs 23) and update cadence (every 2 weeks vs monthly). Numlab's advantage is iOS requirement (11.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Numlab sells 7 in-app purchases, starting at $7.99 per 7 days and WhenLog sells 11 in-app purchases, starting at $1.99 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 2.0. That said, the two scores are not equally well evidenced: WhenLog has 2.5K ratings behind it against 23, so its average is the more settled of the two. Written reviews point the same way: 0% of Numlab's written reviews are positive against 14% of WhenLog's.

Numlab ships an update monthly, WhenLog every 2 weeks. The most recent releases landed on June 5, 2026 and September 22, 2026 respectively.
