# Log vs QH

The clearest difference is ratings volume: QH at 15 against Log's 2. QH also leads on iOS requirement (15.6 vs 18.0). Log's advantage is device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 5.0 for Log against 5.0 for QH. That said, the two scores are not equally well evidenced: QH has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 20, 2026 and October 17, 2026 respectively.
