# Dive Diary vs Diving logbook

The clearest difference is in-app purchases: Dive Diary at none against Diving logbook's 3. Dive Diary also leads on review sentiment (90% vs 76%) and device support (3 vs 1). Diving logbook's advantage is rating (4.2 vs 4.0) and ratings volume (96 vs 19). On price, update cadence and ads there is nothing between them.

Both are free to download. Diving logbook sells 3 in-app purchases, starting at $1.99 per month. Dive Diary asks for nothing beyond the download.

Diving logbook holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Diving logbook has 96 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 90% of Dive Diary's written reviews are positive against 76% of Diving logbook's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 18, 2026 and September 25, 2026 respectively.
