Dive Log also leads on review sentiment (84% vs 52%) and update cadence (monthly vs every 18 months). iDeco Pro's advantage is in-app purchases (none vs 13) and price ($8.99 vs $14.99). On ads, chart position and device support there is nothing between them.

Dive Log costs $14.99 and iDeco Pro $8.99 up front. Dive Log sells 11 one-off in-app purchases. iDeco Pro asks for nothing beyond the download.

Dive Log holds the better App Store score, 4.7 against 3.9.
