# Deep Tools vs Dive Planner Calculator

The clearest difference is price: Deep Tools at Free against Dive Planner Calculator's $8.99. Deep Tools also leads on rating (4.6 vs 3.3) and update cadence (every 6 weeks vs every 7 months). Dive Planner Calculator's advantage is in-app purchases (none vs 3) and review sentiment (67% vs 50%). On ads and device support there is nothing between them.

Deep Tools is free to download; Dive Planner Calculator costs $8.99 up front. Deep Tools sells 3 in-app purchases, starting at $2.99 per month. Dive Planner Calculator asks for nothing beyond the download.

Deep Tools holds the better App Store score, 4.6 against 3.3. That said, the two scores are not equally well evidenced: Deep Tools has 93 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of Deep Tools's written reviews are positive against 67% of Dive Planner Calculator's, so the app with the better star average is not the one people write more warmly about.

Deep Tools ships an update every 6 weeks, Dive Planner Calculator every 7 months. The most recent releases landed on September 15, 2026 and September 2, 2026 respectively.
