# Dive Calculator vs Dive Kit

The clearest difference is update cadence: Dive Kit at every 4 days against Dive Calculator's every 12 months. Dive Kit also leads on rating (5.0 vs 4.7). Dive Calculator's advantage is monetization model (free vs freemium) and ratings volume (26 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Dive Calculator sells 2 one-off in-app purchases and Dive Kit sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Dive Kit holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Dive Calculator has 26 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.

Dive Calculator ships an update every 12 months, Dive Kit every 4 days. The most recent releases landed on November 6, 2026 and November 11, 2026 respectively.
