# 100% vs Ocean Blast!

The clearest difference is review sentiment: 100% at 80% against Ocean Blast!'s 40%. 100% also leads on ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). Ocean Blast!'s advantage is rating (4.7 vs 4.5). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. 100% sells 1 one-off in-app purchase and Ocean Blast! sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Ocean Blast! holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 39 and 72 respectively. Written reviews complicate that: 80% of 100%'s written reviews are positive against 40% of Ocean Blast!'s, so the app with the better star average is not the one people write more warmly about.

100% ships an update every 5 days, Ocean Blast! every 3 weeks. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
