# 100% vs Devolver Tumble Time

The clearest difference is ads: 100% at none against Devolver Tumble Time's shown. 100% also leads on review sentiment (80% vs 56%) and update cadence (every 5 days vs fortnightly). Devolver Tumble Time's advantage is ratings volume (920 vs 39) and rating (4.7 vs 4.5). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 100% sells 1 one-off in-app purchase and Devolver Tumble Time sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Devolver Tumble Time holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Devolver Tumble Time has 920 ratings behind it against 39, so its average is the more settled of the two. Written reviews complicate that: 80% of 100%'s written reviews are positive against 56% of Devolver Tumble Time'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, Devolver Tumble Time fortnightly. The most recent releases landed on September 20, 2026 and September 19, 2026 respectively.
