# 100% vs MERGE LAB

The clearest difference is rating: MERGE LAB at 4.8 against 100%'s 4.5. 100%'s advantage is update cadence (every 5 days vs every 3 weeks) and ratings volume (39 vs 11). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. 100% sells 1 one-off in-app purchase and MERGE LAB sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

MERGE LAB holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 39 and 11 respectively. Written reviews complicate that: 80% of 100%'s written reviews are positive against 72% of MERGE LAB'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, MERGE LAB every 3 weeks. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
