Verdict
The clearest difference is update cadence: 100% at every 5 days against MERGE LAB's every 3 weeks. 100% also leads on ratings volume (39 vs 10) and iOS requirement (7.0 vs 12.0). MERGE LAB's advantage is rating (4.8 vs 4.5). 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 10 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 September 20, 2026 and September 24, 2026 respectively.
