# 100% vs Sequence

The clearest difference is rating: Sequence at 5.0 against 100%'s 4.5. 100%'s advantage is update cadence (every 5 days vs every 3 months) and ratings volume (39 vs 4). On price, ads, 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 Sequence sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sequence holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: 100% has 39 ratings behind it against 4, so its average is the more settled of the two.

100% ships an update every 5 days, Sequence every 3 months. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
