# Sequence vs ModelPlay

The clearest difference is rating: Sequence at 4.3 against ModelPlay's 3.0. Sequence also leads on ratings volume (65 vs 8). ModelPlay's advantage is review sentiment (27% vs 0%) and monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sequence sells 2 in-app purchases, starting at $9.99 per year and ModelPlay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sequence holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Sequence has 65 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 0% of Sequence's written reviews are positive against 27% of ModelPlay's, so the app with the better star average is not the one people write more warmly about.

Sequence ships an update every 10 days, ModelPlay every 2 weeks. The most recent releases landed on October 8, 2026 and October 11, 2026 respectively.
