# Flat vs Composer Pro

The clearest difference is monetization model: Flat at freemium against Composer Pro's subscription. Flat also leads on update cadence (fortnightly vs every 2 months) and ratings volume (7K vs 697). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Flat sells 10 in-app purchases, starting at $9.99 per month and Composer Pro sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Flat against 4.5 for Composer Pro. That said, the two scores are not equally well evidenced: Flat has 7K ratings behind it against 697, so its average is the more settled of the two. Written reviews are what separate them: 68% of Flat's written reviews are positive against 72% of Composer Pro's.

Flat ships an update fortnightly, Composer Pro every 2 months. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
