# Flow Fit vs Sumaddle

The clearest difference is ads: Sumaddle at none against Flow Fit's shown. Sumaddle also leads on review sentiment (95% vs 69%) and update cadence (every 3 weeks vs every 2 months). Flow Fit's advantage is ratings volume (6.7K vs 769) and iOS requirement (10.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flow Fit sells 4 one-off in-app purchases and Sumaddle sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Flow Fit against 4.9 for Sumaddle. That said, the two scores are not equally well evidenced: Flow Fit has 6.7K ratings behind it against 769, so its average is the more settled of the two. Written reviews are what separate them: 69% of Flow Fit's written reviews are positive against 95% of Sumaddle's.

Flow Fit ships an update every 2 months, Sumaddle every 3 weeks. Both last shipped on November 3, 2026.
