# OpenWorkout vs GainFrame

The clearest difference is rating: GainFrame at 4.9 against OpenWorkout's 4.0. GainFrame also leads on review sentiment (88% vs 50%) and ratings volume (71 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. OpenWorkout sells 2 in-app purchases, starting at $3.99 per month and GainFrame sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
