# KarbCoach vs Stretchly

The clearest difference is rating: KarbCoach at 5.0 against Stretchly's 4.2. KarbCoach also leads on iOS requirement (15.1 vs 17.5). Stretchly's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KarbCoach sells 1 in-app purchase, starting at $9.99 per month and Stretchly sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

KarbCoach holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Stretchly has 10 ratings behind it against 2, so its average is the more settled of the two.
