# CORE40 vs Yoga Flow SF

The clearest difference is rating: Yoga Flow SF at 5.0 against CORE40's 2.3. Yoga Flow SF also leads on review sentiment (100% vs 60%) and iOS requirement (14.0 vs 16.0). CORE40's advantage is ads (none vs shown) and ratings volume (9 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Yoga Flow SF holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: CORE40 has 9 ratings behind it against 1, so its average is the more settled of the two.
