# V.O2 vs Endorphins Running

V.O2 and Endorphins Running both sit at 4.9 stars, but that hides the real split: 98% of Endorphins Running's written reviews are positive against 71% of V.O2's. V.O2's advantage is ratings volume (6.3K vs 916). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. V.O2 sells 16 in-app purchases, starting at $12.99 per month and Endorphins Running sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for V.O2 against 4.9 for Endorphins Running. That said, the two scores are not equally well evidenced: V.O2 has 6.3K ratings behind it against 916, so its average is the more settled of the two. Written reviews are what separate them: 71% of V.O2's written reviews are positive against 98% of Endorphins Running's.
