# Endorphins Running vs IndexFit

The clearest difference is ads: Endorphins Running at none against IndexFit's shown. Endorphins Running also leads on ratings volume (919 vs 4) and iOS requirement (16.4 vs 18.4). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Endorphins Running sells 4 in-app purchases, starting at $19.99 per month and IndexFit sells 5 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
