# Endorphins Running vs InstaCal

The clearest difference is update cadence: InstaCal at every 2 days against Endorphins Running's every 2 weeks. Endorphins Running's advantage is ratings volume (879 vs 24). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Endorphins Running sells 4 in-app purchases, starting at $19.99 per month and InstaCal sells 3 in-app purchases, starting at $7.99 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 Endorphins Running against 5.0 for InstaCal. That said, the two scores are not equally well evidenced: Endorphins Running has 879 ratings behind it against 24, so its average is the more settled of the two.
