# PowerMon X vs Epoch Pro

The clearest difference is update cadence: PowerMon X at every 3 weeks against Epoch Pro's every 13 months. Epoch Pro's advantage is ratings volume (26 vs 5) and iOS requirement (13.0 vs 15.6). On price, rating, review sentiment and ads there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.0 for PowerMon X against 3.9 for Epoch Pro. That said, the two scores are not equally well evidenced: Epoch Pro has 26 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 67% of PowerMon X's written reviews are positive against 59% of Epoch Pro's.
