# Perimify vs Epoch Pro

The clearest difference is rating: Perimify at 5.0 against Epoch Pro's 4.0. Perimify also leads on review sentiment (100% vs 59%) and update cadence (every 5 weeks vs every 13 months). Epoch Pro's advantage is ads (none vs shown) and ratings volume (25 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Perimify holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Epoch Pro has 25 ratings behind it against 1, so its average is the more settled of the two.
