# Epi Tools vs iECHO

The clearest difference is rating: Epi Tools at 5.0 against iECHO's 2.9. Epi Tools also leads on review sentiment (100% vs 60%) and iOS requirement (13.4 vs 15.0). iECHO's advantage is ratings volume (9 vs 1) and update cadence (every 4 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Epi Tools holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: iECHO has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Epi Tools's written reviews are positive against 60% of iECHO's.

Epi Tools ships an update every 2 months, iECHO every 4 weeks. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
