# Harmony Fasting vs EsFast

The clearest difference is rating: Harmony Fasting at 4.7 against EsFast's 1.0. Harmony Fasting also leads on ads (none vs shown) and ratings volume (31 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Harmony Fasting sells 10 in-app purchases, starting at $0.99 per 7 days and EsFast sells 3 in-app purchases, starting at $29.99 per 3 months. Whichever you choose, the download price is not the number that matters.

Harmony Fasting holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Harmony Fasting has 31 ratings behind it against 1, so its average is the more settled of the two.

Harmony Fasting ships an update fortnightly, EsFast every 10 days. The most recent releases landed on June 8, 2026 and September 16, 2026 respectively.
