# Readest vs Mythos

The clearest difference is rating: Readest at 4.5 against Mythos's 4.2. Readest also leads on ratings volume (178 vs 6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Readest sells 6 in-app purchases, starting at $4.99 per month and Mythos sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Readest holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Readest has 178 ratings behind it against 6, so its average is the more settled of the two. Written reviews split almost evenly too, at 85% and 86% positive.

Readest ships an update fortnightly, Mythos every 2 weeks. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
