# Readability vs Read Boost

The clearest difference is review sentiment: Read Boost at 100% against Readability's 56%. Read Boost also leads on in-app purchases (none vs 2) and rating (5.0 vs 4.6). Readability's advantage is ads (none vs shown) and update cadence (fortnightly vs every 5 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Readability sells 2 in-app purchases, starting at $19.99 per month. Read Boost asks for nothing beyond the download.

Read Boost holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Readability has 25K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 56% of Readability's written reviews are positive against 100% of Read Boost's.

Readability ships an update fortnightly, Read Boost every 5 months. The most recent releases landed on October 15, 2026 and September 23, 2026 respectively.
