# Synopsis Plus vs ReadCheck

The clearest difference is ratings volume: ReadCheck at 20 against Synopsis Plus's 1. Synopsis Plus's advantage is rating (5.0 vs 4.8) and iOS requirement (15.5 vs 18.5). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Synopsis Plus sells 11 in-app purchases, starting at $5.99 per month and ReadCheck sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Synopsis Plus holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: ReadCheck has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Synopsis Plus ships an update every 11 days, ReadCheck weekly. The most recent releases landed on October 3, 2026 and October 8, 2026 respectively.
