# Wunder vs 书影

The clearest difference is rating: Wunder at 5.0 against 书影's 4.0. Wunder also leads on review sentiment (100% vs 64%) and update cadence (every 2 days vs every 4 days). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Wunder sells 3 in-app purchases, starting at $2.99 per month and 书影 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Wunder holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews point the same way: 100% of Wunder's written reviews are positive against 64% of 书影's.
