# Summer vs 白丁友记

The clearest difference is review sentiment: 白丁友记 at 100% against Summer's 48%. 白丁友记 also leads on rating (4.0 vs 2.2) and ads (none vs shown). Summer's advantage is ratings volume (62 vs 1) and iOS requirement (9.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Summer sells 9 in-app purchases, starting at $7.49 per month and 白丁友记 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

白丁友记 holds the better App Store score, 4.0 against 2.2. That said, the two scores are not equally well evidenced: Summer has 62 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 48% of Summer's written reviews are positive against 100% of 白丁友记's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
