Verdict
The clearest difference is rating: OneBook at 5.0 against soso背单词's 4.6. OneBook also leads on ratings volume (64 vs 9). soso背单词's advantage is monetization model (free vs freemium). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. soso背单词 sells 3 one-off in-app purchases and OneBook sells 2 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.
OneBook holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: OneBook has 64 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of soso背单词's written reviews are positive against 97% of OneBook's, so the app with the better star average is not the one people write more warmly about.
soso背单词 ships an update every 2 weeks, OneBook weekly. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
