# B Side vs 练就

The clearest difference is rating: B Side at 4.4 against 练就's 3.8. 练就's advantage is review sentiment (87% vs 63%) and update cadence (every 6 days vs fortnightly). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. B Side sells 1 one-off in-app purchase and 练就 sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

B Side holds the better App Store score, 4.4 against 3.8. Both are backed by a comparable volume of ratings — 8 and 12 respectively. Written reviews complicate that: 63% of B Side's written reviews are positive against 87% of 练就's, so the app with the better star average is not the one people write more warmly about.

B Side ships an update fortnightly, 练就 every 6 days. The most recent releases landed on September 5, 2026 and September 8, 2026 respectively.
