# 作业精灵 vs NB实验室

The clearest difference is rating: NB实验室 at 4.8 against 作业精灵's 3.5. NB实验室 also leads on ads (none vs shown) and update cadence (fortnightly vs monthly). 作业精灵's advantage is iOS requirement (12.0 vs 14.0). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. 作业精灵 sells 3 one-off in-app purchases and NB实验室 sells 10 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

NB实验室 holds the better App Store score, 4.8 against 3.5. Both are backed by a comparable volume of ratings — 150 and 93 respectively. Written reviews complicate that: 75% of 作业精灵's written reviews are positive against 72% of NB实验室's, so the app with the better star average is not the one people write more warmly about.

作业精灵 ships an update monthly, NB实验室 fortnightly. Both last shipped on November 6, 2026.
