# NB实验室 vs 中学物理实验室

The clearest difference is ads: NB实验室 at none against 中学物理实验室's shown. NB实验室 also leads on ratings volume (92 vs 1). 中学物理实验室's advantage is rating (5.0 vs 4.8). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. NB实验室 sells 10 in-app purchases, starting at $4.99 per month and 中学物理实验室 sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

中学物理实验室 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: NB实验室 has 92 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
