# 零五网 vs NB实验室

The clearest difference is in-app purchases: 零五网 at none against NB实验室's 41. 零五网 also leads on update cadence (weekly vs fortnightly) and iOS requirement (12.0 vs 14.0). NB实验室's advantage is ads (none vs shown) and review sentiment (72% vs 38%). On price and device support there is nothing between them.

Both are free to download. NB实验室 sells 41 in-app purchases, starting at $4.99 per month. 零五网 asks for nothing beyond the download.

NB实验室 holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: NB实验室 has 90 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 38% of 零五网's written reviews are positive against 72% of NB实验室's.

零五网 ships an update weekly, NB实验室 fortnightly. The most recent releases landed on October 10, 2026 and October 29, 2026 respectively.
