# 知到. vs i博导

The clearest difference is monetization model: 知到. at free against i博导's free with in-app purchases. 知到. also leads on ratings volume (322 vs 2) and review sentiment (20% vs 0%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. 知到. sells 11 in-app purchases, starting at $1.99 per month and i博导 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

知到. holds the better App Store score, 1.2 against 1.0. That said, the two scores are not equally well evidenced: 知到. has 322 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 20% of 知到.'s written reviews are positive against 0% of i博导's.

知到. ships an update every 3 weeks, i博导 every 2 weeks. The most recent releases landed on October 19, 2026 and October 15, 2026 respectively.
