# CIT vs 医知源

The clearest difference is in-app purchases: CIT at none against 医知源's 4. CIT also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. 医知源 sells 4 one-off in-app purchases. CIT asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for CIT against 5.0 for 医知源. That said, the two scores are not equally well evidenced: CIT has 8 ratings behind it against 1, so its average is the more settled of the two.

CIT ships an update every 2 weeks, 医知源 every 2 months. The most recent releases landed on October 23, 2026 and October 30, 2026 respectively.
