Verdict
The clearest difference is review sentiment: KAMI 2 at 84% against iDoctor's 22%. KAMI 2 also leads on update cadence (every 2 months vs every 105 months) and ratings volume (15K vs 1). iDoctor's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. iDoctor sells 1 one-off in-app purchase and KAMI 2 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
iDoctor holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: KAMI 2 has 15K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 22% of iDoctor's written reviews are positive against 84% of KAMI 2's, so the app with the better star average is not the one people write more warmly about.
iDoctor ships an update every 105 months, KAMI 2 every 2 months. The most recent releases landed on September 28, 2026 and October 16, 2026 respectively.
