Verdict

The call

CANImmunize and SeamlessMD both sit at 4.6 stars, but that hides the real split: 90% of SeamlessMD's written reviews are positive against 29% of CANImmunize's. SeamlessMD also leads on monetization model (free vs ad-supported). CANImmunize's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (12.0 vs 16.4). On price, rating, ratings volume and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

CANImmunize holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 46 and 109 respectively. Written reviews complicate that: 29% of CANImmunize's written reviews are positive against 90% of SeamlessMD's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CANImmunize ships an update every 3 weeks, SeamlessMD every 2 months. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
