Verdict

The call

The clearest difference is rating: CANImmunize at 4.6 against First Aid's 4.2. CANImmunize also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (12.0 vs 26.0). First Aid's advantage is monetization model (free vs ad-supported). On price, review sentiment, 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 4.2. Both are backed by a comparable volume of ratings — 46 and 28 respectively. Written reviews complicate that: 29% of CANImmunize's written reviews are positive against 32% of First Aid'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, First Aid every 3 months. The most recent releases landed on October 19, 2026 and October 22, 2026 respectively.
