Verdict
The clearest difference is review sentiment: OMama at 50% against CANImmunize's 29%. OMama also leads on monetization model (free vs ad-supported). CANImmunize's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.
