Verdict
The clearest difference is monetization model: Rep Track at free with in-app purchases against Air Quality Watch's subscription. Air Quality Watch's advantage is device support (3 vs 1) and iOS requirement (18.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.
