Verdict

The call

The clearest difference is review sentiment: Breaz at 100% against SleepTrack's 39%. Breaz also leads on update cadence (every 3 days vs every 2 months). SleepTrack's advantage is ads (none vs shown) and iOS requirement (8.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
