Verdict

The call

The clearest difference is rating: CO at 4.5 against ProWatch's 2.5. CO also leads on ratings volume (1.2K vs 2). ProWatch's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
