Verdict
The clearest difference is in-app purchases: Sight Pocket at none against CrossMetronome's 2. Sight Pocket also leads on iOS requirement (15.1 vs 17.6). CrossMetronome's advantage is update cadence (every 3 days vs every 6 weeks). On price, ads and device support there is nothing between them.
