Verdict
The clearest difference is in-app purchases: Modifiable at none against OnTrack's 2. Modifiable also leads on update cadence (every 10 days vs every 4 weeks) and iOS requirement (15.0 vs 18.6). OnTrack's advantage is ads (none vs shown). On price and device support there is nothing between them.
