Verdict
The clearest difference is rating: CGX at 4.2 against TrackFit's 2.4. CGX also leads on update cadence (every 8 days vs every 5 months) and review sentiment (55% vs 26%). TrackFit's advantage is in-app purchases (none vs 2) and iOS requirement (11.0 vs 15.4). On price, ads and device support there is nothing between them.
