Verdict

The call

The clearest difference is review sentiment: C at 100% against F45 Training's 28%. C also leads on rating (5.0 vs 4.5) and update cadence (every 5 days vs every 10 days). F45 Training's advantage is in-app purchases (none vs 2) and ratings volume (205 vs 5). On price, ads, device support and iOS requirement there is nothing between them.
