Verdict

The call

The clearest difference is rating: HIITBURN at 4.3 against OptimalFit's 3.4. HIITBURN also leads on ratings volume (245 vs 17). OptimalFit's advantage is update cadence (every 3 days vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
