Verdict

The call

The clearest difference is update cadence: Justfit at every 3 days against Next Up's every 5 weeks. Justfit also leads on review sentiment (100% vs 76%) and rating (5.0 vs 4.7). Next Up's advantage is ratings volume (2.8K vs 1) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
