Verdict
The clearest difference is in-app purchases: NUBOXX at none against Justfit's 7. NUBOXX also leads on ads (none vs shown) and iOS requirement (11.0.0 vs 15.0). Justfit's advantage is update cadence (every 3 days vs every 3 weeks). On price, rating, ratings volume and device support there is nothing between them.
