Verdict
The clearest difference is price: EK1 Tuning cloud at Free against JB4 Mobile's $27.99. EK1 Tuning cloud also leads on update cadence (every 2 weeks vs every 3 months). JB4 Mobile's advantage is rating (3.8 vs 1.3) and ratings volume (239 vs 3). On ads, in-app purchases, monetization model and device support there is nothing between them.
