Verdict
The clearest difference is rating: Contara at 5.0 against Netdata Mobile's 1.2. Contara also leads on update cadence (every 3 weeks vs every 6 weeks). Netdata Mobile's advantage is in-app purchases (none vs 1) and ratings volume (19 vs 1). On price, ads, device support and iOS requirement there is nothing between them.
