JB4 Mobile's advantage is rating (3.8 vs 3.0) and ratings volume (239 vs 4). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

DTE PowerControl is free to download; JB4 Mobile costs $27.99 up front. Neither carries in-app purchases, so what you see is what you pay.

JB4 Mobile holds the better App Store score, 3.8 against 3.0.
