Verdict
The clearest difference is in-app purchases: GSM Control at none against ScanNet's 1. GSM Control also leads on ads (none vs shown) and iOS requirement (7.0 vs 17.2). ScanNet's advantage is update cadence (every 2 months vs every 17 months). On price and device support there is nothing between them.
