Verdict

The call

The clearest difference is rating: SignalScope X at 3.0 against Spectrum Compact Simulator's 1.0. SignalScope X also leads on ratings volume (23 vs 1) and update cadence (every 3 weeks vs every 2 months). Spectrum Compact Simulator's advantage is in-app purchases (none vs 10) and iOS requirement (7.1 vs 18.6). On price, ads and device support there is nothing between them.
