Verdict
The clearest difference is in-app purchases: GPS Monster at none against CallApp's 13. GPS Monster also leads on ads (none vs shown) and rating (5.0 vs 4.6). CallApp's advantage is update cadence (fortnightly vs every 4 months) and ratings volume (715 vs 1). On price and device support there is nothing between them.
