Verdict

The call

The clearest difference is rating: Protractor at 3.9 against Measure's 3.1. Protractor also leads on review sentiment (60% vs 27%) and update cadence (every 9 days vs every 6 months). Measure's advantage is ads (none vs shown) and ratings volume (1.8K vs 14). On price, in-app purchases and device support there is nothing between them.
