Verdict
Protractor Edge and ToolBox both sit at 4.5 stars, but that hides the real split: 70% of Protractor Edge's written reviews are positive against 32% of ToolBox's. Protractor Edge also leads on monetization model (freemium vs subscription) and iOS requirement (9.0 vs 11.3). ToolBox's advantage is ads (none vs shown) and update cadence (every 9 days vs every 43 months). On price, rating, in-app purchases and device support there is nothing between them.
