Verdict

The call

ISS Detector and Physics Toolkit Pro both sit at 4.6 stars, but that hides the real split: 56% of ISS Detector's written reviews are positive against 0% of Physics Toolkit Pro's. ISS Detector also leads on price (Free vs $1.99) and ratings volume (569 vs 7). Physics Toolkit Pro's advantage is in-app purchases (none vs 13) and ads (none vs shown). On rating and device support there is nothing between them.
