Verdict

The call

InstAddr and Potatso both sit at 4.5 stars, but that hides the real split: 87% of InstAddr's written reviews are positive against 58% of Potatso's. InstAddr also leads on iOS requirement (14.0 vs 17.0). Potatso's advantage is update cadence (every 5 days vs monthly) and ratings volume (6.2K vs 960). On price, rating, ads and in-app purchases there is nothing between them.
