Verdict

The call

The Image Converter □ and SlimSpace both sit at 4.6 stars, but that hides the real split: 67% of SlimSpace's written reviews are positive against 29% of The Image Converter □'s. SlimSpace also leads on update cadence (every 2 weeks vs every 5 months). The Image Converter □'s advantage is ads (none vs shown) and ratings volume (17K vs 998). On price, rating, in-app purchases and monetization model there is nothing between them.
