# Lab4U vs Science Experiments by Dencity

The clearest difference is rating: Science Experiments by Dencity at 5.0 against Lab4U's 4.5. Lab4U's advantage is ads (none vs shown) and ratings volume (10 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
