★★★★★ Grim Reaper · Feb 6, 2021

★★★★☆ Francine Nyiramana · Feb 3, 2022
I give it a four because its kinda fun but kinda not fun when I installed it I thought it would have more than a mental age quiz oh well
★☆☆☆☆ Steve Clark · Jan 31, 2023
4 times the ads. Example.ad.then here's test 1.ad. Title of no.1 ad.answer questions to no.1 question than ad. Before your results of no.1 question you get an ad.title of 2nd question ad get ready to take test ad take test ad.answer to no2 ad. So on and so on. It is a waste of time...ugh
★☆☆☆☆ fares acount · Oct 11, 2021
Stupid questions The same stupid 4 results You can sheet very easily
★☆☆☆☆ Cody Mcdonald · May 11, 2022
To me this is not a brain age test a brain age test should be compiled of puzzles quizzes memory puzzles, and it should be about 60 questions or more and then your brain age this is like 6,7 questions it tells you your brain age then six or seven more questions and another brain age.... and it makes me feel bad putting a 1-star I have never put a 1-star on any app but unless this app improves what I've seen so far no it is a one-star app in my opinion
