Thanks a lot for the review! ### 4/5 — love it but could be better *2025-08-08* Love it but could be better ### 1/5 — u cant draw 4 *2025-06-28* u cant draw 4 ### 1/5 — Not challenging enough. Can only trial with annual subscription *2025-05-21* The only way to get a free trial is to sign up for the annual subscription. I thought I had cancelled the free trial but I didn’t so it charged me the ridiculous amount of 37$ for this app for a YEAR. And I was denied a refund for it twice. The game is not challenging enough for my 4 year old yet I’m stuck with this app and can’t get my 37$ back. How am I not allowed a refund on a product I know they are capable of refunding? I don’t want it anymore!!!! It’s not a good app!!!!! They do this on purpose because there’s not a single other kids app I purchased for my son that requires the annual subscription to trial. ## Frequently asked questions about Kahoot!
