App is not useful for me, but I found out after buying a subscription (I already own most of the books and I had other expectations for the ‘bite size learning’ part). I subscribed via an ad that led to the website but no trial was presented to me nor did I know that the app is free to check it out beforehand. I have ADHD and I am an impulsive buyer, but usually it ends up alright since I can get a refund if something is not for me. I really like the idea but the terms and conditions are terrible, so to all potential users: please read it as it removes any EU citizen rights such as the right to withdraw within 14 days. I am so sad that I purchased a subscription for 60 euros and I was really excited, but unfortunately everything around this including the terms and conditions give me very bad vibes. I also found out that the app had a bad rep on Reddit, so I wonder why… To the owners, please make a more user centered subscription policy. This feels terrible and I will not recommend this app to anyone. Hope I can still get a refund..
