Good for children (i guess) The idea is cute but imho accomplishes nothing. It tries to "gamefy" the learning experience but just muddles the learning in the process. I can see this being a fun way to learn about our world for small children or maybe young teens, but the site is definitely marketed towards all age groups. Just reading the wikipedia article about whatever subject you want to learn will most likely get you a better grasp on the topic than spending money on the premium subscription, which a lot of it is being spend on making 'cute animations' and keeping the app running. I have yet to come across actual exercises which require any deeper skill whatsoever. If you have a small child at home which wants to learn about science and the like in a playful way or if you are an adult and want to feel like you are learning something new on your commute this is probably not something bad. For me though this feels like another attempt to make an app for something which does not need it. Buy a book instead.

A great app for learning A great app for learning. Sadly though, I didn't have time to use it and had to cancel my subscription only to realize that the said subscription already started. However, with their great support, they were able to help me sort it out with a refund. Nothing but great experience so far. I highly recommend it!!

Amazing App They really deliver what they advertise. I really enjoyed how courses are structured and they help on improving your problem solving approach. Once you start you can't stop, keep saying one more, one more. I love it.

Can't cancel 7-day trial (solved) Tried to cancel the trial before deadline, but the cancel subscription button won't work (still doesn't work now). No way to cancel, I got billed €124,95. Immediately requested for a refund and haven't used any courses since being charged, will update if I receive it. Be careful with this company. UPDATE: Thanks you Steph from customer service, who has promptly issued a full refund after an email. It may be better to directly email the support team rather than to submit a refund request through the app. The app itself is good to awaken a beginner's interest, but offers not much after that. If you want to cancel a trial, make sure to do so through email to be safe.

Amazing resource It's the kind of resource that any student should have. It has a great approach, and you learn by doing. Besides the website being an amazing tool, their team is incredibly responsive and helpful for any support issues.
