The website is great. The android app is VERY buggy. Not very user friendly at all, especially on a tablet. You need to improve on that front. Further, all features such as notes are unavailable on the app. A lot of students may not have access to PCs and Laptops and a cheap android tablet may be their only access point. It is imperative that you make sure you can provide for them especially when paying (no small amount for many) for this service! Else, excellent videos, very appreciated!
