Ratings and reviews

This app has a lot of suspicious reviews all saying the same things, nothing specific (like you'd say if you actually used it to learn) and many around the same dates. It doesn't have very much information at all, and most of it is not adequately explained. Terms are used that have never been defined. Interface is nice, but it's not worth the download for so little information. Not well-thought out at all.

Sir when you want to earn money there is lot of other ways u can earn, but by using education app platform and showing ads on everytime a person clicks back button or goes to different page/topic is not the right way. People will tend to loose intrest on the subject as an whole which is far more disastrous to an individual and to the country as an whole. Net net : just reduce the number of adsthat pops up from nowhere while focusing on the subject. Use quick tutorial to help navigate in tool

Probably the best purely informational app I've seen of the dozen or so SQL apps I've used. Well layed out app and good variation of query formats shown. Explains many key conceots at a basic level. My only issue relates to a vagueness on some facts stated, ie. 8 character length database name limit - this isnt clear what type of SQL is being referenced, MS SQL (the assumed standard) 2008 has an 128 limit so this is far from accurate without being defined clearer.
