Most of the questions are good ones, but they are phrased inconsistently and tend to be written with bad grammar. Also, the correct/incorrect answer result is shown in a way that is ugly and initially unintuitive.
Awesome app... I used this app from my friend mobile... Everything is really good.. I want to give you two suggestions, 1. The app name were different in Phone and Play store.. So, I can't able to find when I am searching in play store... 2. Explanation for the answers needs to be improved... Hope you will reach more Heights !!! Have a great future ahead!!! 😊😊😊
Very good app but having subscription for a month is not convincing me to purchase. One time fee for premium account is good option from consumer point of view atleast at starting stages of your application.
Good little review. A good way to test that you know what you think you know in terms of technical wording and functions. Just what I was missing! Turns out I wasn't clear on a few things 🙂
After installing, app is not opening, showing an error message "An error occurred while processing your request". In Android v 9. Seems proper testing was not done across different devices.
Seemed to be a good app but only worked once. Now getting an error "can't check if user is logged in" Tried to sign up, then received "unexpected error"
very good tool for learning however three days after registering i received and ransom email quoting the the password i used to sign up, im always cautious when creating accounts and it seems thats a good thing. Be aware that either your data isnt safe here or is being sold on for profit, be careful using this app!
Loving it, add more content mate. It's the perfect companion for a dev dude, add notification too. You deserve the subscription I pay mate. Cheers
It is a womderful app to test your knowledge on JS.The support team is also very active. Initially I had issues but it was resolved very fast.❤️
MAKE THE QUIZ OFFLINE. I'm on mya way home, that's when i use this app.but it can't work without wifi, make it offline
I rarely ever purchase an app, this one I'm likely buying. Great stuff for a beginner developer!
Keep it up, this is really helpful as a student!
Really awesome Javascript test and quiz app. I have review my knowledge a after class with this app and it really helpful.
It didn't open up. Showed the erroe couldn't check if a user is logged in or not.
Great work, but it takes two clicks to submit the answer, check it, add more content on angular and react
Really useful for me. I do the quiz everyday to improve my development skill.
its Good app...but they are charging for the content...i cant understand for what they are charging..the content they are providing i can have same through some free youtube tutorials or by referring some educational websites for free...
Dont paid for premium account . i paid for one month, and after 3 months i realized they still charging me. its very sneky and stypid from company, shame...
It is an very useful application if you are learning javascript. This is the nice app for es6 js, lot of questions and category wise.
Nice questions and exercises but the pricing is quite confusing IMO
Been a while since i woked with JS, used this app as a refresher to JS. Very helpful!
Very useful if you learning javascript. In other words this is the BEST app for es6 js
Very nice educational application to test your JavaScript skills and knowledge. Recommended.
It's not working. When I am trying to open it all I get is a white screen.
Very interesting and useful app for me as a java script developer. Love this app.
The internet issue is fixed now. Please add some more questions on React and Redux also.
I like this app. Rather than for theory, I am practicing with example and evaluating my knowledge.
totally awesome. I have learnt so much from this app. To the developer(s) great stuff

Best app to learn and practice JavaScript in easy way. Thanks
