There's a lot of bugs, had to reinstall twice to get options to come up on the courses screen, in lessons, the options would disappear if dragged and let go outside a slot, and also having to pay after just one lesson isn't very good. If I got a question wrong, it also didn't tell me the right answer, just moved on. It seems a bit hastily put together to be honest, but the idea is great.
Great app however there are a few bugs that I came across: 1. It's a bit difficult to drag options onto the placeholders. If you simply click on one, it just disappears and you are forced to quit and start the module from the beginning. 2. I would love to give you my money despite issue #1. However, when I click on upgrade to premium, the app crashes every time. In conclusion, I can't give you my money. :(
thought the app is pretty cool but it freezes on me in every module and it will not save my answers so Midway I have to start over repeatedly. like I will finish a problem with the right answer and it will be no option to continue. dragging the answers to the problem is less-than-ideal. I have a Google pixel 2XL so I have plenty of space..app too buggy...dangit.
BUG: in profile tab it shows me rank: novice all the time, even when I level up (only Next: eg. Hacker changes). I tried reinstalling, signing in and out, creating new account, nothing helps.
The app is well made. It's simplistic design looks gorgous. The performance is another story. On ones where I need to "Fill in the blanks" it fails. Some of the blocks disappear and I have to restart the app, which loses my progress, for it to work. It's very frustrating knowing the answer and not being able to answer. Otherwise I like the concept, the design. And the way you've gone about making/distributing this app.
Awesome app, especially for beginners and a wide range of courses to take. My only problem being the bug where if you tap an option sometimes it disappears until you restart the node.
Minor bug fixes and improvements
