This is the only tool You'll Ever Need 2 understand the unit circle. Words can't express how impressed I am with this super professional effort. If you've ever wanted to visualize the trigonomic functions this product beats them all. Kudos to the development team

remove the 720p god awful pixel art random trig function background and 5 stars. That horrid thing is nothing but a distraction from the needed information the unit circle provides. There is no need for anything but a black background - anything else just hinders the ability to easily read the circles values at a glance.

There is a bug that causes a large "hang" when you go from certain sections to others, within the app. If you're patient, it unfreezes and works well. The app is gorgeous and with a lot of depth. If the developers can smash that freezing issue there's nothing else to do. Great app. The app hung 3 times trying to load it the very first time. I ended it twice and the third time i decided just to wait and eventually it did load. It's still slow to load now... In fact just went unresponsive and never loaded. Funny because I'm trying to get into it to tell you which screens it takes time to flip between and I can't load the app at all.

What is this disgusting background they added. This was 5 star now 1 star. I can't believe ANYONE thought that was a good idea. Fix it.

I paid 0.5$ in order to keep an ad free app. Freeze on android 6 after the first launch.... Can you remove the bug please ?

Crashes everytime when I'm changing page in this app to formulas. Btw very good app. Thank you as much as needed.

Man, I wish I knew about this over the last 2 years of calculus! Even after 10 minutes with the app, I understand trig a little better. I think the function values tab computer. I'm definitely jumping to this next time I need a trig reference.

Please, remove the distracting transparent background. I promise will immediately purchase this beautiful software.

Doesn't work. Starts up on a gray screen and stays like that

Such a wonderful app. Truly helps with a visual learners understanding of the less obvious side of Trig

Will buy when that background is removed, blends in with text and looks too clustered...

This is quite interesting. Is there a reason why the quadrants have the 2nd and 4th quadrants as in app?

Extremely impressed with this app. So much so, that I purchased it about a minute after I first opened it. I am not a novice when it comes to trigonometry and its use in calculus, physics, etc. But this app thought me something new within minutes: visualization of functions other than sin and cos. Aside being robust, this has to be one of the most beautiful apps I have ever seen. KUDOS to the developers.

The idea and graphics are awesome but doesn't launch in the first go. I just get a blank grey screen instead. If I'm lucky it starts up in ~5 tries or else... Hope you fix it. Phone model: letv le2 launcher: drupe

I feel obligated to come back and give this a 5-star review! I'm very much not big on hyperbole, but this app has changed my understanding of trigonometry completely. I've never been able to visualize these quantities directly before, but after working with this for a few days I suddenly "got" it! Simply awesome! I highly recommend it if you are studying trig.

This app revolutionized my understanding of trigonometry within a minute of first opening it. The mind shudders at the beauty of mathematics - and then to shudder at the idea that before computers, A MAN IMAGINED THIS! Brilliant execution. This is what development is all about.

If you try to open the app, you may need about 3 minutes or much more in order to just navigate in the app. I uninstalled it and then install it again. Just worked for 1 time and then just every time I try to open it the phone crashes and never opened again... So sad.. It seems to be a good app..
