Ratings and reviews

everything fascinating just the way I wanted it to be but something is lacked which is Tan(x) on the Unit circle wich should make it even better and more ideal for me to compare them and keep them in mind otherwise best app I was looking for visual imagination of Unit circle

A "simple" but great app. Downloaded it a couple of days ago because I though it be interesting. And indeed today I needed it to refresh my old brain. The graphing quality is perfect. At first it looks a bit confusing as there are many graphs visible but this can be easily changed in the settings 👍 A "save" feature would be a nice addition but in my case a screenshot does the job as well

great application however I want to point out there is a spelling mistake when you click on information about sine. at the bottom the word amplitude is misspelled. otherwise great app :D
