As someone enrolled in pre-calculus this was a huge help for me near the beginning of the year! but there is one feature I would love to recommend, such as picking what identities you want to practice. When I started off trying to memorize the unit circle I kept getting values like cot, sec, csc when I was just trying to practice the basic cos and sin and it would mess up my scores because I wasnt prepared for those values yet. I would recommend makinga feature where you can pick which identites you want to practice such as only doing sec, and csc, but not cos, tan, and sin Idk maybe its stupid but I feel like it would be good for students who are trying to strengthen a certian area and not just leaving them out in a trigonometry battlefield.

Thanks for the feedback! We're glad the app helped you in pre-calc.
That's a great suggestion, and we're actually working on a feature like this right now. Being able to choose which identities to practice should make it easier to focus on specific topics. Thanks for taking the time to share your idea!
