Do you know trigonometric functions? Or want to learn it? Generally it makes people to be complicated a little, but if you use Trig Func, this will help you to more easily understand! Also this app is easy/quick to confirm the value of trig functions, so I wish this is really useful for students, teachers, developers and more! *** Features *** - Visual trig functions! - Comfortable moving for calculations! - Great lists(sin,cos,tan,csc,sec,cot) - Images for the wave graphs *** How to use it *** [ Calc ] You can drag a radius line between 0 to 90 degrees, and if you do that, it will move to be based on "Radius" and "Angle". Also you can set any numbers up to text fields with segmented buttons. Such as if you edit Text1 with "X" button and Text2 with "Y" button, the triangle view will change to be based on "X" and "Y". Which means, there are 6 cases. ( Radius - Angle ) ( Radius - X ) ( Radius - Y ) ( Angle - X ) ( Angle - Y ) ( X - Y ) [ List ] No need to explain about it. Just scroll it. Oh, wait. You can change these values if you tap column names, like below... Degrees --- Radian sin --- csc(cosec) cos --- sec tan --- cot [ Wave ] There are 2 graphs, so if you tap the button of bottom right, the graph will change another one. (sin, cos, tan) --- (csc, sec, cot) Also you can tap anywhere for checking degrees and values. I hope this app helps you, even a little bit.

Verdict
The clearest difference is rating: Pythagoras Calculator at 4.6 against Visual Trig Func's 1.0. Pythagoras Calculator also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Visual Trig Func sells 1 one-off in-app purchase and Pythagoras Calculator sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Pythagoras Calculator holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Pythagoras Calculator has 242 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 61% of Visual Trig Func's written reviews are positive against 83% of Pythagoras Calculator's.
Visual Trig Func ships an update every 5 months, Pythagoras Calculator every 3 weeks. The most recent releases landed on October 4, 2026 and October 18, 2026 respectively.
