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.

About

Galton Board

Explore probability theory with a simulation of the classic Galton board. Adjust board size, send numerous balls through a pin maze, and observe emergent patterns visualized in a bar chart. Ideal for educational purposes, it helps grasp concepts of chance and their relation to Pascal's Triangle.

Highlights
  • Galton board simulation
  • Adjustable board size
  • Simulate over a thousand balls
  • Bar chart visualization of results
  • Educational tool for probability
  • Related to Pascal's Triangle

Originally conceived in 1894 by Galton, the board consists of countless balls traversing down through a maze of pins. At every pin, they have a single choice: go left or right. Although the possibilities seem limitless, a pattern soon emerges. But how does this really work? This app is a simulation of the famous Galton board and is intended for educational purposes. You can adjust the board size, and send over a thousand balls bouncing down the board. On iPad you can even run multiple simulations simultaneously with multiple windows. The results are visualized by a bar chart. The Galton Board is closely related to Pascal's Triangle, Newton's binomium and probability theory in general. For experiment fidelity and performance, the balls do not collide with each other. I hope this app helps people grasp chance at least a little bit better. Love the app, or have improvements/suggestions? Let me know!

Verdict

The call

The clearest difference is rating: Galton Board at 4.7 against Visual Trig Func's 1.0. Galton Board also leads on in-app purchases (none vs 1) and ads (none vs shown). Visual Trig Func's advantage is iOS requirement (14.0 vs 16.0). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Visual Trig Func sells 1 one-off in-app purchase. Galton Board asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Galton Board holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Galton Board has 43 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of Visual Trig Func's written reviews are positive against 60% of Galton Board's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Visual Trig Func ships an update every 5 months, Galton Board every 3 months. Both last shipped on June 1, 2026.
