User Reviews

Trigonometry Help is praised for speed, simplicity, and accuracy, especially for right-triangle calculations used in carpentry, surveying, and fabrication. It auto-solves problems when given known angles/sides and offers decimal/angle-format options with on-screen triangle display. The main drawbacks are its restriction to right triangles and some UI quirks reported by users (e.g., missing clear/reset button and keypad symbol limitations). Overall, a highly useful tool with room for expansion to oblique triangles.

Pros

Very fast calculations and responsive performance.
Easy to use with a simple, clean interface.
Accurate results for right-triangle problems.
Highly useful across trades (carpentry, surveying, metal fabrication) for quick estimates and layouts.
Auto-solving when you input known angles and sides; adjustable decimal places and orientation display.

Cons

Limited to right triangles; no oblique triangle support (a recurring theme across reviews).
Some UI/UX limitations mentioned by users, including lack of a clear/reset button and keypad issues with degrees/minutes/seconds.

I use this for carpentry. It’s the perfect tool to quickly find the angles and lengths you need!

I’m a Surveyor and should be able to do this in my sleep but with all the new tools I have lost some basic skills. This app is very simple and gets me TGE answer I need in a snap.
