Trigonometry Calculator

I've used this app to: 1. Calculate aircraft altitudes to fly a 3 degree glide slope on an instrument approach. Values used in planning the approach. 2. Countless carpentry calculations. 3. Land survey distances 4. Measure aircraft rudder deflection angles using laser beams. Set rudder limit stops with high accuracy. Building an aircraft. The adds are a nuisance but acceptable. I've used this app for 3+ years. This app is a valuable resource.

Great App, works exactly, makes calculation with a breeze and accurate. Though it would be nice where the sides of the angles input, create drop down to change from mm,cm,m,km and inches. Just like how we can convert from degrees to radians. Otherwise good be app, keep it up.

It's ok, however it would certainly better if it allowed us to do multiple angles/sides or change the ammount of factors on each calculation, and also if the image would change, as in my experience it did not. Overall ok for smaller equations but could certainly be better.

Very good, at first I thought it wasn't going to work and transforming my question to fit the information I was supposed to give was a bit confusing but the app did work and found my answer. I was really annoyed because I couldn't find the answer by myself, but this app saved me! The only thing is, if you don't have pro, it won't tell you the method to how it solved the problem. But still very good!

I am a casual user, but this app has been a big help in calculating figures related to stereoscopic cinematography. (That's just a fancy way of saying 3-D movies.) But, take it from me, this app is intuitive and helpful and well worth using.

Good for math class, but I am using to assist with carpentry and doesn't function very flexibly. Also, very, very secondarily, pop up adds (as opposed to banner ads) get in the way.

simple to calculate. It's enough to make me lazy. It would be nice to make a simple addition to the app. In italics add the formula used to give the answer in the background somewher

This app is worst because we need to find angle and side with proof this app show only area of right triangle (as a answer) we also can find the area of right triangke very easily pleaae rework on your app

Does exactly what it says on the tin. Clear in every respect. Although the adverts are non-intrusive, if I use it a lot I definitely will consider buying the PRO version.

Ads are understandable but frustrating when quick calculations are needed for work. Apart from that, works fine 👍

Alls well so far. A suggestion, after the user keys in the values, you calculate the remaining values for angle and side length. With the output values, could you render the triangle image with the same values ? It helps the user visualize what the triangle would look like

Pretty handy. Use it at least once a week. I do alotta building on the fly. No blue prints or drawings. Easy to figure out measurements and angles.

Spot On! Got this to help me work out stud lengths, board sizes & rafters when building a pitched roof timber framed extension. Easy to use & saved a lot of head scratching, 45years since I bought my first scientific calculator at school, wish this technology had been available then!

The math is wrong. 2 angles cant give you a answer you must have a distance to come up with an answer. This app doesnt work. I try to put in 90deg 60deg and then it wont let me put in a length . so your screwed

Tried to make a calculation and the app switched to and got stuck on an ad, making it completely worthless.

The most annoying ad gets played after a calculation. I expected something less intrusive. Uninstalled straight away.

Best app for trig calculation as far as I'm concerned. Haven't needed the advanced yet but sure I will eventually. Get it and see for yourself, I'm sure you'll agree.

I am a process piping designer/engineer. I have to use trig alot. Such as a rolling offset. Which I, up till now I could find an app that worked for my uses. Now I can ditch my ole Smoley's! Great app!

Very confusing instruction "Enter maximum of 2 values". What if i don't enter ANY values at all? App never worked. Finally got rid of it to save space.

Brilliant little app. Beautifully simple and un-cluttered. Just what you need on the go

Very easy to use. Helped to easily calculate somthing i needed to work on my sand casting patern making Add are not as distractin as in some other apps.

Very nice application, useful and easy to use. Many thanks to its Developer's Team.

Fantastic time saver. Use it almost every day in college. Don't have to worry about the formulas

I'm an old conventional machinst, and this app is ideal for all right angle trig functions I will ever need.

odd layout and the math goes bonkers ever once in a while but when it's wrong it us very obvious I think it's a decimal point glitch

Ads are fine, but ads in Chinese with no way of knowing what website they'll take you to is not okay.

Use it as a Boilermaker almost every day. great, simple app. Having it on hand is must.

This app helped me pass a test that i had taken 14 times before. Even after studying I couldnt get a 100. With this I past on first try.

Very nice app, I wanted to purchase this app, but I don't have clarity wheather the 175/- is one time payment or annually payment..

Works as described. It's definitely worth watching an ad.
