never even worked

Does Not load. i never wrote app reviews but this one was so bad oml. i do my own work using Calculator84 (app for a scientific calculator, best one i’ve ever used) and i do my own problem and put it into this checker before i started so i could see if i got it right. i am by no mean fast at math. and still, when i went to look if i got the right answer, IT STILL HADNT LOAD. awful. i was on wi-fi! 5bars.

Doesn’t work offline, clunky UI and no privacy information

Even though the app is performing mathematical calculations any Apple device can easily solve using its own internal processing power, the app requires an internet connection to function at all. Similar apps do not have such a requirement.

The UI will randomly zoom in when you tap to enter a value, which can cut off part of the number pad. The number pad itself is oddly laid out, with 0-9 running left to right in two rows, rather than 9-1 running right to left in 3 rows with 0 and the decimal on a fourth row like a standard number pad on a calculator. The decimal seems almost hidden in the middle of a row of math symbols. The multiplication symbol is a dot rather than an X which is easily confused with the decimal. Results are sometimes given as equations rather than numbers seemingly at random. While you can then tap to view the results as numbers this brings up a chart which hides the graphic representation of the triangle.

Lastly, the app has not been updated since Apple began requiring developers to disclose what data they collect about you through the app, so users have no information about what data the developer is collecting through the app. That should be concerning to anyone who values their privacy.

Doesn’t work.

I get infinite loading whenever I ask it to calculate.

Response from developer

Sorry for your experience however, TrigCalc does not work offline.

Saved my math grade!!!

Download for trigonometry!! nearly saved my trigonometry grade!!! thank you!!!!!!

Amazing!

I don’t usually write reviews, but this app is amazing for a trigonometry level of math. It takes time to get used to it, but it definitely does the job that both photomath and mathaway can’t do! So great.

Response from developer

Thank you!

FAQ

What kind of calculations does this app perform?

This app specializes in trigonometry and geometry calculations. It supports solving for right and oblique triangles, circles, sectors, trigonometric identities, coterminal angles, supplementary angles, complementary angles, and trigonometric functions. It provides detailed, step-by-step solutions for each calculation.

How are the calculation results displayed?

Results are displayed using real mathematical notation, including radicals, exponents, fractions, and pi. For triangle calculations, you'll receive exact values for all sides, angles, the area, and the perimeter, along with a clear explanation of how each value was derived.

Is this app free to use?

The app is free to download and use, but it does contain advertisements. These ads are shown infrequently, only after a sum of calculations has been completed. There is an option to remove ads permanently for a one-time fee.

What is the cost to remove ads?

Ads can be removed from the application for a one-time fee of $5.99. This purchase will provide an ad-free experience for all future uses of the app.

What information is needed to calculate a right triangle?

To calculate a right triangle, you only need to provide two values, as long as one of them is a side length. The app will then compute all remaining sides, angles, area, and perimeter.
