## Most critical reviews (10 lowest-rated)

### 1/5 — Not good

*2022-04-30*

This app is absolute rubbish. Completely inaccurate calculations do not purchase

### 1/5 — Units

*2020-12-13*

Units are in metric and not English Standard. Didn’t realize until after I purchased it.

### 1/5 — Very incorrect

*2020-10-28*

Tried to get answers for my homework and noticed the angles didn’t even add up to 180°! Very incorrect, do not waste your time!!!

### 1/5 — Wrong solutions for SSS

*2019-04-23*

Try a triangle with sides 16 20 31.  It gives an answer with a triangle that does not add to 180.  Just wrong programming.

### 1/5 — Only mm?

*2018-02-06*

Demo was basic but functional, was able to enter non metric values. After buying the version everything is metric, not what I want. Will contact my credit card company and contest the charge. It’s not about 0.99 but the principle.

### 1/5 — Metric only?

*2016-12-13*

When I tried the demo, the app was in feet. After I purchased the app it is only in meters.

### 1/5 — Disappointed

*2016-05-07*

How to change from mm to standard ?

### 2/5 — Wrong calculation

*2024-06-09, version 1.0.0*

The formula for the irregular triangle is wrong. If you give two known sides and an angle opposite to the unknown side, it will give you wrong angles. They don't even add up to 180.

### 2/5 — Problem

*2018-05-27, version 1.0.0*

The angles in my triangle don’t even add up to 180. What is this?

### 2/5 — Very rough. Ads with a forced timer. Only MM.

*2016-07-31*

I had a total of about sissy seconds in it when I'm forced to watch a static ad with a countdown timer. Forced to answer about purchasing the pro version. Rough and clunky. Only MM units.

## Most praised reviews (5 highest-rated)

### 5/5 — Amazing

*2020-06-05*

I was able to get a 100% on all of my homework assignments and super easy to use best app for trig

### 5/5 — brilliant

*2019-02-13, version 1.0.0*

all answers were spot on, THANKS!

### 4/5 — Units

*2025-01-27*

I like the app. Could additional units be added please? Such as U.S decimal feet and also angles in Degrees, Minutes, Seconds (to 4 decimal places) for surveying traverse checks. Thank you.

### 4/5 — Doesn’t have imperial but.....

*2018-02-21, version 1.0.0*

Just treat the measurements as units and it works just fine. Even if you use lengths of corn cobs👍🏻

### 3/5 — Please fix

*2021-03-22, version 1.0.0*

I’ve never got any of the angles to add up to 180° it’s always 150°-175° also add a feature to view history. Thanks
