I entered 18° for the topmost angle, left side of 12, right side of 25 and solved the triangle. The answers were correct, but in the wrong place. The lower right angle was listed at 128.73° and the lower left angle listed at 33.27°. Those are the correct angles but reversed. Blatant error, please fix. ### 4/5 — Pay to remove Ad *2021-01-11, version 2.2* This app is simple and do the calculations without the need of a scientific cal, which work fine for me, especially when on the field. 4/5 star cause no option to pay to remove ads... ### 4/5 — The app don’t work anymore *2020-07-02, version 2.1* The app doesn’t work anymore it was good until it got updated. Please fixit is so useful ### 3/5 — Good but *2020-07-01, version 2.1* Can’t see what’s typed when in dark mode otherwise I like it. ### 3/5 — Cool app but it’s not perfect *2020-04-23, version 2.0* Typically this app will give you the correct results. However, I have found that it can be wrong in certain situations. This makes it unreliable; learn the laws and formulas to double check your answers when needed. ### 2/5 — Brian Cloherty *2020-01-31, version 2.0* Very basic app would be good for year 3 .. ### 5/5 — Awesome *2020-01-16, version 2.0* For some of my math questions it required square root, could you maybe and it? ### 5/5 — Fantastic *2018-05-18, version 2.0* Great app. Supper useful! One thing, it would be cool if you could rotate the triangles. Otherwise just a great app. The math is done very quickly. ### 4/5 — Works great. *2018-02-22, version 2.0* Works quite well, as some other people mentioned, decimals do indeed work. I give this a solid 4 out of 5. This would be a 5/5, however, the ads are sometimes distracting. Otherwise it does what it is meant to do. ### 5/5 — Love it because it is bare bones simple *2018-01-27, version 2.0* I just downloaded this app and I love it for quick and easy down and dirty triangle calculations. Decimals can be used for all entries. I download a few others after this app and they were deleted immediately after I tried them. ### 5/5 — Perfect *2018-01-24, version 2.0* Simple, fast, 100% accurate. Worth it. ### 4/5 — Love it; but limited *2017-10-28, version 2.0* I love this app, simple and easy to use. I use it in house construction. But it does not accommodate decimals. For instance, if I have a side of 12 1/2 inches, no way to input that. Likewise for angles; 22.5 degrees cannot be entered. ### 5/5 — Great little program! *2017-09-12, version 2.0* I needed a calculator to figure out some dimensions for my plot plan. Some of the areas were hard to work with due to vegetation, so the numbers had to be calculated. Quick work with this! ### 5/5 — Great *2017-01-24, version 1.1* Simple and easy to use ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2023-05-06, version 2.2* Imput side a = 7.03125, imput side b = 0.375. Calculator rounds to '7' and '0'. This leads me to look for settings, to eliminate rounding and - no settings that I can find. Ads, though. Right across the top, nice line of 'em. If you need this for anything serious, don't waste your time with this app. ### 1/5 — Not accurate *2023-02-05, version 2.2* Regular triangle calculations not correct! ### 1/5 — Ads *2021-04-28, version 2.2* Screw the ads ### 1/5 — Bad update *2020-07-01, version 2.1* After update app doesn’t work !!!!! Need fix asap !!!! ### 1/5 — Dropping the Comma *2017-10-23, version 2.0* Why does this app always drop the comma.... previously there was the option of a point . or a comma , i am an engineer and need to calculate very accurate size which are often in Microns..... Not Happy ### 1/5 — New update doesn't work *2017-08-04, version 2.0* On an older phone, on a regular triangle, can't input 3 sides because the base is hidden behind the "reset" and "calculate" buttons. ### 1/5 — NOT for engineers *2016-09-13, version 1.1* When using really small machining angles where it is supposed to calculate tan(alpha) = opposite over adjacent, where either opposite or adjacent is less than 1, the app fails and gives you 90 degrees instead of 89.5 degrees. Works with more equal sided triangles though. High school stuff... ### 1/5 — WRONG results! *2016-07-28, version 1.1* Gives WRONG values under "regular triangle". Enter 1,1,1 for bottom side, left angle and left side. You get top angle =1, right side =1, right corner=178. How do you mess up a programming 101 "triangle solver"? Have you bothered to test it before release? ### 1/5 — Gave this one the ol' try angle *2016-01-22, version 1.1* Super easy to use! This calculator is so funtastic that it even comes with all the wrong answers you could ask for, just like that friend who got you into trouble every day in junior high. ### 1/5 — Wrong values *2015-12-10, version 1.1* Returned wrong values for a side angle side calculation ## Most praised reviews (10 highest-rated) ### 5/5 — Outstanding App! *2026-01-13, version 2.2* Have been using this Trig Solver for years! Great to have for the machinist on the production floor! ### 5/5 — Simple and perfect *2021-11-04, version 2.2* couldn’t ask for more ### 5/5 — i love this app! *2021-04-02, version 2.2* i absolutely love this app. i was looking for a trigonometry calculator for school work and this was perfect! i wish you could rotate the triangle tho. This is a life saver and i truly recommend it, it’s really simple. ### 5/5 — This App Is Lit *2021-03-31, version 2.2* I love this app and it seriously is so helpful with my homework. If you struggle with trig then you need this ### 5/5 — Perfect tool *2021-03-24, version 2.2* Simple tool that’s great for the job site, no extra unneeded stuff to complicate matters. ### 5/5 — Bah *2021-03-08, version 2.2* I personally think it’s pretty nice. It has shown me the correct answers and the add is only on the top, it’s very out of my way. Just wish it would show the work too. ### 5/5 — Great app! *2020-04-09, version 2.0* I’m a machinist and use this app multiple times per day to do my job. Simple to use and accurate helps me eliminate those mathematical errors. ### 5/5 — Saving my grade *2020-04-07, version 2.0* This is the most useful app I’ve used for school so far. Whoever made this app thank you for saving my grade. ### 5/5 — Saved my grade *2020-04-07, version 2.0* Thank you developers of this app u saved my grade. ### 5/5 — Really helpful *2020-04-07, version 2.0* The app is simple to use and never makes any mistakes when it comes to math! One of the best triangle-solvers I’ve use😁 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
