### 2/5 — why not include the angles?

*2025-04-11*

I wanted to know the angles of a triangle for a woodworking project, which is why I downloaded this app. Why on earth wouldn’t the designer include that in the answers?  Irritating.  $2 misspent.

**Developer response:** Hello Dandouchi, I am sorry for your bad experience. Unfortunately I am to late for a refunding. But for the next time you can do the following if you notice that a purchase is not what you expected:

"Request a refund for apps or content that you bought from Apple"
https://support.apple.com/en-us/118223

Do not hesitate to make use of it. It is not in my interest to have unhappy customers.

By the way - this app "Solving Pythagoras" focusses on using the theorem of Pythagorea. This only works with a, b and c. If you need all quantities of a right triangle (especially angles) you can use this app. It is free to use (unless you make the in-app purchase):

### 4/5 — Решить Пифагор

*2024-10-04*

Приложение работает, хотелось бы считать еще углы

**Developer response:** Здравствуйте, DN, мне жаль, что у вас остались неприятные впечатления от нашего приложения. К сожалению, мы не можем понять ваши отзывы, поскольку приложение отлично работает для других пользователей. Приложение также бесплатное. Чтобы мы могли внести улучшения, пожалуйста, опишите подробнее, что не работает. 
С уважением

Привет, DN. Спасибо за небольшое улучшение рейтинга. К сожалению, никакой дополнительной информации мы пока не получили.

Тем не менее, я рад сообщить, что в ближайшее время планируется обновление, которое внесет некоторые улучшения. Помимо прочего, планируется улучшение русского перевода.

Надеюсь, это сделает его более приятным в использовании. С уважением

Здравствуйте, я хотел бы иметь возможность ответить на отзыв пользователя на русском языке. Оно должно быть дружелюбным и вежливым. Пожалуйста, переведите мне:

Привет, ДМ. Я рад, что вы изменили свои отзывы в лучшую сторону.

Если я правильно понимаю, вам хотелось бы уметь вычислять углы в прямоугольном треугольнике. К сожалению, это приложение специализируется на теореме Пифагора.

Могу предложить вам еще одно приложение от нас. Это вычисляет все длины и углы прямоугольного треугольника:

Если вы хотите рассчитать другие типы треугольников, посетите нашу учетную запись разработчика. Мы предлагаем приложения для расчета всех размеров всех основных треугольников.

### 5/5 — Great app and simple to use

*2023-03-08*

This app great for solving Pythagorean theorem only and great to 90 degree layouts for outside deck project.

**Developer response:** Thank you very much for your positive feedback! By the way when you need some more quantities out of a right triangle you also may try this one: https://apps.apple.com/app/solve-right-triangle/id1567415770

### 3/5 — Great App

*2022-08-01, version 1.37*

The app is super but the advertising kills me dead-dead! There’s gotta be a better route to charging than just adverts or avarice? Also would damn appreciate NOT being asked to rate your app or I insist you get together with other app developers and insist on a better ratings system. You deserve it™

### 2/5 — Где не

**Developer response:** こんにちは！素晴らしいフィードバックをありがとうございます。敬具

### 3/5 — I give this a three

*2022-04-27*

Because I really don’t like the ads that will pop up but if they removed it this app will be a 4

**Developer response:** Hello! Thank you for your feedback. Ads are annoying. I understand that. But I think you still safe a lot of time and money using this app compared to get private lessons. Actually we get less than 1 Cent per user from ads. We keep searching for better options for monetization that are less annoying. I hope for your understanding. (You also could use the remove ads option or buy our PRO version)

### 5/5 — Fast and easy

### 1/5 — Чайки Вологодские

*2025-06-21*

Сразу же (не давая увидеть функционал) просят бабок. Удаляю. 😂 
Проще взять калькулятор и посчитать самому, чем открывать это чудо, смотреть рекламу да ещё и за бабки.

**Developer response:** Привет, gfugdhjcsjjcdf, ты прав, система работала некорректно. Приношу извинения. Она полностью переработана. Сторонняя реклама также убрана (из-за неё и возникали проблемы). Если что-то ещё не работает, пожалуйста, дай мне знать. Ваши «Вологодские чайки».

### 1/5 — Fix the problem

*2024-06-22, version 1.500*

Just updated app. Now it keeps telling me to purchase. Gets a-bit annoying. Hence why the rating one star.

### 1/5 — ********* Frustrated user *********

*2023-07-13*

I was looking for an easy app to calculate square corners of rooms and construction related problems.   The app asked me to sign up with a credit card to gain access, took me to a fraudulent website and tried to charge me $54.25 from SKMTCV.COM.  The bank caught it and stopped it.

**Developer response:** Neither does this app calculate square corners of rooms nor does it ask for a credit card. There is a mix-up. I'm sorry you fell victim to a scam. Kind regards

### 1/5 — бан

*2022-09-17*

бан

**Developer response:** Мне жаль, что наше приложение доставило вам неприятности. Вы можете описать, что у вас пошло не так. Искренне.

### 1/5 — Pythagoras

*2022-02-20, version 1.36*

Very limited app. 
You must know 2 sides of the right triangle. Doesn’t let you use a known angle with a side length to calculate the other two sides.

### 1/5 — I don’t understand how to use it

*2021-10-05, version 1.36*

idk how to use it but most ppls ig like it

### 1/5 — Trash

*2021-05-11*

Good for nothing

**Developer response:** Sorry to hear that. We appreciate when you describe the problems you had with this app. We still keep improving the quality. Either you could edit your feedback or send us a mail to contact@gslstudios.com. Thank you very much for your help!

### 1/5 — It is useless and trash

*2021-02-11, version 1.34*

Trash

### 1/5 — Your app 😂

*2020-04-08, version 1.31*

### 1/5 — Doesn’t calc

*2019-12-30, version 1.3*

Don’t know what’s wrong. Doesn’t calculate.
