### 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».

### 5/5 — 평가

*2025-04-21, version 2.04*

교육 시각적으로 좋음

### 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.

## Frequently asked questions about Pythagoras Calculator

### What does the Solving Pythagoras app do?

This app calculates the sides of a right-angled triangle using the Pythagorean theorem. You can input the values of two sides, and the app will automatically calculate the third side. It also stores all your calculations in a history for easy access and sharing.

### How do I calculate a triangle side?

To calculate a triangle side, simply enter the values for two of the edges (a, b, or c) into the designated fields. The app will then use the Pythagorean theorem to compute the value of the missing third edge. The input fields are highlighted to guide you if not enough values are entered.

### Is there a cost to use Solving Pythagoras?

The app is free to download and use, with an option to remove ads through an in-app purchase. This allows you to enjoy an ad-free experience for your calculations.

### What devices is Solving Pythagoras compatible with?

While specific OS versions are not detailed, the app is designed for mobile devices. It features a modified keyboard for input and allows navigation between input, solution, and history views via swiping and button touches.

### Can I save and share my calculations?

Yes, all calculations performed in the app are automatically saved in a history function. You can select entries from the history to load them for further calculation or editing, and the final solutions can be shared.

## Version history (last 5 releases)

### 3.2.3 — 2026-08-14

The latest release 'Least common multiple' is linked in the menu section now.

Minor performance and UI fixes.

### 3.2.2 — 2026-08-04

- the status bar on top is integrated into the current app design
- the app flow was improved (pop-up information was balanced)

### 3.2.1 — 2026-07-17

Maintenance update. Improving performance.

### 3.2.0 — 2026-06-19

Bringing all apps to the same security standard. Critical storage behaviour for solutions has been fixed.

By the way - I run many apps with different math topics. If you like this one: Check them out as well!

I always do my best to keep a high standard on my apps. If something does not meet the expectations, do not hesitate to contact me.

### 3.1.3 — 2026-06-06

There were some major fixes and adjustments for a more stable behaviour of the solution storage and loading. Therefore some database changes were made in the background. There are no performance losses and the functionality does not change. The background tasks are only done once within milliseconds. Following behaviour may occur (only temporary):
- stored calculations have to be tapped twice to load fully
- the order of the stored solutions may change

If there are some losses of solutions do not hesitate to contact me and tell me the number of lost solutions + affected app. I will find a solution for this.

Kind regards, Alex (the Dev)
