## What is Solve Right Triangle Pro?

The best app to calculate all quantities of a right triangle. You must enter some quantities like an angle and a length. The algorithm searches the formulas of the missing quantities, shows them and calculates the results.

The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition.

Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.

[ Content ]
- all important quantities for the right triangle
- formulas for all important quantities of a right triangle
- infographic to illustrate the topic
- search bar to find the desired quantity
- history function to save input
- detailed solution
- positive numbers, decimals and fractions are supported
- changeable decimal place
- no ads!

[ Usage ]
- there are several fields for entering the values ​​using a special keyboard
- if values are missing, all fields are highlighted in orange
- if values are conflicting or wrong (e.g. negative lengths), one affected field is highlighted in red
- every value must be positive
- the sum of alpha and beta must be 90°
- the sum of gamma must be 90°
- if a value is no number, it is highlighted in red
- the entries in the history can be deleted or sorted manually
- if you select an entry in the history, it will be loaded automatically for the calculation
- the entire history can be deleted by pressing a button
- solutions can be shared

### 1/5 — Don’t bother

*2025-12-26*

I’m convinced it doesn’t work. For a right triangle only two legs are required for calculations, but it repeatedly asked for more information. What, that it uses a 90°? And don’t bother to look for any help.

**Developer response:** Hello xswatts, thank you for reaching out. 

You are correct that only two values are required to start a calculation. γ is defined as the right angle (90°). Two values are sufficient (either two legs, or one leg and one angle). I have tested the scenario you described and was not able to reproduce any issue; the calculations work as expected.

For more guided experience I can recommend my app "Solving Pythagoras". This app calculates the third length from the other two: https://apps.apple.com/us/app/solving-pythagoras/id1270384222

Kind regards and a happy new year

### 1/5 — Rechtwinkliges Dreieck Pro

*2024-04-24*

Ich bereue es dafür Geld ausgegeben zu haben. Unglaublich schlecht. Werde ich löschen und still fluchen. Keine Empfehlung.

**Developer response:** Hallo RickoMa, tut mir leid, dass du eine schlechte Erfahrung mit eine meiner Apps gemacht hast. Ich möchte an der Stelle gern dazu einladen, dass du einmal schilderst, was genau dein Problem mit dieser App ist.

Dennoch - bereuen brauchst du gar nichts. In Deutschland gibt es ein Rückgaberecht, das dir erlaubt, innerhalb von glaube 14 Tagen dein Geld zurückzuverlangen. Mache gern Gebrauch davon:

## Version history (last 5 releases)

### 2.2.3 — 2026-08-14

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

Minor performance and UI fixes.

### 2.2.2 — 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)

### 2.2.1 — 2026-07-17

Maintenance update. Improving performance.

### 2.2.0 — 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.

### 2.1.10 — 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)
