### 5/5 — 素晴らしい

*2025-05-09*

日本の山城をレーザー測距で測定するのに大変便利です
計算過程が示されているので補正や検算もできます
強いて言うなら入力した数値からグラフィカルに三角形が表示されると良いですね

**Developer response:** Update
こがらし2000様、三角形のグラフィカル表現が実装されましたのでお知らせいたします。アップデート（バージョン2.4.0）は数日中にリリース予定です。

## 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.

### 3.1.5 — 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)
