## What is Calculator HD (for iPad)?

Proudly presenting the grand release of "Calculator HD" version 4.0! Support for Split Screen is finally here!

In this brand-new version, you can enjoy more convenient operations through Split Screen and Side Over. You can delete accidental input errors by swiping left or right, and you can also copy calculation results or paste calculation data between different apps.

There are countless calculator products on the app market, but none achieve such perfection. Optimized for the latest version of iOS, "Calculator HD" brings you a perfect blend of simplicity and ease of use like never before. In the vertical basic mode, you will never accidentally press those large, finger-friendly keys; while the horizontal scientific mode provides you with all the functions you need for your daily calculations—those functions you will actually use, not just decorative embellishments.

"Calculator HD" is the perfect replacement for the iPhone calculator, only bigger, clearer, and easier to use. You don't need to spend any time learning how to use it because you are already very familiar with its operation.

Happy calculating!

### 5/5 — 使いやすい

*2025-12-05, version 4.3*

Merci au Développeur!

### 5/5 — Sehr gut

### 4/5 — 文字が小さくなった？！

*2024-02-13, version 4.1*

iPhoneと同じ感覚で使えるので重宝しています。
ところで、2024/02/13にアップデートしたら全体的に数字が小さくなりましたよね？！？！
線も細いので正直ずっと使っていると見づらくなってきます。
iPadの大きさならではでもう少し枡に対して数字の大きさと線の太さを大きく太くしていただけませんでしょうか？

### 5/5 — perfektes Design

*2024-02-09, version 4.1*

Perfekt in Design und Fuktion!

### 5/5 — Самый лучший для iPad

*2024-02-09, version 4.1*

Лучший калькулятор стал еще лучше!

### 2/5 — cyfry

*2022-10-30, version 3.1*

Przy przestawieniu Ipada z poziomu do pionu, nr wyświetlają się całe znaki

### 1/5 — Funktioniert nicht richtig beim Kopieren

*2022-05-19, version 3.1*

Hat man einen Betrag errechnet, und „kopiert“ ihn um ihn dann zum Beispiel in Numbers einzufügen, macht der Rechner aus einem Komma leider einen Punkt. Also hat man 82,25 und kopiert diesen Betrag wird beim einfügen dann 8.225 
Das ist nicht schön und unbrauchbar….

### 2/5 — Rendering issue on moving from Scientific mode to Base mode.

*2022-04-28, version 3.1*

As title, buttons don’t render properly. Really basic failure and major experience issue which implies zero testing. Running (almost) on latest iPad Mini.
