### 4/5 — アイコンがダサい

*2026-05-05*

アイコンがダサいだけで、機能としては十分です。
関数電卓を謳うアプリに手を出す時点で物としての関数電卓を持っていることが前提だと思います
基本的にはお手持ちの関数電卓を叩いた方が間違いはありませんが補助的な意味では十二分に機能します。
とにかくアイコンがダサいというだけです。

### 4/5 — 機能向上希望

*2026-03-08*

dB計算が簡単に出来るとさらに嬉しい。

### 2/5 — Little but important changes need to be made

*2026-02-12, version 7.6.6*

I really like this app so I decided to upgrade from the free version, but there are some changes that need to be made to justify the price.
1) add dark app icon version that switches according to the system settings; 2) add the possibility to deactivate the “what’s new” screen when opening the app after a new firmware updates. Many people don’t care about the news (that, by the way, can be seen in the app store screen) and it is very annoying to receive them when you just need to use the calculator (especially because updates are very frequent); 3) have you tried to use the app with, let’s say, an iPhone X or later? The settings menu has white bars both in the upper (where the back button is) and lower part of the display while the page is entirely grey. 4) this app collects location? Come on! I don’t care how much it could be “generic” or for what “technical purposes” it is needed for but a calculator is a calculator and it must not collect location in any way! Users always prefer their location to not be tracked and if we’ll have to manually select (for example) which currency to use for conversion this will be a drawback we will be pleased to have…but don’t collect the location; 5) for the Italian users: to close the “what’s new” screen the blue button says “vicino” (that means “near”), to say “close” in Italian it is “CHIUDI” and if you want to say okay just write okay; 6) nothing else, I just want to say that this is a great app and I’ll give five stars when these little corrections will be made, thanks!

### 5/5 — 安定の使い勝手

*2025-08-25*

無料版に学生の頃からお世話になっており、社会人になっても大変お世話になっておりますので、感謝の意を込めて有料版を購入しました。
これからも宜しくお願いします。
欲を言えばポケコンみたいに横画面表示（左半分に計算表示で右半分入力部）でも使えたら嬉しいなと思っています。需要は少ないと思いますが、ご検討頂ければ幸いです。

### 2/5 — problem

*2025-08-23, version 7.6.6*

Hello, the calculator is fine. Most of the time, when typing, instead of adding the previous number to the right, it adds it to the left. When entering a number for multiplication and division, the numbers are not entered in order, and for example, the sum I want is like this. 2+3+5*6*7= This is how it comes in. 2+5*6*7+3= ????!!!!

### 5/5 — 超好用的計算機

*2025-07-14, version 7.6.3*

還在用手機內建計算器嗎？趕快換這款科學計算器吧！就算用免費的也甩好幾條街！

### 5/5 — 使いやすい

*2025-06-18*

式の修正とかが簡単で関数もほぼ網羅されている

### 4/5 — 必須アイテム

*2025-06-12*

30年以上前、高校生の時に学校で購入したSHARPのポケコンを今でも持っていましたが、持ち歩く訳にもいかず、iphoneの標準電卓よりも使い安い関数電卓を探していました。操作が直感的で使いやすく、エンジニアには必須アイテムです。

### 5/5 — Mulitline, Bracketed Calculator

*2025-06-02, version 7.6.3*

This calculator is very useful even for non Engineers.

Multiline means you can see past calculations conveniently w/o opening a panel or popup.

Scientific calculator means you can move cursor to edit your math expression; use brackets to specify order of operators.

Font size is also just right so you can fit long calculations on-screen

### 5/5 — とても便利

*2025-05-25*

こんな便利なアプリを作ってくれてありがとう。Mac OSでも使ってます。

### 5/5 — Great little app

*2025-05-23, version 7.6.3*

### 5/5 — 使いやすい

*2025-04-22*

シンプルかつ必要な機能が充実してる。
よければ計算式の誤字（末尾にマイナスを押してしまったとか）を自動で外して計算してもらえるとさらによくなるとおもいます！

### 1/5 — Paid app dont work

*2023-01-12, version 7.5.0*

Paid app not working keep saying JB detected

### 1/5 — Used to be great, but now has annoying bug

*2023-01-04, version 7.5.0*

This is the best calculator in the App Store for regular use that’s not emulating another calculator. Unfortunately the most recent release has an annoying bug. When you open the calculator, you’re screen is in the middle of the stack of previous equations rather than at the bottom. The cursor is at the bottom though. So you have to scroll all the way down before being able to see what you type. When this gets fixed, it’s back to five stars!

### 1/5 — iPad フローティングモード時に下部が隠れる

*2022-04-28, version 7.3.0*

I was happy using the app. Enough to decide to pay for ad-less version

The icon now says “PanecalPlus’

But each time i want to use it now it throws up the screen inviting me to pay or continue to see Ads. Obviously i am not going to pay again. But then i start seeing the ads

Grrr

It is very good app , but one thing that need your attention, which the language, when I use different language keyboard that works from right to left , and I go to this app, and start writing, it writes from right to left and to stop this I have to go to all the social app to switch texting to left to right, so please fix this problem, thank you very much.

### 5/5 — Imprescindible

*2026-05-23, version 7.6.6*

### 5/5 — 大満足です。

*2026-03-04*

広告ありの無料版で試してから購入しました。使いやすく反応もよい、機能は十分。良心的な価格。大変ありがたいです。

### 5/5 — 何年もお世話になってます

*2026-02-10*

何年もずっとお世話になっているのでいい加減にと有料版を購入しました。
自分は関数電卓としては使っていませんが、式の履歴が一画面上で見れて、式の再利用もできるのが気に入っています。
学生の頃なら関数機能も使っていたろうと思います。
普通に四則演算するだけならキーが画面下に寄っていて打ちやすいのも好きポイントです
