### 4/5 — Love design, Widget could be improved

*2024-05-23*

I got this app bc of the widget function. I love it so much but it’s pretty annoying that when I’m using the widget, the app opens. Is there a way to change that with the next update pls

### 4/5 — A great App missing one vital item - iCloud

*2024-05-16*

I love this app, simple but sturdy enough to retain a history. 
Unfortunately the history is only of use to one device, it is not passed on to other devices ie iPhone/iPad/Watch. What it needs is iCloud support and a watch app.
Give me these and I would gladly pay.

### 4/5 — Funktioniert, aber…

*2024-02-20*

Die App funktioniert und tut soweit was sie soll. Allerdings ist das Widget ohne Update nicht wirklich aus dem Sperrbildschirm aus nutzbar. Dieses öffnet unmittelbar nach der Eingabe eines Wertes die App. Kann der Entwickler dies bitte beheben? Dann gibt es auch ohne Probleme 5 Sterne von mir. Vielen Dank

**Developer response:** Hallo Antexus, es tut mir leid für die Unannehmlichkeiten, die Sie mit der Widget-Funktionalität auf dem Sperrbildschirm haben. Könnten Sie bitte versuchen, das Widget vom Startbildschirm aus zu verwenden und mir mitzuteilen, ob es dort ordnungsgemäß funktioniert?

Darüber hinaus wäre es äußerst hilfreich, wenn Sie uns ein Video zur Veranschaulichung des Problems an Developer@supagarn-pa.com senden könnten. Dadurch kann ich das Problem besser verstehen und eine Lösung beschleunigen.

### 4/5 — Could be cooler

*2024-01-26*

It would be cooler if I could change the color of the background

### 3/5 — Usability issues

*2024-01-26*

The calculator looks good and functions well, but the widget is barely usable. Click too many times too fast and the calculator opens. This defeats the purpose of the widget and my main reason for buying it. This is a problem and needs fixed with an option to select different click intervals or something.

### 4/5 — Good but response is slow on widget

*2024-01-20*

Good but response is slow on widget. The app is fine but the widget is almost unusable.

### 3/5 — Room for improvement

*2024-01-19*

This widget is a great concept. The calculator looks nice. I bought it to be used mainly for the widget but there are some issues.

1: when doing calculations from the widget, it lags a bit so it sort of defeats the purpose to using it as a widget. Is there a way to make it snappier and faster?

2: when using as the widget, it does not provide any haptic feedback, please add it if possible.

3: if I am pressing the numbers on the widget too fast, it automatically opens the full app instead. I would like the widget to stay as a widget and not open the full app.

### 4/5 — Please add customization function

*2023-12-11*

Most calculator apps I have used(including the default ios app) have the number ‘0‘ come before the decimal point. Please add the customization feature to change the placement of the number ‘0’ according to the user’s preference. Best would be in the following order:  0  .  +/-

### 4/5 — Customization needed

*2023-12-03*

A lot of the calculator apps I have used in the past had the placement of the ‘0’ come before the ‘.’ and ‘+/-‘. When I am using this app, I find myself unconsciously pressing ‘+/-‘ when intending to press ‘0’. If customization is allowed on this app, this will make it an A+ app and appeal to more users. I suggest customizing so that the bottom buttons come in the following order: 0, . , +/- which is the order of frequent usage.

### 4/5 — Handy app/widget with one flaw

*2023-10-26*

I love this caulculator… looks nice, and is not loaded with a bunch of scientific calculator features that I’ll never use.  The widget feature, however, is the main reason I purchased it, but there’s a usability problem with it… if you tap a number multiple times in rapid succession in the widget, it opens the app.  In other words, if you are trying to calculate 44x7, chances are when you hit that second 4, it’s going to open the app (unless you deliberately wait a half second or so between taps).  Perhaps this is intended, but it makes the widget very frustrating to use.

### 3/5 — 위젯으로 계산하다보면…

*2023-10-22*

조금만 빨리치면 바로 앱으로 들어가버리네요 
그리고 반박자정도 늦게 떠요 숫자가 ㅠㅠ

### 1/5 — Widget is not working as of Sep 22, 2024

*2024-09-22*

Please fix

**Developer response:** I apologize for the inconvenience you're experiencing. Sometimes, after a new iOS or app update, certain features like widgets can stop working. To resolve this, I recommend trying the following steps:

1. Remove the widget from your home screen.
2. Restart your phone to refresh the system.
3. Add the widget back to your home screen.

If the problem persists after following these steps, it may be due to a deeper compatibility issue. In that case, please feel free to contact me directly at developer@supagarn-pa.com, and I’ll be happy to assist you further and investigate the issue. Thank you for your patience!

### 1/5 — Widget Doesn’t work with stack

*2024-02-22*

The widget doesn’t work if we add as a stack. Especially the large one. This was my only reason to buy the app

### 1/5 — The widget doesn’t work

*2023-11-30*

The widget doesn’t work

**Developer response:** Hi Fastwalking, I apologize for the inconvenience. If you're unable to see the Calcullo widget in the widget list or it doesn’t work, might I kindly suggest restarting your device?

If the problem continues, please don't hesitate to let me know at developer@supagarn-pa.com

Thank you for your patience and understanding.

### 1/5 — Widget doesn’t work on iOS 17.0.2

*2023-10-03*

On iOS 17.0.2, whenever you use the widget, it will suddenly jump into the main screen of the full app unexpectedly. This even happens within the main app, if you try to report a bug. Not usable in this state.

### 2/5 — Too slow and buggy.

*2023-11-19*

When typing, there’s an input lag which is annoying. Also, every 3-4 taps (sometimes less) it opens the full screen app, making it pointless to have this as an “interactive widget”.

### 2/5 — Handy app/widget with one flaw

*2023-11-16*

I love this caulculator… looks nice, and is not loaded with a bunch of scientific calculator features that I’ll never use. The widget feature, however, is the main reason I purchased it, but there’s a usability problem with it… if you tap a number multiple times in rapid succession in the widget, it opens the app. In other words, if you are trying to calculate 44x7, chances are when you hit that second 4, it’s going to open the app (unless you deliberately wait a half second or so between taps). Perhaps this is intended, but it makes the widget very frustrating to use.

There have been several updates to the app since I originally posted this review, and I excitedly recheck the functionality each time, hoping it’s been fixed, but so far it hasn’t.  I’m likely going to uninstall it, and I regret the purchase.

### 2/5 — Clean and efficient app but with a fatal flaw

*2023-11-09*

This is a clean looking and efficient app but with a fatal flaw: Divide 1 by 3 and you will get an answer that omits the first digits of the answer. Instead of getting “0.3333333333…”, you get “…333333333333…” which is basically useless. Needs fixing.

### 2/5 — Widget not working

*2023-10-25*

I downloaded this app off of an article that I was reading on Apple News+. I have deleted it and downloaded it. Several times the widget is blank. I cannot get it to work on my home screen please fix overall that seems like a really cool widget which is why I downloaded it in the first place and paid the $.99. Thank you.

**Developer response:** Hi Fizzy we, I apologize for the inconvenience. If you're unable to see the Calcullo widget in the widget list, might I kindly suggest restarting your device?

If the problem continues, please don't hesitate to let me know at developer@supagarn-pa.com

Thank you for your patience and understanding.

### 3/5 — Was great sadly stopped working

*2026-01-15*

Was great but the widget stopped working a couple of weeks ago

### 3/5 — Erweiterte Funktionen fehlen

*2024-04-18*

Die App bietet ein sauberes Design und einfache Bedienung, aber sie lässt erweiterte mathematische Funktionen vermissen. Sie ist ausreichend für grundlegende Berechnungen, aber für komplexere mathematische Aufgaben ist sie nicht geeignet. Hoffentlich werden diese Funktionen in zukünftigen Updates berücksichtigt.

### 5/5 — Great App /w iOS18 Widget

*2024-09-22*

downloaded this app as i needed a calculator widget in iOS 18 as my go-to app of several years was no longer providing a widget in iOS 18. Calcullo is a perfect replacement and multifunctional. thanks you developer.

### 5/5 — Merci Beaucoup

*2024-05-31*

Nothing to say but it's done very well.  This app/widgett carries an air of class and refined simplicity.

### 5/5 — Pro tip

*2024-05-27*

Instead of using the 17+ Widget, there’s a legacy one accessible via the “Personalize” menu in the Today View. This one doesn’t have the interactive widget typical delay.

### 5/5 — Amazing!

*2024-04-15*

I just started using this calculator and so far it's been amazing! I use it for work purposes and I Love The convenient widget feature and it allows you to calculate big numbers!

### 5/5 — Please include a calculations in “Trillions”

*2024-03-13*

Great app, excellent UI, widget, etc… very clean interface- but could you please extend the number of decimals to more than 10, and expand functionality to include calculation of trillions.

### 5/5 — Clean and efficient app but with a fatal flaw

*2023-11-17*

This is a clean looking and efficient app but with a fatal flaw: Divide 1 by 3 and you will get an answer that omits the first digits of the answer. Instead of getting “0.3333333333…”, you get “…333333333333…” which is basically useless. Needs fixing.

————————————————————————-

The developer fixed the issue right away.  I couldn’t be happier with their response.  Now the app is clean-looking, effective and perfect!

**Developer response:** Hi Dan Bahk, I apologize for the inconvenience you've experienced. I'm delighted to inform you that I have already released a new version of the app that addresses this problem. You can update the app to enjoy the improved functionality. Your feedback is valuable, and I appreciate your support.

### 4/5 — widget’s response time is way too slow

*2024-11-17*

The app’s design is clean and well-made, but the widget’s response time is way too slow. When I press a number button, it takes about 0.5 seconds to respond. Please fix this issue! 😭😭😭

### 4/5 — Gute App mit Luft nach oben

*2024-11-15*

Die App funktioniert prima. Mir reichen die Standardfunktionen. Allerdings funktioniert das Widget im Sperrbildschirm nicht. Es zeigt keinerlei Eingaben. Auf den anderen Bildschirmen geht es. Daher nur 4 Sterne. Bitte noch korrigieren.

### 4/5 — Slight delay when tapping inside the widget

*2024-09-29*

The app works really well, but when pressing the numbers inside the widget, there is about a half a second delay between presses. Inside the actual app it’s absolutely fine. This is on an iPhone 16 Pro Max and it was on an iPhone 15 Pro Max running iOS 18.0 and iOS 18.1 beta five.

### 4/5 — Was 5 star

*2024-09-23*

This was a far better calculator than the default one, but with the ios18 upgrade, Calcullo could use some improvements to keep up. Eg, currency/measurement converter, equations support, and lockscreen widgets.
