  • (2022-09-01) Dagurui: Bonita simple y útil.
  • (2022-04-20) ゆっきー: とても使い易く便利。 しかし電卓を閉じても前回の計算結果が残っているので、毎回Cを押して消さなければならない。 電卓を閉じたら計算結果をクリアして欲しい。 Very easy and convenient to use. However, when I close the calculator, the result of the previous calculation is still there, so I have to press C to delete it each time. I would like the calculation results to be cleared when the calculator is closed.
  • (2022-02-15) Emily Liu: it's cool but i would like a delete button in case i mess up on calculating so i don't have to clear the whole thing.
  • (2022-01-19) Gia Kỳ Nguyễn: Ok
  • (2021-05-08) Rose Hanchar: The percentage key does not work.
  • (2021-03-17) Ethan Hu: There was a problem wth the square root though
  • (2020-10-16) Tony Connaghan: Sucks, can't add more than 3 rows at a time
  • (2020-08-20) Leo Lo: Just do it right for a simply calculator. I used this for years as a simply calculator under my Chrome Browser and also in my Chromebook. Good enough to do most of the daily calculation. If come with different color theme as a setting; that will be a perfect extension for me.
  • (2020-07-10) Giannis: Thanks, very good and without ads!!! ;)
  • (2019-08-25) Veerapoom Henganupan: Everything is good. Plain design. You can use keyboard key to type number. Only one thing that annoying me is the displayed number has not separated thousand amount by comma. When you calculate million amount, it is difficult to see what number is. It would be perfect if developer could add this feature.
  • (2019-04-25) Daniel Pryor: Love it!
  • (2019-04-09) Mysterious Wolf: I WILL admit that it was a bit convenient just sitting there. But it was very basic and simple, and was a little slow when typing the numbers. It could have some improvements. Don't really recommend
  • (2019-02-16) Shannon Baynes: I think that this extension is great, it is very efficient and easy to use. I really like the fact that you can use the keys on the key board and not just the mouse and in my case touchscreen. The only thing for me is that I would hope that in the future they added themes, right now it's a little plain for my taste.
  • (2018-11-23) simple
  • (2018-09-09) Clifford Poe: Overall function is great, however you are limited to 21 total characters so you run out of space with a longer series of numbers.
  • (2018-08-30) Isaac Bugalho: It just works. Perfect!
  • (2018-07-14) Eric Woodward: Perfectly simple and efficient.

  • (2022-04-02, v:1.7.9) Brandon Horst: Extension Removed from Shortcuts
    After the last update, the extension is no longer in the shortcut menu on Chrome with all my other extensions. It was very convenient to bring up the calculator with a button combination rather than having to click it every time. Is it possible to add back the functionality that allowed it to be activated with shortcut buttons?
  • (2021-05-26, v:1.7.8) Jacqueline Vonderau: Calculator won't open
    I downloaded the calculator so I can also use it on my desktop, but it won't launch. I have the web extension, but it disappears when I click off it.
  • (2021-05-08, v:1.7.8) Rose Hanchar: percentage key does not work
    percentage key multiplies the number instead of reducing it.
  • (2020-08-11, v:1.7.8) George King: Location of icon
    I down loaded your app, but can't find the icon to open it. It is not on the desktop or task bar. Any idea what I need to do to do to get it on the desktop?
  • (2020-06-13, v:1.7.8) Varun Traders: ESC not working
    only clicking in the main chrome window closes the calculator.
  • (2020-02-24, v:1.7.7) Honest E: Needs Cursor To Appear on the Right, Not the Left
    I love and use the extension often. Would be great to have the cursor appear on the right as I type, not the left. The reason this matters is when I make a mistake, I can't just backspace it until I move the cursor to the right of the equation from the left. If it's already at the right, I don't have to do that.
  • (2018-05-22, v:1.7.0) deleting it
    how do i delete it?
  • (2017-10-19, v:1.6.9) Ibrahim ONADJA: bonj
    affiché sur le bureau de l'ordinateur
  • (2017-10-15, v:1.6.8) David DeLisle: Copy/Paste
    Copy and Paste don't work with Chrome extension.
  • (2017-03-28, v:1.6.1) Chris Covington: .
    a school should not block a calculator or any app unless there is actually a reason other than they felt like it
  • (2017-03-28, v:1.6.1) Chris Covington: adding extension
    i cant add the extension it says that the school admin have blocked it , but its just a calculactor isnt it?
  • (2017-03-05, v:1.6.1) i dont see it as extension om my google bar
    hi, where can i start this app? unlike other extensions I don't see it at the right of my address bar. Thankx
  • (2017-02-08, v:1.6) CF Kinzer: size
    Please make this so that it can be enlarged like the Moffsoft calculator. There's also has a running tape which can be printed.
