Great UX! Free! No ads!
My first ever and it’s for a Calculator. I never liked the stock Apple Calculator app. Just looking for one better, but didn’t want to pay for it and I found the Uno Calculator. It’s two face is creep and is easier to use, as the buttons are bigger and easier to press, especially on the iPhone. I was surprised to see only 110 comments but I guess a calculator is not something most people go looking for unless they need a scientific calculator or one more complex then a straightforward calculator. Speaking of which, this Calculator has all of them. And they’re free.

1+2*3
Hi the developer, I like this app and I have uesd it for several years. However, there is an issue I'm confused, when I input like 1+2*3, I think the answer should be 7, but this Calc gives 9. Could you adjust this calculate logic？
LuvIt! Keyboard Input is Enabled/MacOS 26
I really like this very efficient app on iPhone & iPad and had a difficult time finding the Mac app today, but finally located it. Yay! So apparently, at some point in time, keyboard input has been added. It seems to be a primary complaint in reviews I read and am pretty pleased that’s no longer an issue. I would have still used Uno, but prefer keyboard input for more complicated situations.
For me, I really like & use the history & memory panes, but if those are a deal breaker, from what I’ve seen, they can’t be hidden, yet!
I haven’t experimented with speech or dictation yet and notice there are other customizations I might try out, like font & color. Handoff is smooth between devices.
Thanks to the developers for making a fantastic multi-platform, basic calculator that just happens to be free. Much appreciated!

history
please don't delete history when i close the app.
Fantastic
Great calculator app hoping it continues to receive support and updates. My only complaint is it takes a bit longer to open than the official calculator app.
A better calculator app
This is a great calculator app - with many modes that you can switch between and loads of unit conversions. Based on the same underlying code as the Microsoft Windows Calculator app that was open sourced.
History Pane
I really like this app! The only thing, is I wish I could hide the history pane. No option to do so, and I can only drag & resize the window so small before it stops resizing, leaving the history pane there still. I thought I could hide it by dragging the side of the window to the left. The app on my MacBook looks just like the app on my iPhone if my iPhone is in landscape mode (shows history). When I turn my phone to portrait mode, it hides the history. How it looks on my iPhone in portrait mode is how I’d like to see it on my MacBook. Hoping this can be an easy fix for the developer. Thanx!

Best of the best, But!!!
Buttons disappear, while you using it on iPad.
The worst scientific calculator yet
One of the worst scientific calculators you can get. There’s no way to delete part of an equation and you can barely see what you’re even typing.
And still is the best calculator
No ads, no in-app purchases, just pure amazingness.
No calculator on iOS comes even close to this one. And now with iOS 18, I now have it on my control centre so that's nice.

Thank you!
Thank you for making a free simple calculator that supported slide over and side by side on the iPad! I appreciate it, I’m going to keep using it even with the new calculator app in iOS 18
Numerical Keypad incapable
I tried this app, but was unable to input from my Apple keyboard's numerical keypad. I will try again when this bug is resolved.
I never write reviews but this calc deserves a good one
I love this calculator. I’ve tried so many scientific calculators on iOS and they are all filled with adds. This calculator rolls a converter in and is free!? Thank you, you’re a saint for making this. Only one thing to add, give us an option to donate in the app. I appreciate that it’s free so much that I’d like to send a few bucks.

Un petit bijou!
Wow! Vraiment très bien. Les différents modes de conversions sont simples à utiliser et tellement pratiques!
La calculatrice que j’utilisais depuis toujours avait de plus en plus d’annonces. C’était insuportable!

No copy and paste is unfortunate
This is an excellent calculator but it's hampered by the fact that there isn't a copy and paste capability.
odd layout
iPad Air 3 here. Most people are righthanded, so it's little odd seeing uno's keys on the left of the screen, with your hand obscuring the tape as you type.
I think buttons on the right should be the default in a preference setting.

I love this calculator
If this calculator app ever goes I away I will genuinely be upset. If there’s one thing I hate about iPhones it’s the calculator. This app has changed my life. Best calculator out there. 10000/5 stars. Thank you.
No ARM support, slow
What's the point of showcasing UNO Platform portability solution for apps, if it doesn't support Apple silicon?
One annoying problem on ipad
Solid calculator app on my iPad. However, when buttons are pressed with an apple pencil, it turns dark, making the buttons like the equal button blend perfectly into the background, making it invisible. Pressing them with my finger doesn’t trigger this. Hope you guys fix this problem because it is getting annoying.

Just what I was looking for
Nice, clean interface. Love the history function. Only improvement I could suggest is to move the calculator buttons to the right and the history to the left. It’s more intuitive for right handed users. Or provide an option to reverse the presentation.
