What's New in Uno Calculator

Performance and stability fixes

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!

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.
