Soulver is a similar app for macOS, iOS, and iPadOS with shared documents in iCloud Drive. Check it out if you’re looking for something like this to go!

And! the parser and calculator engine is free to use for personal projects. It is an extremely pleasant SDK to use, and super powerful.

I love this model. Open source the library/SDK, then build your own paid application on top of it.

Soulver isn't open source. That repo is just a binary.

Soulver is no longer available for iOS and iPadOS. It's been pulled until version 3 comes along: https://twitter.com/soulver/status/1375548200833146884

Wow, I did not know this! Thanks for sharing.

Looks like there is a TestFlight link to get Soulver 2 for iOS and iPadOS if anyone is interested in it: https://twitter.com/soulver/status/1375368313774215171

I use Soulver 2 on my iPhone and iPad at least once a week and couldn't imagine going without it.

Soulver is so good. I use it almost every single day. It's just a great app and isn't that expensive. One of those apps I completely miss when it's not installed on a new device.

Another good one is http://calca.io, very like Soulver but also has simple graphing, runs on mac, iOS and Windows

Periodic reminder that iCloud Drive is not end to end encrypted, permitting both Apple and the US federal government to read all of your calculations at any time without a warrant.

Would love to see a web version

You want your calculator to be a web page?

Why not. I use Chrome to make quick calculations all the time. Just Ctrl+N and 1+1, and the answer is posted. Then Ctrl+W, and/or Alt+Tab to Sublime or whatever. Then I continue with my life :)

On macOS, Cmd+Space and just do calculations in the Spotlight search bar.

Just a heads up that everything typed into Spotlight is sent to Apple.

Do you have a source for this?

It's in the ToS, and there was a big hoo-haa over it at the time it was introduced. Eg: https://news.ycombinator.com/item?id=8473580

Aside from that, the most basic understanding of what Spotlight is reveals there is no other way for it to function other than to send the users input off-machine:

The user types in a value and results are returned related to that value, some, from online sources.

I also use Windoze, that's why I prefer the Chrome way.

I've made fcalc [0] for myself. It's much simpler and basically glorified `eval()`, but it's good enough for me.

AFAIK, Soulver is only for MacOS...

Nope, I have it on iOS.

But they've pulled the old version off the iOS store for the meantime before releasing the new version.
