I’ve used the Calculator app on the iPhone for as long as I’ve had a smartphone and I think on the computer, it’s a weird thing that’s been missing for a long time. Recently, Apple brought the Calculator app to Mac but I don’t think it’s as useful as I want it to be so I recently discovered an app called Numi.
It’s a super simple app that just works and the best part about it is that it supports setting variables and making conversions between many units extremely easy.
Here’s an example of a time difference comparsion:
Using the correct divisors is amazing in this app. So on mac you can use / or alt + / to type out ÷, Numi handles both of these the same way.
