Numbr is a currency calculator, a notepad that understands your calculation. You can use notes with numbers alongside each other. And all your numbers are instantly calculated as you type. It's same as soulver/numi/etc, but for the Web.
Very convenient and feature rich, My only problem is that the URL changes with every new content you add so if I save a bookmark I have to make sure to save the updated link again to keep the new changes. In a way that is convenient too, since it is easier to share. But if there's a workaround for my issue that would be great
I love simple apps that don't want my information, my money, or my time. Delivers only value for free.
If you ever used Numi for macOS, you definitely want to try this one. This needs to be ported as an iOS/macOS app. I love it, and use it on daily basis.
