Great little app

Weights are listed as "mass." They're in there. This handy little app used to be a widget on dashboard. It has everything I need, more categories than I will probably ever use. Currency is updated daily. Pin it to the menu bar, the dock, or launch it with a hotkey combination of your choosing. It can stay on top of your other apps (convenient!) Decimal precision, font and color scheme are customizable.

This is a simple well-made handy little app. I only wish I could run multiple instances of it at the same time, one with one category, like lengths, another with mass, and a third with currency, all floating on top of my other apps so I would not have to switch categories so often. I got around that by installing another nearly identical app and run them both at the same time. ConvertIt is the better app.

Convenient, easy to use

Love this little utility. The ability to pin it is great, I love that it also still has the conversion from before if you close (collapse it) and re-open it, or as you toggle between different conversions it still has the type of conversion (e.g. GBP > USD) you had previously selected. It has a ton of conversions as well, and it fetches new currency conversions everyday. I do wish there were a way to favorite maybe 3-4 conversions as icons underneath the dropdown menu (like Temperature, Mass, Velocity, and Currency), which would be very useful when traveling. Highly recommended!

Very convenient, use it all the time in the kitchen for recipe conversion as an American living in Europe. The only thing I might change would be to make it a little more modifiable – there are many conversion options that I rarely or never use, and the list of options is long to scroll through. I'd like to be able to suggest the conversions I want to appear in the main list. On the other hand, the scope of the options is impressive, and it's very fun to use the app. Recommended, and I'm so glad I found this after we lost dashboard in the new OS!
