What’s New

Version 1.3.5

Do you know that moment when you realize that while you fixed one bug, you missed another one? Well, that's how I feel right now.

Here's the fun part; the calculations have always been correct. BUT, the UI didn't always update instantly as quickly as your finger could hit the keys on your keyboard and that just isn't good enough for me.

Anyways, I've solved the problem (for good), and apologize (again) for my obvious lack of perfection.

On the plus side, this app is now even more awesome than it was before! That, and I feel kinda silly for fixing one bug and completely missing the inverse of the bug.

Insanely Useful

Don't let the age fool you. Runs perfectly on Mojave. It's simple and all it needs to be.

No nonsense - does what it’s supposed to!

Simple, lightweight app. Its not the prettiest but its the first I grab when I need numbers to scale! More than once I was glad to have this handy.
