Really handy app for quick scale conversions! The interface is simple and easy to use, and it saves me a lot of time when working on model projects. Perfect for anyone into architecture, design, or scale modeling

Very simplistic app. Just one screen. Too simplistic actually. It would be nice if it had more advanced features such as giving you real fractions of an inch instead of just a decimal equivalent.

It's pretty simple. It's nice for a quick conversion. Would be better with more decimal places. In 1:350 scale it gives the same answer for 2" through 5" of 0.01
