Not useable. No instruction. Deleted
Opened the app. The input screen indicated input of room dimensions in cm. I assumed a basic conversion scale of 1 foot to 1 cm, since no guidance was given. Screen reply was that my input was invalid. No other direction or instruction. The lack of guidance renders the app useless in my opinion.
Response from developer
Thank you for the honest feedback — you were absolutely right. Version 1.2.1 now supports feet/inches: the app defaults to ft/in for US users, with separate ft and in fields for each dimension, and clearer input examples. If you give it another try, I'd love to hear what you think.
