This is such a highly valuable application that is open-source and free to download. Gotta download this application since this will be helpful when I go travelling to places or construction sites (as I am an engineer and just relocated to a place that I am not yet been able to familiarize).
Congratulations @mtimetraveller and I look forward to your upcoming hunts.
Yeah, I, myself, being a Civil Engineer, this app has been life-saving to me for numerous times.
Cheers.
