From what I can tell the app looks great so of course when I attempt to register it refuses to accept or doesn't recognize my 10 digit phone number and tells me to put another 10 digit phone number in. (Update 1/17/16) only a few days after my issue I update the app and it is resolved the app works very well for what I need it. Two thumbs up, 5 stars.
Samsung note 4. Won't accept phone number and won't register. Don't waste your time. Why must I register anyway?
This app is incredible. Takes almost all the functionality of safespec offline and on your phone. I can do hazard scenarios, product selection, and look up permeation data on garments all without a data connection!
It never worked after installing. The app kept saying to restart. Restart after restart yielded nothing.
