Does anyone have a recommendation for a software package to use for visitor sign in, GMP compliance and safety/evacuation information? I'm looking for something to purchase that we can use on our ipads for visitors to watch a video, review our GMP guidelines, PPE, etc and then sign in. I would like for the system to keep track of all visitors and those who have review the information on an annual basis. Someone recommended Envoy, but I'm wondering if anyone has any other recommendations. TIA!
