Hello! Wondering if anyone has a preferred website/app to use for check-ins, registration or attendance records for performances. Additionally, I'm looking for an app that engages audience members in short surveys. Ideally, we'd like to use the android tablets and just do the survey after the performance as they're leaving the theatre, but we also would like to send out a link to a survey via e-mail. What are the best apps/websites for these procedures?
