Does the mobile staff app replace my website version? The ChamberMaster and MemberZone apps are for chamber and association staff to use while on the road. It does not replace the full product – rather it is a companion product giving your team access to information when remote. Apps are downloaded to your smartphone or mobile device and can access certain aspects of your ChamberMaster/MemberZone database. You can always use your full version of the software from your tablet, laptop or desktop by logging in through your browser software.
