I'm very new to the ArcGIS suite of tools and I'm trying to find out if ArcGIS for Server is a requirement in order to use the Data Collector app. My preference would be to create an ArcGIS Online account and setup my maps there, then use Collector to capture points in the field on a mobile device (Offline) which would then be sync'd upon reconnect when not in the field or connected.
Is this functionality possible? I've been reading a lot about this type of scenario but there seems to be conflicting information about it. Keeping costs down would be the driving force behind this approach.
