Hi @
Jane High,
if you are still looking - we use a system which is part of Quickbooks, called T Sheets. It allows individuals to log in and out of their location, select what sort of work they are doing, upload photos etc. It also tracks them, so that you can actually see where they are either live, or follow their movements for a day. Loads of other features too.
It may seem a bit ' Big Brother' but for our purposes (we have a lot of site teams, all over the UK), this allows us to check and monitor individual whereabouts.
Many different reports available too.
Every site team member has the app installed on their mobile device. It did require 'buy in' from everyone, but after a year or so of using this piece of software, we have found it invaluable.
