Your team should install one app, not choose between several. Everything is now in a single app, with each person seeing the parts they use.
Everything in One Place
Jobs, work orders, tasks, order detail, inventory and the WhatsApp inbox are all in the same app, with an app switcher between areas.
Each Person Sees Their Own
What each person sees is driven by their role and the pages assigned to them, so one app does not mean one cluttered screen.
One Thing to Install and Update
A single app means one install for a new hire and one update when something ships.
