A cleaner's day: start, pick a unit, tick, next unit

Start

She opens the address on her phone (saved to the home screen, it looks like an app) and signs in. Staff-role accounts land on Today and see nothing else in the navigation — no money, no clients, no settings. One button: I'm here. If you turned on GPS check-in, the phone takes a single position reading to confirm she is at the building; the platform stores on-site or the distance, and does not read her location again.

Today

The units on her rota, morning, afternoon, late, each with the number of tasks due. If the rota is empty she can pick any unit herself; the platform slots it by the clock. Tap a unit.

In the unit

Only the tasks due today, grouped by interval. Done is one tap and cannot be undone by her (a supervisor can). Used stock at the bottom: pick an item, a quantity, and it is deducted from the unit's supplies and recorded against the unit. Found something: a line of text and a photo raise a ticket for the manager — a cracked tile, a dripping tap — without leaving the page.

Next unit

When the list is done, one button moves her to the next unit on her day. When the day is done, the page says so. She signs out or just closes the phone; sessions on staff phones expire overnight.

What the manager sees from all this

Every tick with a time and name in the unit's history; the overdue matrix shrinking through the week; stock used per unit in inventory; tickets from things found; and, if check-in is on, who was on site when.
