Smena

A concept app for shift teams: the rota, shift swaps and hours worked, instead of a photo of a spreadsheet in a group chat.

Format Concept: idea, flow, screens
Platform Android, Jetpack Compose
Design Material 3
For whom A chain of 2–10 sites, 15–60 people

The problem

Where people work shifts, the rota hangs in a group chat as a photo of a spreadsheet, and cover is found by posting "who can take my Saturday?" among forty other messages.

Three problems grow out of that: people forget their own shift, a swap agreement is recorded nowhere, and pay arrives as a single figure with no explanation — so every month ends in an argument.


What is designed
01

Your month on one screen

Colour carries the shift type: morning, evening, night. The next shift is pulled out as a card — time, site and who you are working with. The one after it sits below.

02

A swap board

A colleague posts a shift with a reason, anyone takes it in one tap. Urgent ones are marked. Finding cover stops being a conversation.

03

Hours follow whoever showed up

After a swap the hours move to the person who actually worked. This is exactly where trust in any informal arrangement breaks: one person works, another stays on the timesheet.

04

You can see how the figure adds up

Day and night hours, swaps, deductions — itemised. The shift worker's main question is answered before it is asked.


What would be hard
01

A swap is a deal

Taking it is not enough: it needs confirmation from both people and the manager. Otherwise someone claims a shift, does not turn up, and nobody carries theresponsibility.

02

Hours are counted differently everywhere

Night, holiday and overtime rates are not a formula but configurable rules: labour law plus an internal policy that differs at every chain.

03

Not a payslip

The app shows an indicative figure and says so plainly. The moment it looks like an accounting document, the first discrepancy becomes a dispute.

What comes first

The rota and a "your shift is tomorrow" notification. That closes the first problem immediately and gives a reason to open the app daily. Swaps and pay follow second and third.
