Activity

**In progress**

Saved on watch

· · ·

**Companion app**

## Tools & technologies

-   watchOS or Wear OS
-   Platform sensor APIs
-   Companion connectivity
-   Native UI

## Small screens need smaller decisions.

### Quick actions

Confirm a task or record an event without opening the phone app.

### Activity experiences

Present permitted sensor information and session progress on a small screen.

### Companion apps

Keep selected watch and phone state consistent across disconnections.

## Complete a timed activity

Capability Example

A wearer starts a short activity while the phone is out of range.

### Start

### Finish

### Sync

Illustrative data. Nothing is sent to an external system.

Example workspace 1 / 3

### Active session

-   Session: W-17
-   Timer started on watch
-   Phone: disconnected

Save the session locally and show its timer.

### Completion record

-   Session ended once
-   Screen can sleep
-   Result saved on watch

Record completion once, even if the screen sleeps.

### Companion record

-   Phone reconnected
-   W-17 synchronized
-   Duplicate completion ignored

Transfer the completed session to the phone when connected.

The same completed activity in watch and phone history without duplicate entries.

Follow the record through the next step

## Watch, companion and synchronization behavior.

-   **Wearable interaction prototype**
-   **Watch and companion code**

-   **Battery and sync test report**
-   **Permission and release guide**

## Design around power and attention.

### Hardware and permissions

Available sensors and background behavior vary by device and OS.

### Product claims

Wellness tracking does not establish clinical accuracy; any medical use needs its own validation and review.

## Questions before we start.

### Does the wearable need a companion phone app?

That depends on account setup, network availability and the watch platform. We define standalone and companion behavior separately.

### Can all phone features move to the watch?

No. The useful watch scope is usually a small set of brief interactions, with deeper tasks left on the phone.
