Your phone is across the room. You're on a call, in a meeting, or walking the dog. The timer needs to start, stop, or switch. You don't want to fish the phone out, unlock it, and dig for the right project.
You glance at your wrist instead. Two taps and the timer is running on the right project. Or you raise the watch and say "Hey Siri, start a timer for Acme."
That's what the Timesheet Apple Watch app is for. It's not a miniature dashboard. It's a controller for the moments when picking up your phone is the long way around.
What the Watch App Actually Does
The watch app keeps a small set of jobs and does them well:
- Start, pause, resume, and stop the active timer
- Change projects mid-day (stop, then start the next project, or ask Siri to switch)
- See the running task and today's total at a glance
- Trigger via Siri or a Shortcut
- Place a complication on your watch face for one-tap access
- Stay in sync with the iPhone app, including offline
It does not show full reports, edit historical entries, or generate invoices. Those still belong on the phone or the web.
Install and Pair
If the iPhone app is installed, the watch app installs alongside it for most users. If you don't see it:
- Open the Watch app on your iPhone
- Scroll down to Available Apps
- Find Timesheet and tap Install
- Wait a few seconds, the app appears on the watch home screen
The first time you open it on the watch, log in with the same account. The watch reuses the iPhone authorization, so you usually skip this step.
Starting a Timer From the Watch
- Open Timesheet on the watch
- Tap the project name to change the project if needed (recent projects show first)
- Tap Start
The entry is created with the current time as the start. When you stop later, the end time is filled in automatically. Every timer entry has a real start and end time, just like on the phone.
Tags, notes, and expenses are added on the iPhone; the watch keeps the start itself down to two taps.
Switching Projects Mid-Day
You're on Acme. A client call for Beta starts. Two ways to handle it:
Stop and Restart
- Tap Stop, the Acme entry closes with the current time
- Pick Beta, tap Start
Two separate entries with adjacent times.
Switch by Voice
Raise the wrist and say "Hey Siri, switch to Beta with Timesheet." The Switch Project shortcut stops the running timer and starts the new one in a single command.
Same result, no taps at all. The previous timer's end time and the new timer's start time are the same minute.
Complications: One-Tap From the Watch Face
Complications put Timesheet on your watch face so the timer is never more than a tap away.
Available Complications
- Timer status: Shows whether a timer is running, with the elapsed time
- Project timer: The active project's name and elapsed time, in the rectangular slot
- Today's hours: The day's working hours at a glance
- Quick launch: A small slot that opens the app in one tap
Adding a Complication
- Long-press the watch face
- Tap Edit
- Swipe to the Complications screen
- Tap a slot and choose Timesheet
- Pick which complication you want in that slot
- Press the digital crown to save
Smaller watch faces (Modular Compact, Infograph) get the most use. The complication updates regularly on its own, and tapping it drops you straight into the app.
Siri and Shortcuts on the Watch
Siri on the watch works against the same shortcuts you set on the iPhone. The phrases:
- "Hey Siri, start a Timesheet timer."
- "Hey Siri, stop the Timesheet timer."
- "Hey Siri, what's running in Timesheet?"
Custom Shortcuts are mirrored to the watch automatically when you create them on iOS. Open the Shortcuts app on the iPhone, build a flow ("Start timer on Acme frontend"), and it shows up on the watch under Shortcuts.
For more on this pattern, see the dedicated guide on Siri Shortcuts for Timesheet.
Offline Use and Sync
The watch handles short gaps in connectivity the same way the iPhone does:
- No iPhone nearby: The watch queues your taps and hands them to the iPhone the next time the two connect. The watch talks to its paired iPhone, not directly to the cloud.
- No internet on either device: Entries are stored locally. As soon as the iPhone reconnects, the cloud receives the data and updates flow back down.
Note: cloud sync requires a Plus plan or higher. On the free Basic plan, the watch still tracks and stores entries locally; the iPhone pulls them over Bluetooth the next time the two devices are together.
Common Patterns That Work Well
Keep a complication on your main face. Starting becomes: tap the slot, tap Start. Recent projects sit at the top of the picker, so the common case takes seconds.
Stop and restart back to back, or let Siri switch. Either way the day stays a clean sequence of adjacent entries with no gaps and no overlaps.
Don't use the watch for retroactive logging. The watch is for now. Past entries are easier to fix on the phone or the web, where you can see the day in context.
Keep the active complication. A glance at the wrist replaces opening the app. After a week, you stop thinking about logging.
Common Questions
Does the watch need the iPhone nearby? The watch talks to its paired iPhone, so the phone needs to be reachable for actions to be recorded. Brief gaps are fine; the watch queues your taps and hands them over once the connection is back.
Can I edit a time entry on the watch? Limited. You can stop a running entry early or extend it before stopping. Bigger edits belong on the iPhone or web app.
Does it drain the battery? The complication updates infrequently and the watch app sleeps when not on screen. Typical impact is one to two percent per day.
What if the watch and the phone disagree? The newest edit wins. Conflicts are extremely rare because only one timer can be active at a time.
Apple Watch Ultra differences? None worth noting. The Action Button can be bound to a Shortcut, which means a single physical press can start a timer. Set it up via Settings then Action Button then Shortcut.
Summary
- The watch is a controller for the active timer, not a dashboard
- Start, stop, and pause from the wrist; switch by stopping and restarting or via Siri
- Complications keep the timer one tap from the watch face
- Siri and Shortcuts work on the watch
- Offline tracking works on every plan; cloud sync needs Plus
Where to Go Next
- Automate time tracking with geofence, Wi-Fi, and NFC for hands-free starts before you even raise your wrist
- Use Siri Shortcuts to control Timesheet with one-line voice commands
- See your tracked time in a calendar view when you sit back down at the desk
