Why four apps
The timer you don't start is the session that never gets billed.
A freelancer’s billable hour is rarely at the desk it starts at.
You’re on your Mac when the client calls. You pick up the phone and walk into the kitchen. Forty minutes later you’re back at your desk, and the call is over, and nothing got logged. Or you’re on a train to a client meeting and a senior developer on your team DMs a question that needs a real answer — that’s the billable half-hour that gets lost because your laptop was in your bag.
Clockout exists on four surfaces for exactly this reason. The one you’re holding should be the one that captures the work. Start the call timer from your iPhone; finish it on the Mac. Let the Android widget sit next to your camera for client visits. Run the web app on the laptop your client loaned you. The billing trail doesn’t care which device you used — the workspace does the merging for you.
“Pick the surface that removes the most friction from starting the timer in the first place.”
