The four Apple surfaces, and what each one is for
The Watch app is a full timer, not a remote: the tag list is on the watch, tapping one starts it and tapping it again stops it without touching your phone. A start carries its own timestamp from your wrist, so the entry begins at the moment you tapped rather than the moment your phone heard about it. That matters because the whole point of tracking from the wrist is the moments you do not have a phone in your hand: walking into a room, putting down a tool, picking up a call. Two honest limits: a stop is written when the phone receives it, not when you tapped it, and an action your phone cannot pick up within about half a minute is dropped rather than applied late — so this is for a phone that is nearby but not in your hand, not for a day out of range of it.
A watch face complication is the glanceable half of the same thing: it shows what is currently running, so the failure mode this app is really guarding against — a timer left on all night — is visible every time you check the time. On iPhone, a Live Activity puts the same running timer on the lock screen and, on the models that have one, in the Dynamic Island, so you do not unlock anything to see it. Home screen widgets are the fourth surface, and they are for starting rather than watching: tapping a tag on the widget opens the app straight into starting or stopping that tag, so it is one tap from the Home Screen instead of open-then-find-then-tap.
Together they are one product decision rather than four features: the cost of starting a timer, and the cost of noticing you left one running, both have to be near zero or people stop tracking within a week. None of these is behind Premium. Premium adds cloud sync and backup and nothing else.
Where an Apple Watch tracker is genuinely worse - honestly
Reading anything is the weak point. A watch screen is fine for one running timer and a list of tags; it is not where you review a week, correct a mistyped stop time or read a breakdown by tag. Those live on the iPhone, iPad, Mac or web version, and if you had hoped to do your whole timesheet from the wrist, you will be reaching for a bigger screen.
Editing history from the watch is not there. Adjusting a start time, splitting an entry or adding one you forgot are phone jobs. Correcting a forgotten entry after the fact is a separate skill; the guide on reconstructing untracked time on this site covers it.
And the honest caveat about the whole page: this is one indie app, first released in February 2026, with no App Store ratings yet as of 5 September 2026. The Watch app being free is a real difference from the paid-add-on pattern elsewhere, but "free" is not the same as "battle-tested across every watchOS version". If your working week depends on it, test it for a week before you rely on it.
