Apple Watch

The Watch app records routes with its own GPS session — no iPhone required — and syncs them back automatically. Complications keep today's stats on your watch face.

An independent recorder

The iso.me Watch app isn't a remote control — it's a full tracker with its own GPS session. It installs and runs on its own (no iPhone required nearby), records routes with fitness-grade accuracy, and queues everything offline until it can sync.

On the watch

Watch-recorded distance uses sensible heuristics: fixes must be accurate (≤ 100 m), movement under 10 m doesn't accumulate, and a new “visit” is counted after about 100 m of displacement. Day counters roll over automatically at local midnight.

Sync back to the iPhone

Recorded points are queued durably on the watch and transferred automatically — every 25 points, at session start and end, and whenever the phone is reachable — then merged into your iPhone history. The merge is idempotent: re-syncing never duplicates anything, and the phone reverse-geocodes the imported visits so they get proper names. Recording works fully offline; sync catches up whenever it can.

Complications

Four watch-face families show today's status at a glance:

FamilyShows
CircularTracking status icon + today's visit count.
RectangularStatus, current place, visits, distance, auto-off time remaining.
InlineOne line: “N visits • distance” or “Tracking Off”.
CornerStatus icon with a visit-count label.

Complication data refreshes about every 5 minutes while tracking and 15 minutes otherwise, and immediately after each sync.

Units: the watch follows your iPhone's Metric / US setting where available; on its own it derives units from the watch's locale.
