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
- Start / Stop — one button; permission is requested on first start.
- Status card — live elapsed timer (plus remaining auto-stop time when one is set from the phone).
- Today card — visits, distance, and points recorded today, with a Reset today button for a fresh start.
- Location card — current coordinates and last update time.
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:
| Family | Shows |
|---|---|
| Circular | Tracking status icon + today's visit count. |
| Rectangular | Status, current place, visits, distance, auto-off time remaining. |
| Inline | One line: “N visits • distance” or “Tracking Off”. |
| Corner | Status 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.
