Fastrack
A fasting tracker for the Apple Watch. I fast most days and wanted something that lived on my wrist: start a fast, glance at the ring, see what my body is doing, and log it without reaching for my phone.

The brief
This one does one thing. The logo doubles as the interface: the mark fills bottom-up as the fast runs, so it reads the second you raise your wrist. Pick a preset, watch it fill, and learn what your body is doing in each phase as the hours pass.
The mark
The thinking
Every fasting app I tried wanted an account, a subscription, and my phone in the loop. Fastrack is watch-only: no iPhone app, no accounts, no analytics, nothing leaves the device.
What it does
- Quick-start presets: 12:12, 13:11, 16:8, 18:6, 20:4, 24h, or a custom length. One tap starts the fast.
- Phase education: a live read on the metabolic phase you’re in, from digesting to deep ketosis, with the next milestone counting down.
- History and streaks: past fasts on a calendar, streaks, weekly trends.
- Reminders: phase and goal alerts, local notifications only.
- Weight log: optional, through Apple Health.
- Complications: a corner complication and a Smart Stack card with live fast status.
Design
Black, white and greys from the logo, on a black canvas with a little film grain. Four accent themes lay a single hue over that base. Secondary actions live below the fold, so the gauge always owns the screen.
