Breathe with the tide.

A guided breathing coach with live heart rate. Inhale and the water rises, exhale and it falls. Finish a session, lay a stone.

Cairn turns a breathing exercise into a tide. Start a session and the waterline
rises while you inhale and falls while you exhale, uncovering a cairn of stones
on the shore — no counting, no timer to stare at, just a rhythm to follow. A
pulse on your wrist marks every phase change — a nudge to breathe in, a double
tick to hold, a longer pull to breathe out — so you can follow the rhythm with
your eyes closed.

While you breathe, the watch reads your heart rate every second. Afterwards you
get a calm score out of 100 built from completion, how far your heart rate came
down, how strongly it rose and fell with your breathing — real physiology,
respiratory sinus arrhythmia — and, on watches that deliver it, your actual
heart rate variability (RMSSD, the beat-to-beat detail behind true HRV). It is
the difference between a session you were present for and one you merely sat
through.

Finish a session and a stone is added to your cairn. Keep it up day after day
and the stack grows, badges unlock, and the progress screen shows where your
calm score and resting heart rate are heading over the last week and month —
with one line of coaching drawn from that history.

FEATURES
• Four patterns: Coherent (5.5 s in / 5.5 s out), Box, 4-7-8, and a Custom
  rhythm you set in half-second steps.
• Sessions of 1, 2, 3, 5, 10 or 15 minutes.
• Live heart rate, sampled every second, with a priming screen so the starting
  reading is a real baseline.
• A calm score from completion, heart-rate drop, breath-linked heart-rate
  swing and — where the watch supports it — real heart rate variability
  (RMSSD), with an honest fallback when there is no reading at all.
• A growing cairn, six badges, a personal best and your last 20 sessions.
• 7- and 30-day trends for calm score and resting heart rate, plus a coaching
  line.
• A distinct haptic pulse per breathing phase, and soft chimes at four volume
  levels; backlight, vibration and heart-rate display all switchable.
• Settings on the watch or from the phone (Clay).
• Made for the Pebble Time 2 (Emery) colour screen; works without the phone.
• Available in English, Nederlands, Français, Deutsch and Español, following
  your watch's system language.

Iron - Workout Companion for Pebble
Iron is a high-performance, open-source sports tracker for your Pebble smartwatch. Designed for runners and fitness enthusiasts, it tracks your real-time metrics and seamlessly bridges the gap between your Pebble and modern Android health ecosystems.
⚠️ Important Note: This watch app will not function at all unless used in combination with the Android companion app of "Iron". Also, while designed to support all Pebble platforms, it has not been fully tested on every single model. If you encounter any issues, your feedback is greatly appreciated!
📱 Companion App (Android)
To unlock the full potential of Iron, install the companion Android app from Google Play. The companion app runs a stable background service during your workout and securely syncs your Pebble's health data directly to Google Health Connect.
 Download on Google Play:

Staring at screens all day? Give your eyes the break they desperately need with the 20-20-20 rule! This simple and essential app automatically reminds you about the recommended 20-20-20 rule.

How it works?
When you open the app it immediately toggles its mode between active and inactive (nice in combination with quick launch). When active, every 20 minutes, your Pebble watch will gently vibrate 3-times. This is your cue to look at something 20 feet away (about 6 meters). You can stop after your pebble vibrates 3 times again (20 seconds).

A hub to view your daily health (stress, activity, sleep and nightly recovery) all in one spot. Designed to be reminiscent of the early Pebble health windows. It uses app glance to give you a quick sense of your overall status (out of 100) throughout the day.
