Sentinel is an experimental, on-watch wellness monitor for Pebble Time 2.

Enable background monitoring once, then keep using your normal watchface. Sentinel attempts short overnight heart-rate and optical pulse-interval recordings, rejects unsuitable motion-contaminated data, and builds a personal baseline over qualifying nights.

Features:
- On-watch dashboard with monitoring status, heart rate, RMSSD when available, sample freshness and calibration progress.
- Recent-night heart-rate and HRV history, with missing measurements shown as gaps.
- Configurable night hours, recording cadence, window duration and notification settings.
- Experimental strain notices for sustained changes from your own baseline. The background worker opens Sentinel once for an eligible episode; the app vibrates unless Quiet Time is active. Muted/silent notices remain in the app. This is not a native phone push notification.
- No account, network connection or maintainer server required by Sentinel. Measurements stay on the watch. Any optional Pebble Health platform synchronization is controlled by PebbleOS, not this app.

IMPORTANT: This is an early experimental release, not a medical device. It cannot diagnose illness, estimate your probability of infection, rule illness out or replace medical advice. Poor sleep, exercise, alcohol, stress and other factors can change the readings. Real-watch HRV quality, overnight coverage and battery impact have not yet been validated. The worker has limited memory headroom; this release is for testing, not dependable health surveillance.

Current Pebble Time 2 only, with firmware supporting SDK 4.33 HRV APIs. Pebble 2 Duo and Round 2 do not have the required heart-rate sensor. Only one third-party background worker can run: another background app can replace Sentinel. After a reboot or interruption, check monitoring status and restart it if needed. Frequent recordings use more battery.

SpO2 is not supported in this release. An unavailable placeholder is not an oxygen measurement. Trust symptoms and appropriate medical advice, not a normal app status.

Strava GPX turns your Pebble Time 2 into a standalone GPX workout recorder for cycling, running, and walking. It captures GPS distance, speed/pace, and heart rate, and saves a GPX file directly to your phone's Downloads folder when you stop. No account, no subscription, no cloud dependency — the file is yours immediately.

Import the .gpx into Strava, Komoot, Garmin Connect, or any platform that accepts the format. For users who want automatic delivery, an optional Cloudflare Worker can email the file to you the moment the workout ends.

What it records: elapsed time (pause/resume), GPS distance, speed/pace (km/h or mph / min/km or min/mi), heart rate
embedded at every track point.

Sports: Cycling (speed), Running, Walking (pace), each with independent HR sampling interval.

Settings: HR interval 1–30 s per sport · GPS accuracy filter · metric or imperial · optional download subfolder · optional Worker for email delivery.

Eye Trainer is a guided eye-relaxation and screen-break app for Pebble Time 2.
The approximately seven-minute routine combines Bates-inspired relaxation and shifting concepts with simple modern eye-break exercises such as near/far focus. Visual demonstrations teach each action, while vibration cues and simple reminders let you complete most of the session without watching the screen.
The 12-exercise routine includes palming, gentle blinking, comfortable shifts between details, long swing, central focus, near/far changes, distance viewing, and rest. Physical buttons provide quick pause, resume, previous, and next controls.
Eye Trainer works offline and does not collect or transmit personal data.
The app is intended for relaxation and screen breaks. It does not claim to improve eyesight, cure myopia, correct refractive errors, or treat eye disease. It is Bates-inspired, not the Bates method or an official Bates routine.

Gym Zones is a focused strength-training companion for Pebble Time 2. Start and finish workouts manually, see current BPM and a rolling one-hour graph, track a stable heart-rate zone, and run a configurable between-set rest timer. The app can reopen when rest ends and preserves an active workout for ten minutes after you exit.

Outside a workout, take a one-minute resting PPG-RMSSD measurement and compare it with a personal seven-day baseline. HRV is an optical wellness estimate, not a medical measurement or readiness score.

Gym Zones has no account, server, GPS, or network service and does not transmit workout or sensor data. Settings stay locally on the watch and in Clay on the phone; Pebble Health synchronization, if enabled, is managed by PebbleOS. Assign Gym Zones to Settings → Quick Launch → Tap Up for direct access.

This is a very simple app for people with diabetes to keep track of their short-acting insulin use. 

Use the up/down buttons to adjust the dose in 1-unit steps, then press select to log it with the current time. Long-press select to review your last 3 recorded doses. Designed for quick, low-friction dose tracking without needing your phone.

Allure is an activity tracker for the Pebble Time 2 that turns your heart rate into color. Pick an activity, start, and glance at your wrist: the screen color shows your effort zone, and the current time stays visible.

## Why Allure exists

Allure is directly inspired by the official Pebble Workout app. It reuses its idea of a simple, glanceable workout screen and adds color-coded heart-rate zones.

The goal was not to replace everything, but to improve the official experience while keeping features that make sense on the watch: clear information, large readable numbers, and controls that work naturally during a workout.

Allure is my first app. I originally created it for my own training goals, then improved it thanks to feedback from users. My philosophy is simple: everything shown on the watch should be useful, clearly defined, and easy to understand at a glance.

Allure is an independent community project, not affiliated with or endorsed by Pebble.

## During a workout

- Three activities: walk, run and workout.
- Live heart rate with 5 effort zones, each with its own color, and the time always visible.
- Large numbers, easy to read while moving.
- Walk and run: switch between duration, steps, distance, pace and speed with one button.
- Workout: a simple view with duration and heart rate only.
- Heart rate is recorded continuously during the session.
- When your heart-rate zone changes, Allure records the transition time, the new zone, and the time spent in the previous zone.
- Optional alerts for kilometres or miles, heart-rate-zone changes and workout intervals.

## After a workout

- End of session: rate your effort, from relaxed to exhausting.
- Session summary: effort, average and maximum heart rate, plus estimated calories. The summary color follows your effort.
- Session timeline: an histogram of your effort over time, with achievements and key events such as heart-rate-zone changes.
- Activity journal: save up to seven recent sessions and reopen their detailed summaries.
- Achievements to celebrate your progress.

The timeline helps you see how your effort was distributed during the session. The summary gives the essential results, while the journal keeps your recent sessions available on the watch.

## Settings (on your phone)

- Metric or imperial units (km, mi, kg, lb).
- Sex, age, height and weight: zones and calories adapt to you.
- Optional custom step length for walking and for running, for a more accurate distance.
- Session and weekly goals, in steps or distance.
- Alerts: vibration and/or sound for distance, heart-rate zones and intervals.
- Clock: 12-hour time with optional AM/PM, or 24-hour time with an optional leading-zero option.
- Vibration level.

## Languages

English, French, German, Spanish, Italian and Portuguese, following your watch language.

## Requirements

A Pebble Time 2 with the heart rate sensor enabled.

## Important notice

There is no GPS: distance, pace and speed are estimated from your steps. Heart-rate zones and calories are estimates too, and Allure is not a medical device. Feedback and bug reports are very welcome on GitHub.

CUEKIT — A pocket stage manager for real life.

Give your next activity a rhythm, then let your Pebble guide you through it. CueKit takes a three-step plan and turns it into discreet haptic cues: one pulse for step one, two for step two, and three for step three. You can keep your phone away and focus on what you are doing.

Choose a ready-made flow for a presentation, home reset, movement break, or deep work—or copy one into MY ROUTINE and customize the three stage labels and durations right on the watch.

• One-tap start; pause, skip, or restart individual stages
• A clear countdown and segmented visual progress track
• Haptic patterns that identify the current stage without looking
• Background stage wakeups, with an explicit warning if scheduling fails
• Custom routines saved across app restarts
• Designed for Pebble 2 Duo, Time 2, and Round 2
• Offline, free, zero accounts and no data collection

The source is available under the MIT license. Cues are for everyday routines, not safety-critical use. Background wakeup delivery can vary by firmware and power state.

Track daily steps with a live progress fill, streak counting, bonus goals, and mid-goal encouragements — built for Pebble Time, Time Round, and Pebble Time 2 (Emery).

This app is designed for gym exercises as well as circuit training classes. It's been made so I can easily track my progress during Lifted exercises classes. I then added workouts to be able to do the same in a regular gym.

Exercises can be created on the watch or in the settings page. Weights used for exercises can be tracked easily, for example during Lifted's circuit training class. There is also a workout mode which allows you to create your own set of exercises. Workouts will use vibrations to let you know when a set starts, how to pace your repetitions and when to take a break after each set.

The app works even if bluetooth has been lost, because you might not want to take your phone to the gym or to class. Changes made on the watch will sync to the phone when it's reconnected.

See your rest timer and current set on your wrist. Finish a set in the GymLog Android app and the watch shows the exercise, your target weight and reps, and which set you're on, with a live rest countdown. Log the set as Easy or Hard, extend the rest, or feel a buzz when the rest ends, all from the watch. It works offline over Bluetooth through the Pebble app, with no internet or account needed. Requires the GymLog Android app.
