Cloudbreak — A little air. A little less chaos.

Your wrist has enough reminders to do things. Here’s one to take a breath.

Meet Cloudbreak: guided breathing with a happy little cloud and a whole lot of Pebble personality. Bold outlines, crisp colors, playful expressions and snappy slide-and-bounce transitions make taking a breather feel right at home on your watch.

Between meetings, before bed, or after opening your inbox against your better judgment, make a little room in your day to pause. Pick a rhythm, choose your time, and let your cloud handle the counting.

SMALL CLOUD. PLENTY OF FEATURES.

• Four breathing rhythms: Balanced, Long Exhale, Box and 4-7-8.
• Suggested session lengths, plus custom durations from 1 to 15 minutes.
• An animated cloud that grows, floats, holds and puffs along with your breath.
• Distinct vibration cues for inhale, hold and exhale, plus a session-complete celebration.
• A starting heart-rate check, live heart rate and time remaining.
• Session summaries with starting, ending and average heart rate, percentage change, duration and completed cycles.
• A post-session mood check-in with a cloud face to match.
• Saved daily streaks, personal bests and session totals.
• 36 rotating daily tips selected around your usage and time of day.

No leaderboard for breathing. No cloud judging your lung capacity. Just a small daily pause, with a very good face.

Cloudbreak. Give your day some breathing room.

Designed for Pebble Time 2. A valid heart-rate reading is required to start a session. Heart-rate changes are descriptive, not a relaxation score or medical assessment. Breathe comfortably; pause if a rhythm doesn’t feel right.

# Tiny RPG Day

*Your inner world, as an RPG character.*

A self-awareness companion for Pebble smartwatches that transforms your current mental and emotional state into an RPG-style character—complete with class, narrative, and suggested quests.

## ✨ What Is It?

Tiny RPG Day isn't a game—it's a **tiny mirror**. Through quick check-ins throughout the day, it reflects your energy, mood, social battery, focus, and overwhelm as a playful character profile. Are you a **Fog-Walker** trudging through mental haze? An **Ember Knight** blazing with focus? A **Cozy Druid** in perfect balance?

Each check-in becomes a chapter in your daily story, tracking how your inner state evolves from dawn to dusk.

**Core Philosophy:** Supportive, not competitive. Clever, not childish. A companion, not a judge.

## 🎮 Features

- **Quick 5-step check-ins** — Rate your Energy, Mood, Social Battery, Focus, and Overwhelm
- **14 unique RPG classes** — Dynamically assigned based on your state
- **Narrative storytelling** — Each check-in is a "chapter" with time-of-day themes (Dawn, Journey, Return, Rest)
- **Transition tracking** — See how your state changed since your last check-in
- **60-day history** — Your story persists, viewable as a scrollable journal
- **Time-aware visuals** — Background colors shift with the time of day
- **Visual stat bars** — See your values as `[####--]` progress bars
- **Progress indicators** — Track your check-in flow with `[**---]`
- **Color support** — Beautiful colors on Basalt/Chalk/Emery, graceful B&W fallback on Aplite/Diorite

Track your caffeine like your body actually processes it.

HalfLife is a real-time caffeine tracker for Pebble that simulates how caffeine is absorbed, peaks, and wears off — so you can stay energized, avoid crashes, and sleep better.

    Note: This is a mathematical model, not medical advice.

> Why It’s Different

Most apps just estimate. HalfLife simulates using a pharmacokinetic model, it tracks your caffeine levels continuously — so you always know where you stand, not just what you drank.

> What You Get
  - Real-time caffeine levels: updates every second — no static estimates.
  - Peak prediction: see when your caffeine will hit hardest — and how strong it’ll be.
  - Smart sleep guidance: know when your levels are low enough for quality sleep.
  - 6 Custom drink presets: save your go-to coffee, tea, or energy drinks.
  - Flexible drinking durations: 3 presets of 5 to 120 minutes
  - Preferred caffeine range: Stay in your ideal focus zone at a glance.
  - Free-form logging: enter any caffeine amount anytime.

> Built Around You

Everyone processes caffeine differently. HalfLife lets you adjust:

  - Caffeine half-life (how fast it leaves your body)
  - Absorption speed (how fast it gets absorbed into your bloodstream)
  - Your personal sleep threshold
  - Your preferred caffeine range (color display watches only)
  - Or just use the built-in defaults and go.

> Real-World Uses
  - Time your morning coffee for peak focus
  - Avoid the afternoon crash
  - Don’t ruin your sleep with late caffeine
  - Plan pre-workout energy boosts
  - Understand how multiple drinks stack over time

> Private & Efficient
  - 100% on-device – your data never leaves your watch
  - No background drain – zero battery impact when closed
  - Open source – transparent and customizable

> Coming Soon
The core model is solid, but I still have some exciting plans for the future:

  - Redesigned UI: A visual "glow-up" is the top priority, including support for round Pebble watches. (Already making minor progress, but I'm a bioinformatician, not a designer — so bear with me.).

  - Edit active drinks: In case you set the wrong amount or duration, this feature will allow you to edit and delete your current drinks.

  - Shake For Help: Shake the watch on any screen of the app for a guide on the controls and meaning of values. (With an option to disable this if you already know what's what).

  - On-watch configuration: Configure most settings without needing to grab your phone.

  - “Preview before you drink” feature: See how a drink will affect your levels before you log it.

  - Drink planning: Plan you day's caffeine for workouts, productivity or to regulate your levels in advance. Get notifications for the drinks you scheduled when viewing the caffeine graph across 12-72 hours.

  - Closed-Loop Model: When the new Pebble hardware arrives, the plan is to use advanced heart rate (specifically HRV) data to create a self-tuning model that adapts to your body's unique response. This allows for a broad array of additional features.

Note: Values in screenshots have been tampered with to show off the features. 

Have a feature idea or found a bug? The code is open and contributions are always welcome! (Also some extra details on the model coming soon for the science nerds)

Volleyball Scorer turns your Pebble into a glanceable, sunlight-readable scoreboard. Hold the top button to add a point for US and the bottom button for THEM, and the watch buzzes the moment a set is won at 25 by two. Tapped the wrong team? Press the middle button to arm removal, then press a team to take a point back. Your score saves automatically, so you can close the app mid-match and reopen exactly where you left off, with each team's button sitting right next to its score.

DontPanic measures your Heart Rate Variability (HRV) right on your wrist to help you monitor your physical stress and autonomic nervous system balance.

The app evaluates RMSSD (Root Mean Square of Successive Differences) - the gold standard time-domain metric for measuring parasympathetic activity and physical recovery.

How to Measure:
1. Tighten your Pebble watchband comfortably above your wrist bone.
2. Lay down, relax, and keep your hand calm and still for 2 minutes.
3. A synchronized breathing visual and countdown guide you through the session.
4. You will feel a gentle vibration when the measurement is complete.

Features:

Dynamic Stress Gauge: Visualizes your stress percentage and status (CALM, NORMAL, or STRESS) across an analog arc gauge.

Direct RMSSD Value: Accurate millisecond readout of your HRV.

Personalized Calibration: Calibrates to your individual physiology over the first 7 days, continuously refining your baseline over time.

History Trend Graph: Flip through with Up/Down buttons to track your latest 16 measurements and observe long-term trends.

On-Wrist Guide: Press the middle (Select) button anytime to view tips for the most accurate readings.

Screen & Backlight Control: Keeps the display legible throughout the measurement without turning off.

Tip: For consistent results, take your measurement every day around the same time and in the same position (e.g., right after waking up).

Want to track how your body recovers overnight based on HRV? Connect with Sleep as Android!

Focus on the match, not the math. The simplest way to keep track of your tennis score right from your wrist.

Silent Sit: A silent, tactile meditation timer

Silent Sit paces your sitting with vibrations alone. No bells, no sound, no screen to look at: you feel the rhythm on your wrist and keep your eyes closed.

Made for people who meditate and want a timer that is discreet, always there, and speaks only through touch. A phone distracts and tempts you to look at the screen. Your wrist does not.

HOW IT WORKS

- Open-ended sittings: the duration you pick is not an end but a cycle that repeats for as long as you sit, without breaking the rhythm.
- The home screen leads with Start, showing your last-used settings just beneath it: one tap and you begin again like yesterday. Press Down to adjust the duration or tick interval.
- During the sitting the screen shows only the elapsed minutes, large and centred on a dark background. No countdown, no progress bar, no cycle counter to stare at.

THE VIBRATIONS

- Periodic tick (every 10 or 30 min): a brief, light tap.
- Mid-cycle: a medium double.
- End of cycle: two long pulses, then the cycle restarts on its own.

The three patterns are deliberately distinct in rhythm, so you know where you are without opening your eyes.

BUILT FOR MEDITATION

- Detects Quiet Time: if it is off, the app reminds you to turn it on before you begin, so outside notifications do not disturb you.
- Timekeeping anchored to absolute time: zero drift even on long sittings.
- Dark screen and backlight off, to avoid distraction and save battery.

No accounts, no statistics, no cloud. Just you, the breath, and a beat on your wrist.

GymClock — your interval & HIIT timer on the wrist.

Build a circuit from your own named exercises, set the work time, rest time and number of rounds, then start training without ever touching your phone. GymClock counts every interval down for you and uses the watch's vibration to keep your eyes off the screen — so you can focus on the workout.

Features
- Background run & resume
- Independent on the phone
- Custom routines: name each exercise and set work, rest and round count
- Large, glanceable display — current exercise, big countdown, round progress (e.g. "2/5 Lap 3") and a preview of what's next
- Color-coded phases: work and rest are instantly distinguishable (high-contrast on black-and-white watches too)
- Vibration cues: a buzz on the final seconds, the half-way mark, and the end of every interval — plus a long buzz when the workout is done
- Set rest to 0 for non-stop circuits
- Live heart rate (BPM) on watches with a heart-rate sensor
- Skip forward, skip back, pause and reset, all from the buttons
- Settings stay on the watch — once configured, it works fully offline
