Hevy Workout Routine Companion & History Tracker for Pebble Smartwatches

NOTE

This is a Vibe-Coding project! 🎸✨ Built interactively using advanced agentic AI pair-programming to prototype, test, and implement features on-the-fly.

PebbleGym brings your fitness routines directly to your wrist. Compatible with all Pebble platforms (optimized for Pebble Time 2/emery), it allows you to import your training plans from the provider Hevy using public links. During the workout, the watch displays the current set with target values, compares them with your history ("Last Time"), and logs your achieved weights and repetitions. Thanks to a clever protection mechanism (long-press), accidental clicks are prevented, and a quick exercise menu lets you flexibly jump between exercises at any time if a machine in the gym is occupied.

Hourly Steps mimics Fitbit's "Reminder to Move" functionality but with way more user control.

Through App settings you can adjust:

- What hour to start getting reminders
- How many minutes before the end of the hour to get reminded to move
- How many hours you want to be reminded to move
- The minimum steps you want to be reminded to do each hour
- What your daily step goal is
- What days of the week you want to receive reminders
- All the colors used in the app's visual appearance

Hourly Steps will even help you reach your daily step goals by splitting that goal by your active hours and showing it as a stretch goal after hitting the minimum.  For example: if you want to do 10,000 steps a day and be active for 10 hours a day, it'll show a stretch goal of 1,000 steps each hour after finishing the minimum steps.  That stretch goal will automatically adjust if you get closer to that goal or fall behind, creating a "deficit" or "surplus" value that shows how on track you are.  You'll even get a Fireworks show upon completion of daily steps.

Please allow an hour after installing for the app to establish steps at the start of the next hour.  It may show an incorrect hourly steps value until then.

Note: Due to Pebble limitations around tracking steps within a specific time frame, this app uses a background worker to get steps at the start of each hour and determine when to open the app for reminders.  You can optionally turn this off if you need the background worker for something else.  This will cause Hourly Steps to use wakeup timers instead, however that has some limitations.  Since there can only be one Foreground app at a time, it'll close down any other app you have open even if it doesn't need to remind you of steps.  This will happen once at the start of an hour and once during active hours at the reminder minute you set (but not outside of active hours).  It may also fail to use the timers entirely if another app has scheduled a wakeup for the same minute  This should not happen with background worker active.  Because of this I highly recommend keeping the background worker active.

# 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)
