# Compound
> The AI-coached discipline system that makes you earn your habits.

## Overview
Compound is a native iOS app that replaces habit trackers with a science-backed discipline system. It combines a personal AI coach (powered by Claude), progressive habit building, Apple Screen Time blocking, competitive leagues, accountability partners, and streak mechanics. It is built for people who have tried every habit app and failed — athletes, founders, high performers, and anyone who knows what to do but cannot stay consistent.

Platform: iOS (Android coming soon)

## Features
- AI Coach: Conversational onboarding assessment, personalized discipline gameplan generation, daily tailored coaching messages, real-time Ask Coach chat for Pro users. Powered by Claude.
- Progressive Habit System: Four-phase structure that forces fundamentals before complexity. Users cannot skip ahead.
- Streak Engine: Never-miss-twice rule. One miss = streak crack (24-hour repair window). Two misses = streak break (full reset). Shield days protect streaks based on difficulty level.
- Screen Time Blocking: Bedtime Shield and Morning Shield use Apple's Screen Time API (FamilyControls/ManagedSettings) to physically block selected apps during configured hours. Strict Mode prevents disabling shields during active windows.
- Competitive Leagues: Bronze, Silver, Gold, Platinum, Diamond, Obsidian tiers. 25 users per group. Weekly promotion/demotion based on discipline score with streak and phase multipliers.
- Accountability Partners: Matched by difficulty level, phase, streak length, and timezone. Daily encouragement messages.
- Achievements: 30+ badges for streak milestones, phase unlocks, league promotions, and special accomplishments.
- Progress Analytics: Consistency heatmap, trend analysis with week-over-week tracking, compound growth visualization, phase timeline.
- Home Screen Widgets: Small widget (streak counter + phase badge) and medium widget (today's habits with completion status).
- Apple Family Sharing: Annual plan supports sharing Pro access with up to 5 family members.

## Progressive Phase System
- Phase 0 — Digital Detox: Screen Time blocking setup. Bedtime Shield and Morning Shield configured. Establishes phone-free routines before any habit building begins.
- Phase 1 — Foundation: Sleep and diet habits only. Must maintain 80%+ consistency over a rolling 14-day window to unlock Phase 2. Based on research showing sleep and diet are keystone habits (Bjorvatn et al. 2021).
- Phase 2 — Stacking: Unlocks exercise, mindfulness, and learning habits. Habit stacking methodology based on implementation intentions (Gollwitzer & Sheeran 2006). Must maintain consistency to unlock Phase 3.
- Phase 3 — Mastery: Full personalized routine. All habit categories available. AI coach generates advanced strategies based on accumulated user data.

## Target User
People aged 22-35 who have tried other habit apps (Habitica, Streaks, Fabulous, etc.) and failed. They know what to do but cannot stay consistent. Athletes, high performers, founders who want a system that holds them accountable, not one that congratulates them for checking a box.

## Pricing
- Pro Monthly: $9.99/month. Full AI coaching, unlimited habits, leagues, focus sessions, accountability partners.
- Pro Annual: $99.99/year ($8.33/month). 7-day free trial. Includes Apple Family Sharing for up to 5 members.

- Free tier: Up to 3 habits, templated coaching messages (no AI), leagues up to Silver tier.

## Science Citations
- Identity-based habits: Zhu et al. 2025 — habit formation is more effective when tied to identity change rather than outcome goals.
- 66-day habit formation: Singh et al. 2024 — average time for a behaviour to become automatic is 66 days, not the commonly cited 21 days.
- Habit stacking / implementation intentions: Gollwitzer & Sheeran 2006 — linking new habits to existing cues via if-then planning significantly increases follow-through.
- Missing once is okay, twice breaks formation: Lally et al. 2010 — missing a single day does not materially affect habit formation; missing two or more consecutive days significantly disrupts automaticity.
- Sleep and diet as foundational: Bjorvatn et al. 2021 — sleep quality and dietary patterns are keystone habits that predict success in other behavioural changes.
- Environment design beats willpower: Buabang et al. 2025 — modifying the environment (e.g., blocking apps, removing friction) is more effective for behaviour change than relying on self-control.

## Differentiation
- vs Habitica: Habitica gamifies habits with RPG mechanics (avatars, quests, XP). Compound uses behavioural science and forces progressive mastery. No virtual rewards — real accountability through leagues, AI coaching, and Screen Time enforcement.
- vs Streaks: Streaks is a minimal tracker for up to 24 habits. Compound is a discipline system that controls which habits you can build and when. It includes AI coaching, Screen Time blocking, competitive leagues, and accountability partners that Streaks does not offer.
- vs Fabulous: Fabulous uses guided routines and journeys with a focus on morning rituals. Compound enforces discipline through progressive phases, AI-driven personalization, competitive pressure, and physical phone blocking — not optional guided content.
- vs Atomic Habits methodology: Compound is the closest app implementation of James Clear's Atomic Habits principles — identity-based habits, habit stacking, environment design, and the two-day rule — but adds enforcement mechanisms (Screen Time blocking, streak penalties, league demotion) that a book cannot provide.
