App Specification & Programming Guide

10 for Life

Build 10 habits. Track 10-day streaks. Become your best self.

1. Project Overview

10 for Life is a habit tracking mobile application designed as a companion to the 10 to Win task management app. While 10 to Win handles one-off and project-based tasks, 10 for Life focuses on building consistent daily habits and routines.

Key Differentiator

Tasks vs Habits: Tasks are things you complete and check off. Habits are recurring behaviors you build over time. 10 to Win handles tasks; 10 for Life handles habits. Together, they form a complete productivity ecosystem.

2. Core Philosophy & The "10" Theme

The number 10 is central to the app's identity and functionality, creating brand consistency with 10 to Win while providing meaningful constraints and milestones.

10 Habits Maximum

Research shows people can realistically maintain 5-10 habits. The app enforces a limit: "Choose your 10 most important habits. No more, no less." This forces prioritization and prevents overwhelm.

10-Day Streak Milestones

Instead of daunting 21-day or 66-day goals, celebrate every 10-day milestone. Day 10 = Bronze, Day 20 = Silver, Day 30 = Gold. Makes progress feel achievable.

10-Minute Default Sessions

For time-based habits (meditation, reading, exercise), default to 10-minute sessions. Same philosophy as 10 to Win: "Anyone can do anything for 10 minutes."

Daily Score Out of 10

Complete all tracked habits to achieve a "Perfect 10" day. Gamification with daily scoring that's simple to understand and motivating to achieve.

10 AM / 10 PM Check-ins

Optional morning review (what habits today?) and evening reflection (what did you complete?). The times reinforce the brand identity.

10-Week Mastery Program

A structured 10-week journey to cement one new habit, with weekly coaching prompts and milestone celebrations.

Design Principles

  1. Constraint breeds focus: Limiting to 10 habits prevents the "track everything" trap
  2. Achievable milestones: 10 days is long enough to feel meaningful, short enough to feel reachable
  3. Consistency over perfection: One skip day per 10-day period doesn't break streaks
  4. Celebration matters: Visual rewards for every milestone achieved
  5. Simplicity first: Easy to log, easy to understand, easy to build momentum

3. Companion App Relationship

10 for Life is designed as a sibling app to 10 to Win, not a competitor. They serve different but complementary purposes.

Aspect 10 to Win Tasks 10 for Life Habits
Purpose Get things done Build yourself
Item Type Tasks (complete once) Habits (repeat daily)
Success Metric Tasks completed Streaks maintained
Time Horizon Today / This week Ongoing / Lifetime
Mental Model "What should I do?" "Who do I want to become?"
Primary Color Orange (urgency) Green (growth)
Tagline "Win your day in 10 minutes" "10 habits. 10-day streaks. For life."

User Journey Example

Morning: Open 10 for Life, complete morning habits (meditate, drink water, exercise).

Workday: Open 10 to Win, tackle your Top 10 priority tasks in 10-minute focused sessions.

Evening: Return to 10 for Life, complete evening habits (journal, no screens, in bed by 10:30).

4. Visual Identity

The app should feel like a sibling to 10 to Win - same design language, different color palette.

Icon Motifs

App Icon Concept

The app icon should feature a stylized flame or growing plant in green/teal gradient, with subtle "10" integration (could be 10 leaves, or the flame shape suggesting "10"). Simple, memorable, pairs visually with 10 to Win icon.

9. Integration with 10 to Win

The two apps can work together to provide a comprehensive productivity ecosystem.

Shared Notification Strategy

When both apps are installed, they should coordinate notifications to avoid overwhelming the user:

  • Morning: 10 for Life habits first, then 10 to Win task preview
  • Midday: Only task reminders from 10 to Win
  • Evening: 10 to Win task summary, then 10 for Life evening habits

Energy Sync (Pro Feature)

Habit completion can inform 10 to Win's Flow Sync mode:

10 for Life Habit Effect on 10 to Win
Exercise completed Boost "High Energy" factor for next 2 hours
Good sleep logged Morning tasks get energy boost
Meditation completed Boost focus for complex tasks
Missed exercise Suggest lower-energy tasks

Cross-App Links

Unified Daily Score (Future)

Combined "10 Score" Concept

A daily productivity score combining both apps:

  • Habits Score (0-5): Based on % of habits completed
  • Tasks Score (0-5): Based on priority tasks completed
  • Combined Score (0-10): Your daily productivity rating

URL Scheme

// 10 for Life URL scheme tenforlife:// // Open app tenforlife://today // Open Today screen tenforlife://habits // Open Habits list tenforlife://habit/{id} // Open specific habit tenforlife://timer/{habitId} // Start timer for habit // 10 to Win can call tenforlife://complete/{habitId} // Mark habit complete tenforlife://energy-sync // Request energy data
