Highlights
- Living Values system with Tamagotchi-style decay
- Casino psychology: 30% random bonus rewards
- Social leaderboards and group challenges
- Apple Watch companion with complications
The Challenge
Traditional productivity apps feel like chores. Users abandon them within weeks because completing tasks offers no emotional payoff. The challenge: make personal growth genuinely addictive without being manipulative.
- Static values have no emotional weight - easy to ignore
- Fixed rewards are predictable and lose motivational power
- No sense of progress beyond simple checklists
- Task completion feels mechanical, not rewarding
