Habit forming app

Fabulous leans on commitment psychology during onboarding. Our UX Bites cover tactics including a contract in your own name, signed with a mimicked thumb impression.

Key takeaways from 1 UX Bite

  • Onboarding shows a contract in your name, written in first person, so commitment feels self-made

  • You sign by mimicking a thumb impression, making the promise feel physical and binding

  • Commitment is front-loaded before habit-building, giving users something to hold themselves to
