## What is Delta?

Track any habit you're building or breaking. Delta pairs short daily check-inswith a growing plant companion, streaks, and rewards — so tracking your habit doesn't feel like a chore.

Delta currently supports tracking nicotine, alcohol, and cannabis use, with more habit categories on the way.

WHY DELTA
 
Most tracking apps ask a lot and give little back. Delta is built around  brief, randomized daily check-ins (2–4 a day, your choice) that take under a  minute — short enough that you actually keep up with them.

Every check-in feeds a companion that grows through six stages as you log consistently. It's not decoration — it's a direct reflection of your own consistency.

FEATURES

  • Personalized onboarding — set your habit, your reason for change, your triggers, and your motivations up front
  • Quick daily check-ins — desire, stress, mood, and context, in under a minute
  • Quick Log — capture a craving or a slip in about 10 seconds, any time
  • Craving SOS — a guided breathing exercise and a 3-minute timer for the
  moments that matter most
  • A growing companion — six evolution stages, driven entirely by your own consistency
  • Streak Shields — a missed day doesn't have to break your streak
  • Real analytics — trends, triggers, and a plain-English breakdown of your patterns
  • Export anytime — download everything as CSV or JSON whenever you want it
