Cosmo - Don't Break The Chain
Build Streaks, Crush Habits
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Meet Cosmo, your personal astronaut guide. Build unbreakable habits one link at a time - skip a day and the whole chain shatters. Are you disciplined enough?
YOUR CHAIN IS ONLY AS STRONG AS TODAY.
Cosmo is a habit tracker built on one powerful rule: show up every day, or start over. No excuses, no catch-up days. Just you, your astronaut guide Cosmo, and the chain you're building together.

HOW IT WORKS
* Pick a habit. Choose your challenge - 3 days, 1 week, 1 month, or 1 full year. Every day you complete your habit, a new link is forged in your chain. Miss a single day? The entire chain breaks and you restart from day one.
* This isn't about being perfect. It's about learning what consistency really feels like.
---
MEET COSMO
* Cosmo is the astronaut who walks beside you on every chain. His torch lights up only your next link - keeping you focused on today, not overwhelmed by tomorrow. Customize Cosmo with 11 unique looks, from Pirate to Chief to Rapper.
---
WHY IT WORKS
* Most habit apps let you skip days and catch up later. Cosmo doesn't. The "don't break the chain" method is backed by behavioral psychology - visible streaks create a powerful urge to keep going. When you can see your chain growing link by link, skipping a day feels like watching it shatter.
