Hundrd turns living long and strong into something you do a little of every day.

Pick a challenge, check in each day, and watch your streak grow. Small, repeatable habits — done consistently — are what actually change how you feel, and Hundrd is built around that one idea.

What you can work on
• Movement — move more, sit less, build strength
• Nutrition — eat better without a rigid diet
• Sleep — wind down and rest properly
• Mind — breathe, focus, and quiet the noise
• Connection — stay close to the people who matter
• Learning — keep your mind sharp
• Digital wellbeing — spend less time on the screen

How it works
• Take on a challenge from a curated library, or create your own
• Check in every day — your ticks save even when you're offline
• Keep your streak and see your consistency build over time
• Get a nudge when you slip, and a cheer when you show up

Plan your day
A built-in to-do list turns your intentions into a short, doable plan, right next to the habits you're building.
