About this app

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 Your coach An accountability coach that actually pays attention. It encourages you on the good days, gently calls out the misses, and answers questions in plain language — there to keep you going, not to lecture.
