Build habits with momentum.
Show up each day to build velocity. Miss a day and you only coast - never crash. Every habit is a rocket aimed at the Moon, then Mars, then the whole solar system.
Free forever. Private by default - no feeds, no followers, no ads.
Show up
Check in once a day. Day one already counts - you leave the launchpad the moment you start.
Build velocity
Each refuel adds thrust. Consistency compounds, so your rocket climbs faster the longer you keep going.
Reach milestones
Pass through orbit, the halfway point and touchdown on the Moon - then push on toward the planets.
One missed day won't undo you
Most trackers punish a single slip by resetting you to zero. Momentum uses gentle gravity instead: miss a day and you coast, abandon it for weeks and you slowly fall back. Your trajectory shows exactly where you're headed if you keep going - and what you'd give up if you stop.
Aim for somewhere worth reaching
A hundred days of momentum lands you on the Moon. Keep flying and Mars, Jupiter and the outer planets come into range. Every habit always knows where it set off from, where it's headed next, and how close you are.
Every milestone gets its moment
Break through the atmosphere, reach orbit, hit the halfway mark, touch down on the Moon - each milestone arrives with a little fanfare, so the long arc stays rewarding from day one.
Track a number, not just a tap
Some habits live and die by a number - minutes meditated, kilometres run, pages read. Set a daily or weekly target and log the value when you check in. A separate chart plots every entry against your goal, with on-target weeks in green and shortfalls in red - so progress and slips are equally clear.
Some habits don't need every day
Pick exactly when each habit is due - every day, only Tue/Thu/Sat, or just once a week on whichever day suits you. Weekly habits stay scheduled but unobtrusive: a quiet moon on off days, a celebratory badge the moment the week is fulfilled.
Built to be yours, and yours alone
Private by default
No public profiles, no social feed. Your habits are for you.
Your habits, your data
Import a CSV from another tracker, or export your own any time. Values, weekly targets and schedules round-trip cleanly - nothing's locked in.
Flexible cadence
Daily, specific weekdays, or once a week. Pick what fits the habit - no daily guilt for a weekly thing.
Charts that mean it
A trajectory chart for momentum, a weekly-totals chart for values - on-target weeks green, shortfalls red.
Free, no catch
Every feature, no paywalls, no ads. momentum is completely free.
Mobile-first
Designed for a quick daily tap, fast and comfortable on your phone.
Your first day of momentum is one tap away
Pick a habit, light the engines, and watch it climb. Always free - the Moon is one hundred days away.
