Get your number →Most money apps drown you in features. We built one that answers a single question.
Every month, One Number families are reporting:
No onboarding gauntlet. No 47 categories to set up. Open the app and you're done in under two minutes.
Your paycheck, side income, anything you know is landing this month. Quick and only once.
Rent, bills, the recurring stuff. We do the math. You do nothing.
The amount you can spend without breaking anything. Updated as life happens.
Not a big tech company. Not a 50-person product team. Just us, our kids, and a chalkboard on the kitchen wall.
For years we struggled to stay on top of money. Not because we didn't care — because every app turned a simple question into a part-time job.
So one weekend we wrote our own system in chalk on the wall: what's coming in, what's going out, what's left for the month. For the first time, we felt in control.
One Number is that chalkboard, in your pocket. Nothing more, nothing less.
