Small transfers. Big goals.
How it works
Everything works together to protect you.
Six systems, one job: turn everyday spending into intentional progress — safely.
Every purchase rounds up by a smart, mode-aware amount — gentle on rent and big bills, never reckless.
Before any stack we check balance, pending charges, upcoming bills and your buffer. If it's not safe, we skip.
Goals for emergencies, debt, a home, travel, or your business — each one filling on its own.
One roundup, spread across every active goal by the exact percentages you set.
Honest, no-shame guidance grounded in your real numbers — finds money you can safely save.
Two-minute lessons that turn small habits into lasting confidence.
The Safety Engine
We never put your balance at risk.
Every potential stack runs through a live check against your real money. If the math says it isn't safe, Stack reduces, delays, or skips it — automatically. Four possible decisions, your balance protected every time.
Always in control
Four modes. You set the pace.
