Saving works better when it’s simple.
Stack is a savings app where you set goals, track progress, and stay consistent.
Start from zero, keep momentum, and build a routine that lasts.
App preview
Start with one goal and track each pay-in toward your target.

Built around simple, repeatable saving
Three focused tools that work together to make saving feel light, social, and doable — every single week.
Stacks
Create focused savings goals and track progress in one place.
Clear progress
Simple progress tracking keeps your savings routine on track.
Redirect spending
Turn skipped purchases into shared progress instantly.
From zero to your first deposit in under a minute
Three simple moves. Stack keeps saving practical and easy to maintain.
Create your first stack
Pick a clear target and define what success looks like.
Set a goal
Pick something concrete — a trip, a buffer, a shared “no-spend” month.
Track each pay-in
Log progress consistently and watch your goal move forward.
Built for real life
Same product, different stories — pick the one that sounds like your crew.
Trip fund
Pool momentum for flights and hotels without awkward spreadsheets.
Emergency buffer
Build a safety net with a steady plan and visible progress.
No-spend month
Commit to a focused month with clear boundaries and milestones.
Your money is safe with Stripe
Every deposit and transfer on Stack is processed by Stripe — the same trusted payments infrastructure used by Apple, Amazon, and millions of businesses worldwide.
Bank-level security, end to end
We never see or store your card or banking details. Stripe handles every transaction with the highest security standards in the industry.
Money is a daily behavior
Most people don’t fail because they don’t know what to do. They fall off because habits are hard to keep.
Stack makes saving clear and repeatable — so you actually stick to it.
Private doesn’t mean complicated
Stack is designed to keep your progress personal and clear. We only collect the minimum needed for waitlist and app access, and we never sell personal data.
Private by default
Your goals and activity stay in your account unless you choose to share.
You control sharing
You choose if and what to share, including progress, milestones, or notes.
Policies
Full privacy policy and terms will ship before public accounts. Until then, we only collect what the waitlist needs.
