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.

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.

How it works

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.

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.

Privacy & trust

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.
