What People Say

Specific outcomes. Real people.

I had no idea my design side hustle was only making me $6/hour after time. Stack showed me in 30 seconds. Dropped it and moved my freedom year from 2048 to 2043.

Every finance app I tried couldn't handle the month my consulting paid $8,000 and my salary paid $0. Stack just handles it. My freedom year is 2037 and watching it move is addictive.

I thought I would never retire. Now I can see exactly when I will. 2046 felt hopeless. Stack showed me 2041 is achievable with one change.

FAQ

Common questions

What exactly is a Freedom Year?
+
Your Freedom Year is the specific year your investment portfolio generates enough passive income to cover all your living expenses. Stack calculates it using the Rule of 25: your FI number = annual expenses × 25. When your savings hit that number — growing at a real 7% annual return — you're free.
Do I need to link my bank?
+
No. Stack is manual-logging only. Type in your income and expenses — it takes 60 seconds. No Plaid, no bank credentials, no data leaving your device. Everything stays local.
Is it free?
+
Yes, the core app is free forever. A Stack Pro tier will unlock bank linking, advanced charts, and tax estimates when we launch. The Freedom Year calculator and all core tracking features will always be free.
When does Stack launch?
+
We're in final testing now. Join the waitlist and you'll be among the first to get access — well before the public launch.

The Honest Truth

AI is changing what a career looks like.
Build your exit plan before one is built for you.

The people who come out ahead already knew their number, tracked every income stream, and had a plan. Stack gives you that plan — updated every single day.
