Watch
It notices before you do.
Transfer bonuses open and close. Award charts change. Credits reset. TripStacker reads all of it against the cards you actually hold.

Your points already have somewhere to be.

Plan
One trip, worked backward.
Name a place you want to go. TripStacker works back from the seat to the points, then tells you which of your balances can actually get there.
Prove
Every find gets written down.
Each thing it surfaces goes into your ledger with the math underneath it. At the end of the year you can see exactly what it was worth.
The audit
The credits your cards already carry.
Ten popular travel cards, with the statement credits TripStacker tracks on each one. Tap the ones in your wallet.
Typical annual values, taken from the same card records the app tracks against. Treat them as estimates.
How TripStacker works
A quieter way to use the points you already have.
No dashboard to check, no spreadsheet to keep up. You set it up once, then it speaks when something in your wallet is worth acting on.
Step 01
You add your cards
No bank logins, ever
You type in what you hold and roughly what your balances are. TripStacker never asks for a bank password and never sees a card number.
Step 02
You name one trip
A place, not a plan
Tell it somewhere you actually want to go. That single answer is what turns a pile of points into a target.
Step 03
It watches the gap
Quietly, in the background
Transfer bonuses, award price changes, credits about to reset, annual fees coming due. It checks against your wallet so you do not have to.
Step 04
It tells you the one thing
One screen a day
Most days there is nothing to do and it says so. When there is a move worth making, that is the whole screen.
The app
Built to be glanced at.
One screen a day tells you what moved and what to do about it. Everything else stays quiet until it matters.

Questions
Straight answers.
Bank access, award availability, the guarantee, and what happens to your data when you leave.
Do you connect to my bank accounts?
No. You type in the cards you hold and roughly what your balances are. Nothing is linked, so there is no login to hand over and no card number for us to lose. It takes a few minutes once, and it means the app can never touch your money.
Do you show live award availability?
No, and we will not pretend to. TripStacker works from published award charts, historical award price data, and the transfer and benefit rules of the programs you hold. It tells you what a trip should cost and whether your points can reach it. You confirm the seat with the airline.
What if I already know what I am doing?
Then you already know the hard part is not the strategy, it is the remembering. Transfer windows open on a Tuesday and close before you notice. Credits reset. Fees post. The value here is the watching, not the teaching. You stay the one deciding.
How does the guarantee actually work?
It runs on your ROI ledger. Everything TripStacker surfaces is written down with the math under it, priced at conservative published values. Two conditions: your wallet is set up, and you were active in 6 of your 12 months. Annual plans only. Short at month twelve, we refund the year.
What happens to my data if I stop paying, or delete my account?
Cancel and your ledger stays, frozen and visible. At the end of the paid period the account drops to Carry-On and keeps working. Delete your account and your data goes with it. What we hold and for how long is written out in the privacy policy.
Is this affiliated with any airline, hotel, or bank?
No. TripStacker is built by Cosmo Solutions LLC, a one-person company. No airline, hotel group, or card issuer pays us, reviews our numbers, or has any say in what the app tells you. Program names appear only to describe your own points.
Is Roux a human?
No. Roux is an AI advisor built on Claude. It reads only the wallet you enter, and it tells you when it isn't sure.
Why is there no monthly plan?
Because the promise takes a year to keep. The 10× guarantee is measured across twelve months of your ledger, so a monthly plan cannot carry it. Billing is yearly. The first thirty days are unconditional: if it is not for you, we refund everything.
Is there a free plan?
Yes. Carry-On is free: three cards, one trip goal, your daily Today screen, and an ROI ledger counting from day one. Roux is capped at 25 messages your first month, then 10 a month. The guarantee is not attached, because there is nothing to refund.
