Where should your next dollar go?
Everyone with real money has someone watching it. Tapedeck is that person, as software — it puts every spare dollar in order across debt, savings and retirement, then tells you when something needs doing.
The plan it builds
One person's $1,400 a month, in order.
Press play. Watch what happens to the money when a line finishes.
Month
Aug 2026Every figure above is interest arithmetic on the balances, rates and minimums this person entered — the same cascade the app runs, which is why the dates come out to the month rather than to a range. No market return is assumed anywhere in it. These are their numbers, not yours; yours would produce a different order.
Both sides of the tape
Getting out of debt and getting invested are the same problem.
Everybody sells you one half. Budgeting apps stop at the debt. Robo-advisors start at the portfolio and assume you arrived debt-free with a full emergency fund.

Your money doesn't work in halves, so neither does Tapedeck.
Side A — Get straight
Before the market is even the right question
A card at 24.99% is a guaranteed 24.99% return you can collect today, and nothing in the market beats certain. So the card goes first, and the app shows you the arithmetic rather than asking you to take its word.
- A payoff plan from your real balances, rates and minimums, with the date each debt clears
- A buffer sized to how secure your income is, not to a round number
- Which account your next dollar belongs in — HSA, Roth, Traditional, 401(k), taxable
A tick means read off the account. A question mark means worked out, and worth your checking — a wrong rate reorders everything below it.
The curve steepens where the buffer finishes filling and its money rolls onto the balance.
The mechanic
Clear a debt and its payment doesn't become spending money.
It flips straight to the next line. Auto-reverse — you're told, not asked. It is the one thing that decides whether a payoff plan finishes in three years or eleven, and it happens without you remembering to do it.
The student loan at 4.50% is deliberately left alone. Under about 7% it keeps its minimum and runs its term, because paying it faster would cost more than it saves — and the app says so on the screen rather than quietly doing it.
Side B — Let it run
Then a portfolio that mostly leaves you alone
The shaded band on that screen is ±5 points. Inside it nothing happens, because trading costs more than the drift does. Two holdings are outside it here, which is what a reason to act actually looks like.
Tapedeck doesn't pick the holdings. They're yours, shown against the targets you approved.
Checked weekly. Acted on roughly once or twice a year.
Four decisions, and no others
Most investing apps are built to give you something to do.
This one is built to tell you when there is nothing to do — which, most months, is the truth.
The part most apps leave out
We went looking for an edge. There isn't one.
166 trial variants across the whole research programme. 96 of them were attempts to find an edge in picking or timing. None of the 96 found one.
Attempts · no selection or timing edge found
Everything here was tested honestly and did not survive:
So Tapedeck is built out of what was left — the returns that need no forecast. Clearing a card at 24.99% returns exactly 24.99%. Funding the right account first is arithmetic. Neither asks the market to do anything.
Those 96 ran before we built the registry, so they're logged as what they are — results without a hypothesis written down first. Of the ledger's 23 entries, 7 are pre-registered; everything since July 2026 works that way.
Where this actually stands
Version one tells you. It doesn't trade for you.
Placing orders in someone else's account is a different regulated business from advising them, with a slower and heavier registration behind it. So execution came out of version one and the advice stayed in.
Auto is still on the screen, and locked, because hiding where the product is going seemed worse than showing you a door that doesn't open yet.
Built, designed, pending
Since honesty is the whole pitch, here's the build status.
Tapedeck is pre-launch. You're joining an early-access list, not opening an account today.
Early access
Press play on the boring version.
The one that doesn't promise to beat the market, doesn't want your attention every day, and shows you a receipt for exactly what it did. Most months the right answer is nothing, and it will tell you so.
