Thermal for iPhone

Every account. Every dollar. In your pocket.

Thermal for iPhone is not a thin companion to the web app. It is the same product on a smaller screen: the envelope budget, every transaction, the whole portfolio, and the 10,000-path retirement engine, all reading the account you already have.

Thermal on iPhone

Real screens, not mockups. Daniel and Mara Hale are a demo household with a net worth of $1,552,820, but every phone on this page is the actual iOS build and every number is the engine’s own output. Light and dark are the same screens captured twice in one sitting.

What's Inside

Tap the flame, and the rest of it is there

Four screens stay one thumb away in the tab bar, and you pick which four. The flame in the middle opens everything else, grouped the way the app groups it.

Daily Money

Assign the money while you are still in the aisle

Ready to Assign, targets, auto-assign, rollover, and the activity log all made the trip. Move $40 from Travel to Groceries at the checkout and the web app has it before you reach the car, because both are reading the same live data.

Prefer a simple monthly limit per category? That is the Simple view button at the top of the capture, one tap away, and switching does not cost you your history.

How the budget works
The Thermal portfolio on iPhone: $1,246,091 across 26 holdings, an all-time gain of $360,067 at 40.64%, a separate crypto reading for the last 24 hours, and the portfolio value chart belowThe Thermal portfolio on iPhone: $1,246,091 across 26 holdings, an all-time gain of $360,067 at 40.64%, a separate crypto reading for the last 24 hours, and the portfolio value chart below

Investments

Every account you own, added up on one screen

Every brokerage, 401(k), IRA, HSA, and crypto holding consolidates into one portfolio with time-weighted returns, so the number you see is market performance rather than the money you added. The capture is the Hale household’s: 26 positions worth $1,246,091, up $360,067 all time.

Crypto carries its own 24-hour line, because it is the only thing on the screen still trading while the markets are closed. And any holding opens into the whole security, which is the next screen down.

How investment tracking works
A holding opened on the Thermal iPhone app: NVIDIA at $100,048 across three accounts, with a year of price history, dividend markers, share count, average cost, and unrealized gains split long-term and short-termA holding opened on the Thermal iPhone app: NVIDIA at $100,048 across three accounts, with a year of price history, dividend markers, share count, average cost, and unrealized gains split long-term and short-term

Investments

Open a position, not just a portfolio

Tap a holding and the phone gives you the whole security: a year of price history with the dividends marked on it, a candlestick toggle, share count, average cost, and the long-term and short-term split on unrealized gains.

The capture is the Hale household’s NVIDIA position: 520 shares across three accounts, worth $100,048, with the account breakdown further down the same screen.

How investment tracking works
The retirement screen on iPhone: a 94% success gauge marked on track, 10,000 Monte Carlo paths surviving to age 92, the named base plan, and tabs for Social Security, healthcare, and tax planningThe retirement screen on iPhone: a 94% success gauge marked on track, 10,000 Monte Carlo paths surviving to age 92, the named base plan, and tabs for Social Security, healthcare, and tax planning

Retirement

A real engine, running on the phone in your hand

Not a retirement calculator with three inputs. The capture is 10,000 Monte Carlo paths against the Hale household's actual accounts and actual spending, 94% of them still funded at age 92, with Social Security, healthcare, and tax planning each carrying their own tab. Refresh it on the phone and it re-runs there.

How the retirement engine works
The Bridge on the Thermal iPhone app: the fan of 10,000 retirement paths, the categories ranked by how much they move the date, and the what-if chips that reprice the projection while you watchThe Bridge on the Thermal iPhone app: the fan of 10,000 retirement paths, the categories ranked by how much they move the date, and the what-if chips that reprice the projection while you watch

The Bridge

This month, priced in months of freedom

Because one app holds your spending and your retirement plan, it can quote one in the other’s units. What Moves Your Date ranks your categories by what trimming them does to your retirement, and the what-if chips re-run the projection while you watch.

On the capture, a $1,150 monthly surplus, invested and held, is 11 months of earlier retirement. That is the sentence a budgeting app on its own can never finish.

Why the Bridge exists
The cash flow screen on iPhone: the cash position with a 90 day outlook built from scheduled events, current and ending balances side by side, and the upcoming salaries, mortgage, and subscriptions listed under the day they landThe cash flow screen on iPhone: the cash position with a 90 day outlook built from scheduled events, current and ending balances side by side, and the upcoming salaries, mortgage, and subscriptions listed under the day they land

Cash Flow

The next 90 days, before they happen

Thermal already knows your salaries, your mortgage, and your subscriptions, because it found them recurring in your transactions. The cash flow screen plays them forward: the balance you will end the window with, and the day the balance dips lowest, named ahead of time.

Thirty, sixty, or ninety days out, with every scheduled event listed under the day it lands. The surprise bill stops being a surprise, because it was on this screen three weeks before it hit the card.

How Thermal tracks your money
The goals screen on iPhone: a kitchen remodel 62% funded at $52,400 of $85,000, and a family Japan trip 78% funded at $18,600 of $24,000, each with its own progress barThe goals screen on iPhone: a kitchen remodel 62% funded at $52,400 of $85,000, and a family Japan trip 78% funded at $18,600 of $24,000, each with its own progress bar

Goals

Name the thing you are saving for

A goal is a number with a name on it: the Hales are 62% of the way to a kitchen remodel and 78% of the way to Japan, and the screen holds the running total, what is left, and the progress of each.

Add progress from the phone the day the transfer clears, and the same bars move on the web, because both are the same account.

How the budget works
The receipts screen on iPhone: five scanned receipts from Whole Foods, Target, Amazon, Costco, and Trader Joe's, every one matched to its card charge, with the scan button on topThe receipts screen on iPhone: five scanned receipts from Whole Foods, Target, Amazon, Costco, and Trader Joe's, every one matched to its card charge, with the scan button on top

Receipts

The paper receipt becomes line items

Photograph the receipt at the register and Thermal reads the line items, then matches the receipt to the card charge when it posts. The capture shows five receipts, every one matched to its transaction.

The point is the grocery run: one $180 charge is not one expense, and item-level receipts are how a long haul splits across categories without typing any of it.

More on daily money

On The Device

The parts the browser cannot do

Two widgets for the home screen

Cash Flow shows the month's income, spending, and what is left, in the small or medium size. Recent Transactions lists the latest activity in medium or large. Both read your live data, so the answer is on the lock screen before the app opens.

Face ID or Touch ID on the door

Turn on biometric unlock in Settings and the app asks for your face or your thumb, not your password. It is a toggle, not a requirement, and it never replaces the account you signed in with.

Sign in with Apple, or a passkey

Sign in with Apple and Google are both on the sign-in screen, and the app shares its sign-in domain with the website, so the credential you saved on one is offered on the other.

The camera is the receipt scanner

Photograph the paper receipt at the register, or pull an image out of your library, and Thermal reads the line items and matches them to the card charge when it arrives. Long grocery receipts split across categories by item.

Alerts worth a buzz, and only those

A budget going over, a transaction larger than the threshold you set, a bank connection that needs re-authenticating, a subscription whose price stepped up. Every category is a switch, per channel, in Settings.

Getting Started

Three steps, and only one of them is on the phone

Start your account on the web

Thermal accounts are created at thermalfinance.com. The trial runs 14 days with full Pro access and takes no credit card.

Connect your accounts once

Banks, brokerages, cards, and crypto link through Plaid, read-only. Thermal can see balances, transactions, and holdings, and can never move money.

Sign in on the iPhone

The app is a sign-in, not a second account: everything you connected is already there, on the same live data. There is nothing to buy inside the app and nothing to set up twice.

The iPhone app is in its final round of testing before release. Thermal is fully available on the web today, and the download link arrives on this page the day the listing does.

Security

Bank connections run through Plaid, the same infrastructure behind Venmo and Robinhood, and they are read-only. Thermal never sees or stores your bank credentials, encrypts your data with AES-256 at rest and TLS in transit, and never sells it.
