The CalculatorAI Phone App — iPhone and Android

CalculatorAI is on the App Store and Google Play. It is the same product as calculatorai.app — every tracker, every calculator, every document generator and Grace, the AI assistant — rebuilt for the phone, signed in to the same account. What you record on the phone is on the website a second later, and the other way round.

The short version of why it exists: money happens away from the desk. You pay at a till, a client pays you in a café, a bill arrives on a Sunday. The phone app turns each of those into one sentence, one photo or one tap — and keeps the numbers that matter on your Home Screen, so you see them without opening anything.

• App Store: https://apps.apple.com/app/id6764784426
• Google Play: https://play.google.com/store/apps/details?id=app.calculatorhub
• The app's page: calculatorai.app/app

What you can do in ten seconds

These are the moments the app is built for. Each of them is real today.

• At the till: say "spent 45 on groceries" to Grace. She records it in the Income & Expenses tracker with the amount, category, date and the currency you usually use there. One tap undoes it.
• A receipt in your hand: take a photo. Grace reads the shop, the amount and the date and offers the entry to save.
• A client paid: "Anna paid invoice 104". The invoice is marked paid, and the money can go straight into your Business P&L.
• Morning check: glance at the Home Screen — portfolio, budget left this month, today's spending, the next payment due — without unlocking the app.
• A habit done, a bill paid, a debt payment made: one tap on a widget button or one Siri phrase.
• An appointment coming up: the next client or event counts down in the Dynamic Island and on the Lock Screen.

Grace and photo reading come with Pro (every new account gets 14 days of Pro free, no card). Widgets and their buttons, Siri shortcuts on iPhone and Quick Settings tiles on Android are free.

Grace in your pocket

Grace, the AI assistant, is the heart of the app. She is not a chat that gives advice — she does the work:

• Records anything in any tracker from a sentence, typed or spoken: an expense, income, a trade, a shift, a trip, a dividend, a reminder.
• Reads photos and documents: receipts, bank screenshots, statements, invoices, a broker's portfolio screen — into rows you check before saving.
• Answers from your own numbers: "Am I on budget?", "What did the rental make this year?", "Which trade was my best?"
• Changes, pays, closes and deletes records, always with an Undo.
• Speaks (on the Grace plan): answers read aloud in her own voice, and a voice conversation, in all ten languages.

On the phone she is one tap away from every screen, from a Home Screen button, from Control Center and Siri ("Ask Grace") on iPhone, and from a Quick Settings tile on Android. Before anything is sent to an AI service the app asks your permission, and you can withdraw it in Account settings; without it everything except Grace and the AI features keeps working.

Home Screen and Lock Screen widgets

There is a widget for every tracker except the Password Manager (a vault on a Home Screen would defeat its purpose), plus the workspace calendar and two one-tap buttons — Ask Grace and Scan a receipt. All of them are free.

• What they show: your portfolio with its chart, net worth, budget left, upcoming payments, habits for today, spending, savings goals, debts, loans, mileage, profit and loss, dividends, rental income, shifts, stock running low, clients, events, the trading journal, today's bookings, invoices due, QR scans, subscriptions and the calendar.
• Sizes: small, medium and, for the richer ones, large; on iPhone also on the Lock Screen (rectangular and inline, and circular where a single figure makes sense).
• Buttons inside widgets: tick a habit, mark a bill paid, add an expense. On Android ticking a habit happens right on the widget; on iPhone the button opens the app straight on that action.
• Hide amounts: one switch hides every figure on every widget — for a phone that other people see. On Android there is an eye right on the widget.
• Honest freshness: a widget shows the figures as of the last sync, with the time, so an old number is never mistaken for a live one.
• One look, one brand: every widget uses the same dark style, large figures, up and down arrows and a smooth chart, in your language and currency.

iPhone widgets need iOS 17 or later.

iPhone extras

• Siri and Shortcuts for every tracker: "Open a tracker", "Add" (an expense, income, a transfer, a calendar reminder, a note), and actions on one item — mark a habit done, pay a loan, pay a debt, top up a savings goal, mark a bill paid, log today's regular route. Shortcuts asks which one; nothing needs setting up first.
• Control Center and Lock Screen buttons (iOS 18): Ask Grace, Scan a receipt, Add an expense.
• Back Tap: tap the back of the phone twice to open Grace or add an expense (through Settings → Accessibility → Touch → Back Tap with a Shortcut).
• iPhone search: your trackers show up when you search the phone.
• Dynamic Island and Lock Screen live activities: the next client or event with a time counting down, the bills you pay by hand that are due today, and what Grace is doing while she reads a receipt or speaks. One island at a time, the nearest thing first. Automatic payments never appear there — it is for what needs you.
• Quick actions on the app icon: favourites, scan a receipt, ask Grace, and one action of your own choosing.
• Phone calendar subscription (Pro): your bookings or everything on the workspace calendar appear in the iPhone's Calendar app, with or without sums.
• Face ID or Touch ID opens the Password Manager on that iPhone.
• Sign in with Apple, including Hide My Email — and it can be linked to an account you already have, so it never creates a second one.
• Haptics that confirm a save, a delete and a switch.

Android extras

• Quick Settings tiles: Ask Grace, Scan a receipt, Add an expense — from the pull-down shade.
• Shortcuts on the app icon: long-press for the same actions.
• Themed icon that follows your wallpaper colours.
• A habit ticked right on the widget, without opening the app.
• Scrolling lists inside widgets (Android 12 and later), the eye that hides amounts, and a refresh button.
• "Right now" — an Android-only widget with what needs you today.
• A keypad on the add-expense widget and tile for the amount.

Never assume a feature from one list exists on the other phone: Siri, Control Center, Back Tap and the Dynamic Island are iPhone-only; tiles, the themed icon and ticking on the widget are Android-only.

Built for the phone, not shrunk to fit it

• Native navigation: a real tab bar, sheets that slide up, swipe actions on rows, a large title — it feels like the phone's own apps.
• Tablets and the foldable iPhone Duo: iPad and Android tablets get the trackers across the full width, with the tabs in a side panel. On iPhone Duo the open inner screen works the same way; folded, the tabs sit in the narrow strip beside the screen.
• Document scanner: the phone's own scanner straightens and crops a page before anything reads it. Scanning is free; reading it into a tracker is Grace, in Pro.
• Reminders at your hour: bills, renewals, rent, a goal falling behind and Grace's nudges arrive as notifications at the time you choose.
• Every calculator and every document generator is in the app too — and a calculator result can be sent into the matching tracker.
• Ten languages and any currency, the same as the site.

The app or the website?

Both, if you like — it is one account and one set of data.

The website can also be installed from the browser as a lightweight app (no store, almost no space). That is a different thing from the store app: the store app is the one with widgets, Siri (iPhone) or tiles (Android), and the camera.

Free and paid

• Free: the app itself, every tracker and calculator within the free limits, widgets, widget buttons, Siri and Shortcuts, Control Center buttons, tiles, the document scanner, the Password Manager.
• Pro: Grace, reading photos and documents, dictation, the phone calendar subscription, the Dynamic Island started by the site, shared books.
• Grace plan: made for talking to Grace every day — she stays at her smartest much longer each month, saves simple additions by herself with an Undo, and answers out loud in a real voice conversation, in ten languages.
• Every new account — made in the app or on the site — gets 14 days of Pro with no card. Afterwards it simply returns to Free: your data stays, nothing is charged.

Prices are on the pricing page.

Your data

• No bank login. The app never asks for your bank password and never reads your bank account. You decide what goes in.
• One account, two places: everything is stored on our servers and appears in the app and on the website. That is also why the app needs a connection: it does not keep your finances on the phone, which is safer on a phone that gets lost or shared.
• Two-factor sign-in works in the app as on the site.
• The Password Manager is end-to-end encrypted: it is unlocked on your phone; we cannot read it. On iPhone, Face ID or Touch ID unlocks it on that phone only.
• AI permission first: nothing reaches an AI service until you allow it.
• Export or delete. Every tracker exports its data as a file, free on every plan; the account can be deleted from the app's settings at any time.

What the app does not do

Said plainly, so nobody is surprised:

• It does not connect to your bank or import bank transactions on its own.
• It does not work offline. Reading and saving need a connection — a deliberate choice for privacy and so that nothing you typed is lost silently.
• It does not move money. "Pay" means "mark as paid".
• Grace gives no investment, tax or legal advice.
• Apple Watch, Wear OS and CarPlay apps do not exist.
• Siri cannot record a whole conversation with Grace without opening the app; the app opens and Grace listens there.

Questions

Is the app free? Yes. Download it free; the trackers, calculators and widgets work on the free plan within its limits. Grace comes with Pro, and every new account gets 14 days of Pro without a card.

Do I need a new account for the app? No. Sign in with the account you use on the website — email, Google or Apple — and everything is already there.

Which phones does it run on? iPhone (including the foldable iPhone Duo) and iPad from the App Store, Android phones and tablets from Google Play. Widgets on iPhone need iOS 17 or later; Control Center buttons need iOS 18.

Is there a widget for my tracker? Almost certainly: every tracker has one except the Password Manager.

Can Siri add an expense? On iPhone, "Add an expense" in Shortcuts or Siri, or a button in Control Center; on Android, the Add an expense tile or the icon shortcut. For a whole sentence ("spent 45 on groceries at Lidl"), ask Grace.

Does it work without internet? No. Your data lives on our servers, so the app needs a connection to read or save it.
