    Central Brain

    What do your car and home really cost?

    Inspections, insurance, mortgage and subscriptions in one place — with smart reminders, QR payments and on-device AI. Your data stays on your device, with no account and no servers of ours.

    In a few minutes

    How you keep your car and home in check

    1. Add what you look after

      A car, a flat or a house, tyre sets, recurring payments. Scan your documents and the app reads the VIN, the plate and the tyre size straight off them.

    2. The app watches the dates

      Service intervals, roadworthiness tests, chimney, boiler and electrical inspections, payment due dates. Reminders are scheduled on the device itself.

    3. Ask the assistant

      “When did I last have the inspection done?” The assistant runs on Apple's on-device models — neither your questions nor its answers ever leave the phone.

    4. With Premium, on every device

      Your data syncs through your own private iCloud and you can share it with your family. Without Premium everything stays local, with a backup export available anytime.

    Service, insurance and the household budget at a glance

    • The Central Brain dashboard: what you pay this month and what needs attention — service, oil and an approaching technical inspection (MOT).
    • The vehicle list in Central Brain — a BMW i4, a Skoda Fabia and an Octavia with their monthly costs and a warning about approaching dates.
    • A house detail in Central Brain: home insurance and property tax alongside chimney, gas boiler and electrical inspections.
    • Finance in Central Brain: payments by due date — mortgage, life insurance and savings, broken down by category.

    Features

    What the app does — from MOT to subscriptions

    Cars and EVs

    Service intervals including EV plans. MOT, motorway vignette, tyres, fuel logs and an odometer with a smart mileage estimate.

    Payments on cars

    Liability insurance, collision cover, road tax and a lease belong to the car. Every vehicle has its own payment overview with QR payment and reminders — and the costs feed into the price per kilometre.

    House and flat

    Statutory chimney, boiler and electrical inspections with reminders, contacts and scanned certificates.

    Czech QR payments

    Payments in the SPAYD format, cost overview in CZK, EUR and USD, and price history.

    Attachments on payments

    Add the contract, policy or invoice straight to the payment: scan it, snap a photo, or pick a file. The attachment syncs through iCloud and travels with your backup.

    Subscriptions in check

    Renewal dates and costs in one place, with icons for the most common services.

    Monthly totals everywhere

    Cars, properties, finance and subscriptions all show what they cost per month and per year, with expenses broken down by category. Semi-annual and annual payments count only their fair share.

    Hide amounts

    Showing someone your phone? Tap the eye next to the amount — they all disappear while names and dates stay readable. Turning the phone face down works too.

    On-device AI assistant

    Runs on Apple Intelligence right on your device. Your questions never leave the phone.

    No account, no servers

    No sign-up and no servers of ours. Data lives on your device; with Premium it syncs through your own iCloud, which we cannot see into.

    Document scanning

    The camera reads the VIN, the licence plate or the tyre size straight from a document.

    Family sharing

    With Premium you share household data through iCloud and can change anyone's role at any time.

    No surprises
