Central Brain keeps track of everything at home that drives, heats or gets paid β your cars, property, bills and subscriptions in one place, with an AI assistant that runs entirely on your phone. CARS & EVS β’ Service intervals by make and model β for EVs including tire rotation, brake fluid and battery checks β’ Vehicle inspection, highway vignette, insurance and tire changes with reminders β’ Odometer with a smart mileage estimate β’ Service history with costs, and a fuel log with consumption stats β’ Scan documents with the camera: VIN, plate and tire size fill themselves in β’ Keep vehicle documents (registration, invoices) in one place HOME & PROPERTY β’ Statutory inspections β chimney, gas boiler, electrical, lightning rod and more β with intervals and reminders β’ Attach the inspection report as a photo or scan β’ Property tax dates and technician contacts BILLS & SUBSCRIPTIONS β’ Czech QR payments (SPAYD) β pay with one scan from your banking app β’ Recurring bills with reminders, swipe to mark as paid β’ A payment calendar β the whole year month by month, so you know in advance when the big one lands β’ You decide what "a month" means: an even average, or only what genuinely falls due that month β’ Subscriptions with monthly and yearly totals and price history β’ Costs in CZK, EUR and USD RECEIPTS AND WARRANTIES β’ Photograph a receipt and the shop, date and amount fill themselves in β’ Search understands several words at once β "shoes Decathlon 2026" finds it β’ It tracks the warranty and tells you before it runs out β’ Claims: days at the seller are added to the warranty end date β’ A photo of the item, its serial number, and who you bought it for AI ASSISTANT β’ Ask: "What needs service?" or "How much do I pay this month?" β’ It creates payments, logs services and finds answers in your data β’ Runs fully on-device (Apple Intelligence) β nothing is sent to any server AND MORE β’ Home Screen widget with what's coming up β’ Siri Shortcuts ("What's due?") β’ App lock with Face ID β’ No account, no sign-up β works right after install BUILT FOR CZECHIA The deadlines and intervals follow Czech rules: 24 months for a consumer to report a defect (Β§ 2165 of the Czech Civil Code), with that period suspended while a legitimate claim leaves the item unusable, and inspection intervals from local regulations (chimney yearly, electrical every five years, lightning rod, sewage treatment and more). They are defaults β every date and every interval can be changed, so the app works elsewhere too. It is not legal advice. Your data stays on your phone. With Premium it syncs through your own iCloud between iPhone and iPad, and you can share it with one household member. The free tier shows a single ad banner on the dashboard; Premium removes it. Premium is an auto-renewing subscription (monthly CZK 149 / yearly CZK 1,490) or a one-time Lifetime purchase (CZK 2,990). Subscriptions renew automatically unless canceled in your Apple ID settings at least 24 hours before the end of the current period.

Verdict
The clearest difference is ads: Marketlog at none against Central Brain's shown. Marketlog also leads on iOS requirement (15.0 vs 26.0). Central Brain's advantage is update cadence (every 3 days vs every 2 weeks). On price, in-app purchases and device support there is nothing between them.
