Make, model, odometer and the currency and units you think in. A short tour shows you around, and a second or third car is a tap away.

Kratos XT is the logbook your car never came with. Record fuel, services, documents and costs in seconds, and it tells you what is due next. It all stays on your phone.
How it works
Add a record in a few taps and let Kratos XT do the arithmetic, the reminding and the remembering.
Make, model, odometer and the currency and units you think in. A short tour shows you around, and a second or third car is a tap away.
Fuel fills, services, expenses and documents. Photograph a fuel receipt or an insurance certificate and the form fills itself in, with the photo attached.
Reminders by date or by distance, estimated from your own driving pace, so the next service or renewal never sneaks up.
A look inside





Features
One place for the numbers, the paperwork and the dates, without a spreadsheet in sight. New in 1.7: electric cars and plug-in hybrids, trips and a mileage log for your taxes, income and profit, inspection checklists, hour meters, your cars on every device and the web, and 49 languages. Features marked Pro come with it.
Real consumption measured tank to tank, the fuel left in the tank as you drive, and what a km costs at today’s price.
Photograph the fuel receipt and the litres, price, total, date and station fill in. Read in the cloud or only on your phone, your choice.
Long-press the app icon to log fuel, scan a receipt, log a service or add an expense. On iPhone, just ask Siri.
What is due next and your fuel economy at a glance, on the home screen and, on iPhone, the lock screen too.
Built step by step: items, measurements like brake pads and tyre tread, cost and invoices.
Insurance, road licence and permits with photos or PDFs, and an alert before each one expires. Photograph one and the insurer, number and dates fill in.
By date or by odometer, whichever comes first, with estimates from your own driving pace.
If you like, a nudge when a fill-up is overdue by your own habits, and a summary of the car’s costs each month.
Parking, tolls, washes, fines and accessories. Everything else the car costs, filed in one place.
Total cost of ownership, cost per km over time, km per month and a next-service prediction.
For imported cars: follow shipping, port, clearing and taxes, and see the landed cost.
Multiple vehicles, any currency, kilometres or miles, and the consumption format you prefer.
From English, Swahili and Arabic to Hindi, Japanese and Swahili. It follows your phone, or pick one.
Bring your history from Fuelio, Drivvo, Fuelly, aCar, Simply Auto or any spreadsheet saved as CSV.
Back up to a file or restore on a new phone any time, and export to CSV. Automatic backup to your iCloud Drive or Google Drive and PDF export come with Pro.
Log charges in kWh at home or on the road, with km/kWh or kWh/100 km. Plug-in hybrids and gas conversions keep each energy’s economy apart.
Start a trip and GPS measures it; the route never leaves your phone. Business, medical and charity miles add up to a tax-ready log at your rate. Logging trips by hand is free.
Rides, deliveries or rent: log what the car earns and see its profit after fuel, services and costs.
Pre-trip, walk-around and handover checks with notes and photos. Write your own checklists with Pro.
Tractors, boats and generators counted in engine hours: services, reminders and economy per hour.
Sign in once and your cars stay the same on your phone and tablet, and at kratosxt.bond/app. Signing in stays optional.
Share a car with the people who drive it. Everyone logs to the same history, synced as they go, and you choose who can edit. Pro shares with everyone.
Selling? A clean PDF of the car’s services, odometer readings and latest measurements, straight from your own logbook.
Tread and pad measurements charted over time, with a heads-up before they reach the limit.
A 0 to 100 score for every car, worked out on your phone from its papers, services, brakes, tyres, battery and fuel economy, with the reason behind every point lost. Pro predicts the next service and parts at your own pace and alerts you when economy drops.
Ask about a noise, a warning light or a quote, or show it a photo, and get an answer grounded in your car’s own records. Nothing is sent until you ask, and conversations stay on your phone. Three questions a month free, 100 with Pro.
Kratos XT notices when you drive and records the trip, start to finish, with a live card on the Lock Screen while you go. Swipe each trip to business or personal, replay the route, or export it as a video.
Log a fill at the pump and the station is already filled in, from OpenStreetMap. Stop at a station on a tracked drive with under half a tank, and Kratos XT offers to log the fill in one tap.
Start a trip and the phone becomes a car’s own display: your car in 3D driving the real streets around you, buildings rising from OpenStreetMap with their windows lit, tail lights that flare as you brake, the road’s name and speed limit, a speedometer that turns red over it, and what is left in the tank and what the drive has cost so far. Turn it on its side for a dashboard mount. Afterwards, watch any kept trip again the same way, from behind the car, at up to 20 times the speed.
See any unpaid tickets on your plate: in Uganda straight from the Uganda Police Express Penalty Scheme, ticket by ticket, and in 59 more countries one tap from the official checker, with your plate ready to paste. Check any plate too, before you buy.
Private by design
No sign-up, no analytics, no advertising. Your car’s history is yours, and it stays on your device unless you back it up, export it, or share a car, when that car’s records sync only with the people you invite.

For imported cars
Bought a car abroad? Log each stage of the import, from shipping and customs to taxes and registration, with references and costs. Every shilling, dollar or yen lands in the car’s true cost.

Price
The logbook is free for good, with no ads. Kratos XT Pro is a single purchase, not a subscription: pay once and it is yours on that store account.
Everything you need to keep a car’s history.
Everything, for every car you own, for good.
Pro is bought in the app through the App Store or Google Play, and restores on a new phone with the same account. People who used Kratos XT before Pro existed keep everything they had.
FAQ
No. Kratos XT works on your phone, offline, from the moment you open it. There is nothing to sign up for. You sign in, with Apple or Google, only to share a car with family, and only reading a receipt in the cloud or syncing a shared car needs a connection.
Your records stay on your device. Automatic backups go to your own iCloud Drive on iPhone, or your own Google Drive on Android, never to us. When you scan a receipt you choose how it is read: in the cloud, where the photo is read by Amazon Textract and then discarded, or only on your phone, where it never leaves the device. Documents are always read on the phone. A car you share syncs with the people you invite, and diagnostics or feedback reach us only when you tap Send. Questions you ask the AI mechanic go to Google’s Gemini, with a summary of the car’s records but never its plate, chassis number or your name, and only when you tap send. See the privacy policy.
Turn on automatic backup in Settings → Data: iCloud Drive on iPhone, Google Drive on Android. Install Kratos XT on the new phone and, before you add a car, it offers to bring your latest backup back in one tap. You can also back up to a file from Settings and choose Restore from backup on the new phone.
Yes, your fuel fill-ups. In Settings → Data, import a file from Fuelly, Drivvo, aCar or Simply Auto, or any spreadsheet saved as CSV. You see a preview before anything is added, and fills already on file are skipped.
Yes. Pick any currency, kilometres or miles, and show consumption as L/100 km, km/L or mpg (US or UK). The app speaks 49 languages, from English, Swahili and French to Arabic, Hindi and Chinese.
The logbook is free, with no ads. Kratos XT Pro unlocks everything for a single payment of $9.99 (or the local equivalent), with no subscription. See Price, or visit support.
Yes. Open the car, choose Share this car and Invite someone. Everyone who joins sees the same history on their own phone, and you choose whether each person is a driver, who logs fills, services and costs, or a viewer, who only looks. Free shares each car with one more person; Pro shares with everyone.
Sign in to the same Apple ID or Google account, open Settings → Kratos XT Pro and tap Restore purchase. Pro is yours for good; there is nothing to renew.
Start with today’s odometer reading. Kratos XT takes it from there.
