All-in-One Mileage Tracker & Car Management App
Trip tracking, smart maintenance reminders, nearby services on the map, AI assistant, expense tracking — everything a car owner needs in one place.
5 Apps for 1 Car?
Today car owners juggle multiple apps just to manage one vehicle. We fix that.
Killer Features
Built for real car owners who are tired of switching between apps.
Trip Tracking
Start a trip with one tap from the Lock Screen, Dynamic Island, or let the app auto-detect driving. Track distance, duration, and classify as business or personal.
Smart Maintenance
Never miss an oil change, registration renewal, insurance deadline, or inspection again. Tracks by both mileage and date. Full maintenance history log.
Nearby Services
Find gas stations, parking, car washes, auto repair, tire shops — all on the map sorted by distance. Filter by category and navigate with one tap.
AI Car Assistant
Ask anything about YOUR specific car. Fuse locations, oil specs, warning lights — it knows your make, model, and year.
Expense Tracking
Log fuel, maintenance, insurance, parking, tolls, and more. Attach receipts with camera. Filter by category, view by month. Track every dollar.
Family Garage
Manage multiple cars, multiple drivers, shared expenses. See who drove what, when, and how much it cost. One household, one app.
Recall Alerts

Your Data is Safe
Privacy isn't a feature — it's our architecture. We designed HiAuto so that even we can't track you.
No Route Tracking
We never collect, transmit, or store your routes. The only thing we record is the trip distance — nothing about where you drove.
Car ≠ Owner
We never link a vehicle to its owner. Car data and account data are stored separately on isolated servers. A car only knows about itself.
Only Your Phone Knows
The link between your account and your vehicles exists only on your device. No one — not even us — can see which cars belong to you.
Frequently Asked Questions
Is HiAuto free?
Yes! HiAuto offers a generous free plan with 2 vehicles, 200 auto-tracked trips per month, nearby services on the map, tax report export (PDF/CSV), and 20 AI assistant questions per month. Paid plans start at $5.99/month for unlimited vehicles, trips, and AI features.
How does automatic trip detection work?
HiAuto uses your phone's motion sensors to automatically detect when you start driving. No GPS tracking of routes — only trip distance is recorded. Battery impact is just 2-3% per day. You can also start trips manually via Lock Screen widget, Dynamic Island, or an OBD-II Bluetooth adapter.
Is HiAuto IRS-compliant for mileage tax deductions?
Yes. HiAuto generates IRS-compliant mileage logs that you can export as PDF or CSV. Trips can be classified as business, personal, medical, or charity. All tracking modes (auto-detect, manual, OBD-II) produce valid mileage records for tax deductions.
Can I manage multiple cars and a family fleet?
Absolutely. HiAuto is a Swiss army knife for car management — whether it's a family garage or a small business fleet. The free plan supports 2 vehicles; paid plans offer unlimited. Share car access with family members via QR code and control exactly what each person can see — maintenance, expenses, trips, mileage, and recalls.
How does expense tracking work?
Log every car-related expense: fuel, maintenance, insurance, parking, tolls, car wash, and more. Attach receipts with your camera, filter by category, view monthly summaries, and export reports. Track every dollar across all your vehicles in one place.
Does HiAuto track my location or routes?
No. HiAuto never collects, transmits, or stores your routes. Only trip distance is recorded. Vehicle data and account data are stored separately — the link between your account and your cars exists only on your device. Even we can't see which cars belong to you.
