## What is CarOtter?

CarOtter: your car, decoded.

A light comes on. You describe it or type the code. CarOtter tells you what it means, whether you can keep driving, and what to fix first. It knows your car's make, year and latest readings, so the answer is about your car, not a generic one.

PLUG IN. SEE EVERYTHING.
Any Bluetooth OBD-II adapter turns your phone into a scanner.
• 45+ live readings, on gauges you arrange
• Trouble codes in plain words
• Trends across every drive
• A smog check before you pay for the real one

A LOGBOOK THAT KEEPS ITSELF
Scan a receipt and the fill-up or service visit is logged with cost and mileage. Real MPG, month by month. A reminder when the next service is due. One garage per car, as many cars as you own.

IN THE CAR, ON THE HOME SCREEN
CarPlay shows health, live readings and active codes while you drive. A widget shows the latest readings at a glance.

YOURS, AND ONLY YOURS
No CarOtter server. No analytics. No ads. Everything lives on your phone, and you can export or erase it any time.

The assistant runs on your iPhone with Apple Intelligence. Want a cloud model? Bring your own OpenAI, Gemini, Claude or Grok key. What you send goes to that provider and nowhere else.

FREE
No subscription. No in-app purchases. If you use a cloud model, that provider bills you for your own key.

GOOD TO KNOW
• Works with any car that has an OBD-II port, which is most cars since 1996.
• No adapter? Chat, the garage, service history and fuel logging still work.
• iPhone and iPad, iOS 16 or later. On-device AI needs iOS 26 with Apple Intelligence. Older phones can use a cloud key.

## Version history (last 4 releases)

### 1.3 — 2026-10-19

A cleaner Home, Diagnostics, Smog and Service. Each screen now opens on one status line and one next step, with the facts you check most at the top.

Nothing recorded while your phone is locked gets lost any more. Drives, trouble codes and smog checks captured on a locked phone are kept and merged in when you unlock. Custom gauges can no longer be wiped by a locked launch.

Deleting your chat history now clears it everywhere, including the open Chat tab.

Multi-car garages: each car's drives, insights and custom gauges stay with that car, and removing a car removes everything that belonged to it.

Adapter connection: a slow reply no longer lands on the wrong gauge, "Adapter not responding" stays on screen instead of vanishing, and tapping Disconnect stops scanning for good.

The widget updates without slowing the app down. Reminders, the dashboard, the widget and CarPlay now agree on service intervals, air filters included.

Service documents sent to a cloud model now also mask customer names printed under BILL TO. Storage totals in Your Data are accurate, and export includes drive history, timeline events and custom gauges.

### 1.2 — 2026-08-08

This update makes CarOtter more careful with your data.

• Removing a car now deletes all of its records: fuel, service, drives, and smog history
• Scanning the same receipt twice now warns you instead of doubling the visit
• Scanned service dates can no longer land in the future and hide overdue maintenance
• Fixed an issue where fill-up entries could stop saving until the app restarted
• Editing a record no longer changes values you didn't touch when switching between miles and km
• Costs in chat now show your local currency
• Faster, safer receipt scanning with clearer limits for large PDFs

### 1.1 — 2026-08-04

• Redesigned chat with a cleaner conversation view and a beautiful new reading experience
• New Smog tab: see all your readiness checks and know you'll pass before you test
• Optional web search for AI chat: get current recalls, prices, and part info (bring your own API key)
• CarPlay reliability improvements for day and night themes
• Fixes: the message bar stays put when typing, plus layout polish throughout

### 1.0 — 2026-07-30
