WrenchTime is two apps in one: the logbook that remembers every service, fill-up, and mile for your car or motorcycle, and, with an OBD-II adapter, a live window onto the engine while you drive. • YOUR WHOLE GARAGE, ORGANIZED Every car and motorcycle with photos, odometer, license plate, engine type, and full history. Petrol, diesel, hybrid, or electric, all of them fit. • NEVER MISS A SERVICE Schedule maintenance by date or by mileage and get reminded before it is due. 58 procedures, from oil changes and brake pads to chain lube and tire rotations, each with cost, odometer, and notes. • LOG EVERY FILL-UP AND CHARGE Record fuel and EV charging with volume, energy, cost, and location, and WrenchTime works out your real economy and running costs on its own. Snap a pump display, a charger, or a receipt and on-device AI reads the numbers, nothing leaving your iPhone. • READ THE CAR WHILE YOU DRIVE Pair a Bluetooth OBD-II adapter and WrenchTime reads the engine live: revs, speed, engine load, coolant temperature, fuel rate. Every channel is recorded for the whole drive and kept with the trip, to scrub back through on a chart. • WRENCHTIME LIVE A full-screen dashboard for the road: revs, temperatures, fuel level, speed, lean angle, G-force, compass, altitude, a live map, trip stats, and weather, on a board you build. Several pages, seven card shapes, one layout per orientation, every widget drawn as a real instrument with colored bands past the normal range. • TRIPS THAT RECORD THEMSELVES Trips log themselves with GPS routes, and your car stereo over Bluetooth starts and stops them. Routes follow the roads you actually drove, and you can join two trips that were really one, or cut one that was really two. Then watch one back in 3D: a chase camera over satellite terrain, live gauges, and a short vertical video to share. • ON CARPLAY AND ON YOUR WRIST CarPlay gives you gauge grids for your adapter's readings and your last ten drives, arranged the way you read them. Apple Watch shows what is due and logs a fill-up, a charge, an odometer reading, or where you parked, plus five complications. • KNOW WHAT IT REALLY COSTS 31 charts: spending by category, fuel economy over time, cost per mile, and more. • MORE - Home Screen and Lock Screen widgets for spending, service, parking - Live Activity and Dynamic Island while you drive, on CarPlay too - Find my car, Siri, Shortcuts, CSV and PDF export, iCloud sync, iPad - Your units: km or miles, liters or gallons • FUEL AND CHARGING PRICES NEARBY Price Radar plots the stations around you by real direction and distance, cheapest one highlighted, one tap to navigate. Prices come from official public registries, so here is exactly where that works today: - Italy, France, and Spain: real prices straight away, nothing to set up. - Germany: real prices with your own free Tankerkönig key, entered once in Settings. - Everywhere else: the stations around you, from Apple Maps, without prices. Charging points are the exception, and work worldwide. Switch the radar to EV and it finds them anywhere, with the connectors they carry, how fast they are, who checked in last, and when it was verified, matched to the connector your vehicle holds. • FREE AND PRO Free covers 1 vehicle, 3 fuel, 2 care, and 3 charging entries a month, 10 trips a week, 1 chart, and 3 Live widgets. WrenchTime Pro lifts every limit and adds trip maps, all 31 charts, every widget, AI auto-fill, CarPlay, and Apple Watch. Try it free, then subscribe monthly or yearly, or buy once with a lifetime unlock. Your data stays yours. WrenchTime syncs only through your private iCloud account and never sells your information. ------ Privacy Policy: https://wrenchtimeapp.com/privacy/ Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula

Check engine light on? Find out whether it's serious before you book a shop visit or drive another mile. OBD2 Ninja reads your car's codes and rates every one Fix Now, Fix Soon, or Monitor for your year, make and model. Then it tells you what to check first. $0.99 once. No subscription, no account, no ads. OBD2 Ninja carries Apple's "Data Not Collected" privacy label, and everything works offline. In a parking garage, on the shoulder, with no signal at all. IS IT SERIOUS? Every code gets an urgency rating, not just a definition: • Fix Now: stop driving or get it looked at today • Fix Soon: safe to drive, book it this week • Monitor: keep an eye on it Plus what usually causes it on your specific vehicle, and the cheapest thing to check first. READY FOR EMISSIONS? See all eight readiness monitors at a glance before you go to the test station. Know whether you'll pass, or how many more miles of driving you need, instead of paying to find out. READ AND CLEAR • Stored, pending and permanent codes • Freeze frame data captured when the fault tripped • Clear codes and reset the light after you fix it • Confirm the fix actually held LIVE DATA Watch coolant temp, fuel trims, O2 sensors, RPM, load and timing in real time. Pin down an intermittent fault the parts-store scanner can't see. WHAT YOU NEED Any ELM327 Bluetooth LE or Wi-Fi adapter, and a car built 1996 or later (2001+ petrol / 2004+ diesel in the EU). Tested and confirmed with: Carista, Vgate iCar Pro BLE, OBDLink MX+. Full list and setup guide at ninja-obd2.com. WHAT IT DOESN'T DO OBD2 Ninja reads the engine and emissions systems that every car is required to expose. That is what turns your check engine light on. It does not read ABS, airbag, transmission or body-module codes, and it can't do dealer-level coding. Those need manufacturer-specific tools. We'd rather tell you that now than after you've paid. PRIVACY No account. No sign-up. No analytics. Nothing leaves your phone. Apple's own privacy label on this page reads "Data Not Collected." Check it.

Verdict
The clearest difference is price: WrenchTime at Free against OBD2 Ninja's $0.99. WrenchTime also leads on device support (3 vs 1). OBD2 Ninja's advantage is in-app purchases (none vs 4) and iOS requirement (18.0 vs 26.0). On update cadence and ads there is nothing between them.
