Instead of large tables, piles of papers, ridiculous records, during the maintenance and repair of your car. There must be something that will solve the issue of how to store the history of the effort expended. Grouping by mileage and work is only a small part of what the application can boast of. โ€ข Noticed a defect or want to record some information? - Use a comment indicating the mileage and date โ€ข Is it time to carry out maintenance? - For large-scale work, the maintenance screen will help you record all the data on the work performed โ€ข Don't want to write down the name of the part and its numbers every time? - The application can scan the history of used parts and offer you autofill โ€ข Don't want to remember how many kilometres you need to carry out maintenance? - The application will send you a notification about the upcoming maintenance. We taught it to calculate the average distance between services. P.S. But don't be upset if it doesn't send you a notification, maybe it needs a little more information โ€ข And of course, a graphical representation of the fuel consumption model, mileage per litre, a car mileage chart and many other interesting things in the future The application is based on a real car operation model, we tried to take into account most of the suggestions, make the necessary functions without overloading the design. Since it is impossible to take into account all requests, the development of the application will continue

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: โ€ข Fix Now: stop driving or get it looked at today โ€ข Fix Soon: safe to drive, book it this week โ€ข 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 โ€ข Stored, pending and permanent codes โ€ข Freeze frame data captured when the fault tripped โ€ข Clear codes and reset the light after you fix it โ€ข 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.
