OBD2 Logger vs AutoMynded

OBD2 Logger turns your iPhone into a precision data logger for any modern car. Plug a Bluetooth ELM327 adapter into your vehicle's OBD2 port, pair it once, and stream live engine, hybrid, battery, and emissions data straight into per-session CSV files on your phone. No accounts. No cloud. No analytics. Your driving data never leaves your device. LIVE READOUT • 40+ standard SAE J1979 PIDs, automatically discovered from your car: RPM, vehicle speed, coolant temp, throttle, MAF, intake MAP, fuel trims, catalyst temperatures, and more. • Manufacturer-specific Mode 21 PIDs on profiled vehicles — including HV pack voltage, MG1/MG2 motor torque, and battery cell-block temperatures on Toyota/Lexus hybrids. • Values grouped by category (Engine, Hybrid, Battery, Emissions, Diagnostics) and updated every second. • One CSV per logging session, written into the app's Files container — open it in Numbers, Excel, pandas, DuckDB, or any other tool with no preprocessing. • Wide-table format: ISO-8601 timestamps, one column per active PID, blank cells where the ECU returned no data (no spurious forward-fill). • Smart-stop after extended idle so you don't end up with a tail of empty rows when you forget to tap Stop. WORKS IN THE BACKGROUND • Keeps logging while you drive with Maps in the foreground or the screen off, using Apple's standard background location mode for trip-tracking apps. The system location indicator is shown the entire time. We don't store your location. VEHICLE PROFILES • Ships with three profiles: a generic Mode-01 fallback, a Toyota hybrid family profile, and a 2020 Lexus RX 450h/450hL profile validated against a real vehicle. • VIN auto-read on connect; year, make, model, and trim pre-filled from NHTSA's free public vPIC API. • Import any third-party profile JSON to add coverage for your car. The format is documented and human-readable. DON'T HAVE AN ADAPTER YET? • Tap "Try demo mode" on the second onboarding step to explore the app end-to-end with synthetic data — no hardware required. WHAT YOU NEED • Any Bluetooth Low Energy ELM327 adapter (Veepeak OBDCheck BLE+, vLinker MC+, OBDLink, etc. — most BLE clones work). USB-only and Wi-Fi-only adapters are NOT supported. • A car with an OBD2 port (1996+ in the US, 2001+ in the EU). PRIVACY • Nothing is collected, transmitted, or stored on our servers — we don't have servers. The only outbound call the app ever makes is one VIN decode per vehicle to NHTSA's vPIC API. • Your CSVs and vehicle records live in the app's Files container, accessible to you in the iOS Files app under On My iPhone → OBD2 Logger. • Open source: github.com/NathanNam/obd2-logger

Snap any car concern. AutoMynded's powertrain-aware AI tells you what it is, how urgent it is, and what to tell a mechanic. Right answer for gas, hybrid, or EV. Most car maintenance apps were designed before EVs went mainstream. They tell Tesla owners to "change the oil" and Bolt owners to "replace the spark plugs." AutoMynded knows what your vehicle actually has and what it doesn't. Every diagnosis branches on whether you drive gas, diesel, hybrid, plug-in hybrid, battery-electric, or fuel-cell, so the answer is right the first time. WHAT AUTOMYNDED DOES Photo diagnosis in seconds. Snap a warning light, a fluid spot under the car, a worn part, anything. Add an optional one-line note. AutoMynded returns a severity rating (urgent, soon, or informational), a plain-English explanation, and the verbatim paragraph to send to your mechanic when you decide to call one. Smart service receipt capture. Snap a service receipt and AutoMynded extracts the shop, date, mileage, line items, and total. Confirm the pre-filled fields and save. Your service history builds itself. Powertrain-aware maintenance schedule. The schedule generates from your vehicle's powertrain. EV owners get tire rotation every 5,000 miles (tighter than ICE), 12V auxiliary battery checks every three years (the most overlooked EV failure point), battery coolant intervals, and software update reminders. Gas owners get the standard oil, plugs, transmission, and filter intervals. Plug-in hybrids get both with adjusted timing because the engine cycles less. Mileage logger with the live IRS rate. Track business miles for tax season. Manual entry on free, GPS auto-track on Pro. Each trip snapshots the IRS rate at save time so prior trips don't drift if the rate changes mid-year. Annual AI summary, Pro. Pro users get a per-vehicle year-end narrative covering total miles, top spending categories, recurring themes from saved diagnoses, and what to plan for next year. Cached on your device so re-opening is free. EV-specific surfaces, free. Charging session log, battery range tracking with a Swift Charts trend line, and OTA software update history. Available on every BEV and PHEV vehicle profile, no Pro required. EV awareness is the differentiator, not a paywall. Multi-vehicle for households, Pro. Free is one vehicle. Pro is unlimited, perfect for the gas commuter plus the EV daily. POWERTRAIN COVERAGE Gas, Diesel, Hybrid (HEV), Plug-in Hybrid (PHEV), Battery Electric (BEV), and Fuel Cell (FCEV). Pick once at vehicle setup. Every Gemini call after that adapts. PRIVACY Your vehicles, photos, diagnoses, receipts, and service history live on your device. There are no AutoMynded servers. Photos and your vehicle's make, model, year, powertrain, and mileage are sent to Google's Gemini AI for the diagnosis or extraction call, then the response comes back to your phone and stays there. For the Pro Annual Summary, only aggregated yearly totals are sent, never individual records. You can review and revoke AI access in Settings any time. Not a substitute for professional service. AutoMynded helps you understand and document. Always consult a licensed mechanic, dealership, or manufacturer warranty for repair, safety, or warranty decisions. PRICING AutoMynded is free for one vehicle, five photo diagnoses per month, and five receipt extractions per month. Manual service entry, manual mileage entry, and EV-specific features are unlimited on free. Upgrade to AutoMynded Pro for unlimited diagnoses and extractions, multi-vehicle support, GPS-tracked mileage, and the annual AI summary. $4.99/month or $29.99/year (about 50% savings). Subscriptions auto-renew until canceled. Cancel anytime via iPhone Settings, Apple ID, Subscriptions.
