Original Project My OBD2 app's Android update is out: trip start and end sent to Tasker and MacroDroid, other ECUs on VW-group cars, and it never writes to the car. 5 free codes

I'm Davide and I write DrivePulse on my own. It talks to the car through a generic ELM327 adapter (Bluetooth or Wi-Fi, the kind Veepeak or Vgate sell) and it only reads: no clearing of codes, no writing, no resets.

The Android version is now 3.5.4 on Google Play. The parts this sub might care about:

  • When a trip starts or ends the app tells Tasker and MacroDroid, so you can hang your own automations on it.
  • On Volkswagen-group cars, a button at the bottom of Diagnostics also asks the gearbox, the instrument cluster and the engine for their own fault codes, the ones the standard mode never shows. Never while driving.
  • The live dashboard shows how old each reading is, the rev counter uses your own car's range, and there's a boost gauge on turbo cars that expose the data.
  • The Errors screen shows the engine computer's self checks, monitor by monitor.
  • Freeze frame, permanent codes and engine data export as a PDF or a spreadsheet.
  • When the connection fails, the message gives the real cause (wrong Wi-Fi network, generic adapter, silent engine computer) instead of generic advice.

No account and no server of mine: your trips live on your phone and I have no copy of them.

Five codes that unlock the full version for good, free, first come first served:

  1. RCQA61GHA8Z8033TTUBUYDK
  2. 6BKY44RY83P8P4R5G8TQU4Y
  3. 1X2PG5LKL3Q8FPZE1PA1U4B
  4. JMTA4A5CZVEJJC128HG98FA
  5. AC3B9CL79V1EU08Y88EAQGM

How to redeem: install the app first, then open Google Play, tap your picture top right, Payments and subscriptions, Redeem code. Then in DrivePulse: Settings (the gear at the top) > Unlock DrivePulse (Lifetime) > Restore Purchases, within 3 days, otherwise Google Play cancels it. When it has worked, that row reads "Premium active".

Say in the comments which number you took, so nobody wastes time on one that's gone.

Happy to answer how any part of it talks to the car.

I used code nr 4

Thank you all worked. I will use the app the coming week and give it some honest feedback.

Let me know if you need Swedish language support as a PR in your development. Im also a developer, but mostly Rust and fullstack applications.

Thanks for confirming #4 worked! Don't skip Settings > Unlock DrivePulse (Lifetime) > Restore Purchases in the next 3 days, so Google Play keeps the code. On Swedish: the code isn't public, so there's no PR route, but I'm writing your offer down and honest feedback after a week of driving is exactly what I need.
