Driviko — mileage & expense tracker with OBD engine data

Hey everyone,

Looking for feedback, especially from OBD users I have iOS + Android mileage and expense tracker that records trips automatically and uses an OBD dongle (BLE / Wi-Fi, ELM327-based) for engine data. Works without a dongle too — you just lose the engine-side data.

Maps & trip visualisation

Every trip is recorded automatically in the background and shown on an interactive map with the full route. You can scrub through the journey to see speed at any point, plus idle and waiting time, time spent in heavy traffic, average and max speed, and acceleration events. If a dongle is connected, the engine readings (RPM, load, oil temp, etc.) are overlaid on the same timeline so you can see what the car was doing at any moment of the drive.

What it reads from OBD

* Engine RPM

* Calculated engine load

* Engine coolant temperature

* Oil temperature

* Vehicle speed

* MAF (mass air flow)

* Engine fuel rate

* Fuel level

* Odometer

* Battery / control module voltage

* Ambient air temperature

Charts & exploration

Every reading has its own interactive chart you can scroll, zoom, and pan through. Charts are linked with the map — tap a point on the chart and the map jumps to that spot on the route (and vice versa), so you can see exactly where RPM spiked, where coolant climbed, or where you were stuck idling. Overlay multiple readings to compare them on the same timeline.

Reporting & export

Trips, expenses, and engine data can be exported as detailed HTML or PDF reports — full route, stats, and OBD readings included. Useful for keeping records, sharing a trip, or expense reports for business mileage.

Looking for feedback on:

1. Does the OBD connection work reliably for you? Adapter brand/model, your car, anything flaky?

2. General app feedback — UX, map / trip view, charts, stats, expense tracking, reports.
