Questions.

What do I need?

An Android phone on Android 8.0 or newer and an ELM327 OBD‑II adapter. Check your bike’s connector first: many bikes need an adapter cable. To sign in the first time, you also need an internet connection and a Google account or an email address.

Does it work on iPhone?

Not yet. Tachline is Android only for now.

Where does my data go?

When you sign in, your email address goes to our sign-in service. What the app reads from your bike stays on your phone unless you send it. No ads, no analytics.
