Answers to the common questions, and how to reach us.
What do I need?
An Android phone on Android 8.0 or newer and an ELM327 OBD‑II adapter. Check your bike’s diagnostic 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.
How do I join early access?
Join the Google Group with the Google account you use on the Play Store, open the testing link in the group, tap “Become a tester”, then install Tachline from Google Play.
It won’t connect. What should I check?
Tachline shows which link failed. If it’s the adapter: check its light is on and no other app is connected to it. If it’s the bike: turn the ignition on and set the kill switch to run.
Will it read my bike?
It reads the standard OBD‑II data your bike’s ECU reports and shows you the list once connected. Maker-specific data such as gear position or ABS isn’t supported yet.
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. See the privacy page.
Email support@kindavishal.dev with your phone model, Android version, adapter and bike. Early access testers can also post in the Google Group.
