The Android app is the one thing that isn’t ready yet. Leave an address and we’ll email you once, when the test opens. Everything else is available today, so create an account and start spotting.
Already available
The iPhone app went live on 4 September 2026, and Linesider runs in the browser on a phone as well as a desktop, where you can add it to your home screen. Everything syncs, so anything you record on one is waiting for you on the other.
