Slate has said the truck should start reaching customers later this year, so the app would most likely become available around the same launch window or close to deliveries. I couldn’t verify a separate public app release date from the available reporting, so the safest answer is: later in 2026, likely tied to truck deliveries.

What the reporting says

  • Slate Automotive will begin delivering its electric truck later this year.
  • Coverage from the launch event points to a Q4 2026 production launch.
  • Recent reporting also notes privacy-focused design choices, including a vehicle app that appears to be limited in what data it collects.

Practical takeaway

If you’re asking about the app specifically, there’s no clearly published standalone launch date in the sources I found. The most likely timing is near the first customer deliveries in late 2026.

TL;DR

The Slate Auto truck app is not shown with a separate public release date yet, but it likely arrives when the truck starts delivering later in 2026.
