What we ship, what's open, and what isn't. Today the answer is: apps are proprietary.

Status — 2026-07-31

iOS and Android builds are proprietary. Source is not published. The griptoad26/xkg-mobile repo on GitHub is a Flutter starter, not the shipped binary.

What you get

You get the iOS / Android binaries we ship to TestFlight and the Play Console. Both are signed with our distribution cert and reviewed before they go out. Free and Pro tiers as listed on the downloads page.

What you don't get

You don't get the source. Not for the Free tier, not for Pro. We're explicit about this because the alternative — a half-disclosed repo that drifts from the shipped binary — would be worse than silence.

Heads up: a public repo exists

griptoad26/xkg-mobile is a Flutter workspace we use to prototype screens, widgets, and experiments. The iOS / Android binaries we ship are built from an unreleased internal tree. Do not assume what lives in that repo is what runs on your phone.

Landing-page copy change

The mobile feature card on the homepage was promising an MIT-licensed open-source build. That was inaccurate and has been replaced.

Before

Mobile apps for iOS and Android. Open source under MIT — built with Flutter, available on GitHub.

After

Mobile apps for iOS and Android. Built with Flutter. Source is not published at this time — the shipped builds are derived from an unreleased internal tree.

Will this change?

Maybe. Two conditions would have to hold for us to flip it:

If both hold, the roadmap gets a real date. Until then, the policy is "source not published."
