Google Play release status: in review
Sketchmate's Android release has been submitted to Google Play Production review. The public Play listing may show "Not Found" until Google approves and publishes the release.
Once Google publishes it, this same Google Play package link should become installable for Android users in the selected launch countries and regions.
You can share https://sketchmate.net/android now. It will stay useful before and after Google Play approval.

If that direct Play link shows Not Found, Google has not published the listing yet.
