Open the Kosher Qin Phone app and go to the Account tab. Your app version is shown there (for example, “4.0.3 (20260920)”).

This is different from the phone’s system build number, which is in Settings → About.

The latest version at the time of writing is 4.0.5. It fixed several problems, including approved apps not showing up, the store showing the wrong list, and the app closing on open. If an app isn’t showing in your store, updating to 4.0.5 or newer is the first thing to try.

To update: Kosher Qin Phone app → Updates tab → the Kosher Qin Phone app update appears at the top → Update. Swipe down to refresh if you don’t see it.

If you don’t see an Account tab, your phone is on our older system. See “Is my phone on the 2.0 system?”
