The original title for this post was “iSH Shell Launches on the App Store” which is significant since the project had previously spent several years on TestFlight.
Since the domain is apps.apple.com, that part is implied. (From the HN guidelines: "If the title includes the name of the site, please take it out, because the site name will be displayed after the link.")
The bit about TestFlight is certainly interesting but the best way to communicate it is not via the title but via a comment in the thread...like you just did!
