Missing advertised feature (Ruby)
App falsely advertises support for Ruby, which is absent and labeled as 'coming soon' despite being marketed as available.

“No ruby — Advertises it has ruby. Got it for ruby. Ruby is 'coming soon'. It doesn't have ruby. 0/11”
“Promised Ruby support but it's not there. 'Coming soon' has been stuck for months. Deceptive marketing.”
“Downloaded app specifically for Ruby coding. No Ruby option exists. Fake advertisement.”
App fails to run code after ad prompt
Users cannot execute any code; clicking 'Play' leads to an ad prompt that does nothing, preventing execution even on sample files.

“Doesn't work — Won't run any file, even one of the sample ones such as Hello World. When I click the Play button to run any file, I then click 'view ad and run for free', and nothing happens.”
“Clicking play just shows an ad screen that never loads the code. No error, no response.”
“Sample programs don’t run. After tapping 'view ad and run', the app freezes or does nothing.”
