“No Thanks” App

Why is the “No thanks” app not available on the App Store?

The app either hasn't been made available by the developer on iOS or it wasn't approved under Apple's TOS. We're just other users here and can't say for sure why an app isn't available.

Thank you. Do you know of a way to check if an app wasn’t approved or is waiting approval?

Only the app's developer can do that. So, once again, the advice is to contact them.
