Get Dial Launch old version APK for Android
Nummer kiezen, Launch App
Dial a number, and app launches.
This app lets you launch phone apps by dialing per-defined numbers, it is useful if you have apps hidden from launcher (you don't want others to see), or you have too many apps installed and just don't want to spend time looking for them.
Important: It does not cost any money, dialing a number only launches corresponding app, it will not really reach telco network.
