It's just re-branded RealPTT service. Subpar audio, horrible user interfaces, and although they show images of it working on various handheld radios it doesn't work on the ones we have tried. ### 3/5 — Great for keeping up with fast paced day to day with environment work or personal *2018-12-13* Excellent idea, great service but needs an app fix. Crashes persistently on IOS iPhone7, constantly shuts completely out of app back to login. I believe the connectivity issues may pertain to the functionality of Bluetooth connection ## Frequently asked questions about PTT4U ### What is PTT4U?
