I like the idea, but the app is buggy. The app would not stop transmitting in ptt mode. The only way to stop it was to end the app. It sometimes has a really long delay at times. Are you by chance checking local network first? It would be nice if you could remap hardware keys for ptt.

Hi Donald, Thanks for your input. We will investigate the bug. We will also add a Setting enabling remapping of hardware keys for PTT.

Hi! I love your app! I'd recommend this app to anyone. However, one of my other users isn't able to hear my transmissions, I'm not sure if it's because of her provider (Not important) her phone brand (Apple) or model (iPhone X) or just a software issue. If you can, please look I to this error, and repair it. My rating will not be affected if you can't. Thanks! Joshua Tidwell JR.

Glitch, won't load half the time. I don't think there is a team to keep this thing going anymore. 🤔
