Pretty shoddy, wouldnt rely on for professional use
Use this for work on a 6th gen iPod touch. Disconnects all the time even after 3.12 update. Also transmissions are garbled half the time and indecipherable. Can be responding to a call while holding button down and all of a sudden app stops transmitting your call like you let go of button. Can also get a call, try to respond, and then have Zello completely disconnect. Bluetooth headset and push to talk button (Coda Click) seem to disconnect randomly as well.
All in all this app is a good idea but poorly executed. Maybe its better on a device with a cellular data connection? Id assume that only fixes the network connection issues though.
UPDATE: Ive had to switch over to using this app on my personal cell phone now with a data connection to get any sort of reliability from this app. At this point Im 100% certain it should not be used in professional/commercial environments. Communication in my line of work is too important to base off some shoddy app instead of purpose built radios. Maybe this app is great to call your kids for dinner, but for my use its 1 star all the way.
