Hi - Instant Messenger

I like this app I got it on my iPod touch 4th gen it amazing on texting calling but video chatting it crashing before the ( who ever your chatting with ) can answer I was kinda bumb out on that tho other then that it works great it goes really fast if your switching tabs I like how it tells you when someone typing if it been sent, delivered and read its just the video chatting I wish it would have worked if they fix that then it be a perfect 5 stars

It wasn't sending my messages and now it won't let me log in.

The Hi app will use your cellular network to make calls unless you specify to only use WIFI with the "call out" feature, BUT it's never actually worked for me. It gives me the error message "someone is already using this account", which makes no sense. The "Hi Team" seems like they would be friendly, if they were actually real. One option in to utilize their chat to get help with the app, but I've asked for help several times over the past week and a half without so much as one response. The only "help" offered to me when I tried to research my problem was an offer to pay money for more credits. -which probably wouldn't have worked anyway! Terrible app. Terrible service.
