InstaVoice itself is like WhatsApp, except it emphasises the voice aspect plus the ability to chat with people that don’t have InstaVoice. I did install it and frankly found an anti-WhatsApp in terms of simplicity. And the main feature I’d probably use it for – the voice messages – are a feature in every popular IM app. Add to that the fact that no one in my address book has it and you have the lonely world that WeChat is. There’s the feature to send to other networks (SMS included I think) but this ability is not easily understandable from the user interface. Or maybe I’m now conditioned to want everything to be a straightforward as WhatsApp. Maybe I’m not alone.
