Why is this app better than What'sApp/Viber/etc? Is it more reliable? I've always found these data messaging apps to be somewhat flaky.
I'm still looking for an iMessage replacement for Android - a completely functional SMS app which sends via data if available, reliably and invisibly. It should be able to send SMS to people who don't use the same app as well - I don't want a separate app for data and SMS messaging. GoSMS for android attempts this, but I find it often doesn't work, which is exactly the opposite of what I want for an SMS app.
edit: Looking at the app description, I can see why it's so popular. Free SMS to anyone within US and Canada is great (sadly, I'm in Australia). Perhaps the website should be clearer about the features?
