And yes phone numbers might be ripe for abuse and spam, but so are usernames and email addresses. I'd wager the reason is that Google wanted to do less, but do it better. Launch the app and you're greeted with your face from the front camera on your phone (we've already established it might not be sexy), a white bottom overlay with a button, and an overflow menu on the top right.Once you've made a couple of calls, the bottom overlay will start populating with your most recent contacts. (You can't see me now, but you will in a while.) If you're a geek like me, the first thing you'll look for are the settings.To achieve the latter, you'll see that Duo activates both Wi Fi and data immediately every time the app is opened, to make sure that the latter is already connected and ready should the Wi Fi signal drop. Now you may tell me that most of my screenshots in this post have a rather bad resolution.How can Duo be so good when most of what you're seeing are pixelated images?Duo isn't trying to revolutionize video calls, it just wants to approach them from a more modern perspective, one that builds on our smartphone-carrying habits, our needs for immediacy, and our disdain for complexity.With just a couple of calls, Duo has proven to me that it can replace Skype on my phone and maybe even tempt me to use it instead of Whats App audio calls with certain friends.If you fail to answer, a missed call notification will appear on your phone and let you either call back or message (SMS) the person back.
Part of what made Whats App so popular as a messaging client, and then again as a Vo IP alternative, was the low-entry barrier (plus free price and multiplatform support).They're nested in the overflow menu, along with Help and Feedback, and there aren't many.You can set the phone to vibrate or not when receiving a call, limit mobile data usage, unregister your phone number in case you're switching numbers or don't want to use Duo anymore, see and manage your blocked numbers, and activate one of Duo's unique features: Knock Knock.Not because I to see them while I chat with them, but because the simplicity is there and it's enough to make me think twice before opening either app.But Duo isn't yet without its faults or missing features.
