Here are a few of the most interesting Voxer statistics and facts I was able to dig up including user counts. As always, be sure to check back in the future as I will be updating this post as new and updated stats become available.
What is Voxer?
Voxer is a free app that combines the best of voice, text, photo and video messages for a powerful and personal messaging tool. Easily and instantly communicate with friends, family or teams at work – live or later. Voxer works over any 3G, 4G, or WIFI network in the world. Voxer is the only service that delivers voice live – so it can be listened to immediately – and simultaneously records the message – so it can be listened to later. (source)
