New feature: fast-change for channels

Callbox v2.0.2 is being released, which is an optional upgrade, but which brings 2 desirable features:

First, you can now flip around through channels much easier than before; we’ve added a fast change channel picker right on the main screen so that you can spin through the channel list and move to that channel directly – all with your thumb!

Simply tap anywhere in the channel info bar along the bottom of the main screen to bring up the fast-change picker – and tap anywhere in the info bar (or on the widget itself) to dismiss it. To use it, simply spin it to a different channel. The channel will change as soon as you […]

Quickstart with Callbox: all you need in 60 seconds!

Callbox is innovatively simple: it works just like a 2-way radio, where your phone is your handset.  There is no registration, no account to set up, no exposing your identity, no scanning your contacts.

If you haven’t downloaded the app yet, get the iOS Version from the App Store. Other versions are coming.

Here’s everything you need to be an experienced user in 60 seconds:

1. First time launched: Give us Permission

Like any iOS app, the very first time Callbox is launched, we must ask for permission to use various device services. We’ve tried to make it simple: just click each button and say “Allow.”  (Without these permissions, you won’t be able to use all our features.)

2. Get in a channel.

Welcome Callbox!

Big news: Our first application is now in the Apple iOS App Store!  But don’t look under Virtual Airwaves, because you won’t find it.  What you’ll find is:


Here at Virtual Airwaves, we have all kinds of ideas for using radio-style communication in today’s mobile world, and our TestFlight app has several such ideas poured into it.  In moving to a larger scale of use, we are segmenting different uses into separate apps, and our first app is Callbox (officially for App Store purposes the full name is Radio Callbox).

Callbox brings zero-registration, zero-administration private channels to public use.  You’ll recognize all the private channel features (including join codes, ringing, etc.) that you’ve seen before.  But […]

Try the “Echo” Channel

In case you don’t have any friends on the system yet, you can still test the system by yourself: just for fun, we have created the Echo Channel, a private channel with a special feature: normally you can’t hear yourself when you transmit; but with this special channel, anything you (or anyone else in your nearby vicinity) transmits will be repeated back over the air about 5 seconds later.

Like any other private channel, you will need a claim code to join it; for the echo channel, the claim code is the word “echo”! Go to the Channel List page, tap “Join”, and enter the 4 letters “e-c-h-o”.

Device Recovery, Without Accounts!

A key element of Virtual Airwaves ease of use is that it works just like any handheld radio device: there’s no account to set up, no sign-in or registration, no synchronizing; you just use it and it works.  This philosophy that each mobile phone/tablet is its own separate Virtual Airwaves device is highly practical: the different mobile phones and tablets that you own each have different uses (and often, different users), so with Virtual Airwaves, each device can have its own purpose, with its own collection of channels.

However, there are times when you need to change your phone, or your phone gets cleared, (or worse, you lose your phone…) — so how do you avoid losing that unique set of channels you’ve created and joined?

A standard, if heavyweight, […]

Our New Beta: What We’ve Learned, Part 2

“Ringing” users to initiate a conversation is clearly an essential function; Virtual Airwaves is meant to be lightweight and non-intrusive, so ringing must be the same.  With users managing more channels, we wanted to provide more control for sending and receiving rings.

New Ring Management Features

  • Ring Muting: Some channels are more active than others, and especially with a larger group, too much ringing could be distracting.   So now you can mute the ring, so that the ring alert will still appear, but it will not have an audible sound.   Or, you can even block the ring completely, which will prevent any rings for that channel from being sent to you. (If you are the owner of a channel, […]

Our New Beta: What We’ve Learned, Part 1

Over the holidays we released a major Beta version that, in addition to continuing improvements in audio quality and overall system stability, introduces a variety of new features which are motivated by how people are using Virtual Airwaves.

What we’ve learned is that Virtual Airwaves really is a unique mode of communication: quick, real-time interaction without the overhead of social networks, contact lists, recorded history, or administration. Our users described Virtual Airwaves as more spontaneous than a phone call, and less intrusive and permanent than a text message.

Consequently, people are creating more private channels than we imagined! Channels for 1-1 communication have proven to be useful as a fast method of contacting a partner or spouse directly.  As developers, we’ve been using a permanent 3-person channel: today we had a quick […]

New User Features in our 2nd Beta Release

Today, July 22, we’ve made our 2nd beta release (“build 12”) with lots of new features and fixes based on the great feedback we’ve received from the first release.  The theme behind this release could be called:

 “Better audio, and lots more Ring features” 

We’ve made changes to improve the audio quality, and added new features; these new features are explained below.  All users should pick up this new build as quickly as possible!

1. Who’s Ringing? (Nicknames)

“Ringing” a channel to call everyone has been an unexpectedly popular feature; one of the first questions everyone has when they get “rung” is to ask, “who’s calling?”  So, we’ve added the ability to (optionally) specify a nickname for yourself – a public “handle” that, if you […]
