We're working on perfecting the iOS and Android apps first. After that it's hard to say, but we are considering a mobile friendly web-app that'll allow you to use CAM on any phone or computer (so long as it's installed and running on the linked computer you'd like to monitor)
Yes, unfortunately the approval process on the iOS store takes a bit of time. But the app is 100% ready and will be available for download as soon as it clears the App Store processes. In the meantime, the desktop app is available now for free. :)
