Unfortunately we can't share the timeframe for our future updates or what it will contain.
Feel free to like/follow us on facebook and twitter for the most up to date information. We often share sneak peek of what we are working on and also announce the content of a new update when we submit it to Apple.
Once we submit an update, it takes Apple 10 to 12 days to review it before we can publish it.
We try our best to roll out updates as frequently as possible and so far we managed to release new feature/content every month or 2.
