We introduced our iPhone app in December 2010; a virtually identical Android app was released in late April 2011. If you are looking for Hearts of Space on-the-go, follow these links and download the app of your choice for just 99 cents.
iPhone App Store Android Market
Both these apps currently have a reduced set of features when compared to our main web site with its custom Flash player. To be specific, after free registration you can play
- a selection of free introductory content
- the current week's program (as often as you like)
Subscribers who purchase our "Radio Channel + This Week's Show" combo plan ($5 to $7 per month, depending on term and billing options) OR our "All Archive Access" plan ($10 to $13 per month, depending), also get unlimited access to our full time radio stream — the "All Archive Channel" — in both the mobile apps and online in all major web browsers. If you turn off the program voiceovers, this service is ideal for uninterrupted background music.
OUR NEXT UPGRADE
We have begun work on the next upgrade to both our mobile apps and our main web service. The enhancements include seven new full time "virtual radio channels" in addition to our current "All Archive Channel." Here's the list of channels:
ALL ARCHIVE MIX (aka "All Archive Channel" — same as the current "Radio Channel")
ELECTRONIC SPACE
AMBIENT/DOWNTEMPO
CONTEMPORARY INSTRUMENTAL
ORCHESTRAL/CHAMBER/CHORAL
CLASSIC HOS MIX
WORLD FUSION MIX
CELTIC SPACE
Per user request, the next version of our mobile apps will also show and play MY PLAYLISTS that you've created on the web site.
One enhancement already being enjoyed by mobile users is that HOS programs in the ALL ARCHIVE MIX channel always start from the beginning — rather than being joined in progress, traditional radio-style. We will add this feature to our main web service Flash player in the next update.
LOOKING FORWARD
Our development roadmap for the near future is committed to supporting all features and services on both the web and mobile platforms. This means that whether you use the HOS music service on your desktop, laptop, tablet or mobile phone, the same content and features will be available to you — depending, of course, on the service level you choose. However, we won't get there until the revision after next.
Look for our upgraded mobile apps and upgraded web service with 8 full-time channels this fall. Our "full featured" mobile apps will follow, hopefully in the first quarter of 2012.

I've been checking my App Store updates page frequently, anticipating the Version 2 iPhone app update; so I was elated to see it pop up there tonight! I'm loving it already, with my playlists now available, and the variety of channels is great, too. This will probably be one of my most-used apps now! Thank you so much -- well worth the wait.
