I recently bought a Samsung Note 3 which has built-in IR. I installed the latest TouchSquid version, GR Pro, on it and could not be more pleased. TouchSquid offers almost as much customization as the most advanced Pronto. The Note 3 has a powerful IR blaster, much better than earlier Samsung devices like the Galaxy Tab 2. By the way, I paid $20 for the Note 3 from Amazon.

I've tried them all, and TouchSquid GR Pro is the best of the breed by far. It's only weakness is poor documentation, but that will not be a problem for anyone who has ever programmed a Pronto.

It took me about 6 hours to get it all done including making 300 custom buttons for my CD jukebox collection. I recommend TouchSquid without reservation.
