OK, if you have an IR blaster on your device, specifically the S4, you'd do well to grab this remote app. I've used it when Emma falls asleep on me and I can't reach the real remote without disturbing her.
Now I buy apps I use regularly to support those devs that work hard. This app has been updated quite a bit, he's on top of things. However the purchased features crash the app on my device.
I emailed for a refund, and surprisingly I received it quickly. I was also surprised he emailed asking for details as to the crashes.
I probably email devs a bit more than the average guy, and I'll tell you that quick responses are rare. Even more rare when a refund is involved. (Remembering the tool that demanded a 5 star review before refunding)
Guys, pick this up. Better yet spend $1.99 in app. I believe he will fix the crashes, and keep the app updated. Always support good/great devs.
