Okay, call me Thrifty, but $9.99 sounds like a lot for an app. I know it sounds cheap, but $6.99 or $7.99 and I would have jumped. Maybe I resist because $6.99 is the most I've spent on a mobile app. I usually buy the Pro version of an app to support the Devs, but I got sticker shock when I looked at this price.
Don't get me wrong, I love Blue Iris. Just my opinion. I have purchased 2 full licenses for Blue Iris, but I use tinyCam Monitor Pro for mobile viewing and it serves me well.
