I find Airdroid to be an aggressively and persistently intrusive app, demanding of your most personal and direct information that locks you out if you will not give it to them and makes getting back in as complicated and difficult as they can possibly manage to make it. I deleted it off my phone in disgust, and it saddens me to have to do so as there is no other way to get photos off my phone onto my computer, which they seem to know and use to their advantage to intrude into my personal life. I hate them for that!
I used it a lot when I had an android. It was great for writing texts on my laptop rather than typing them on my phone. The only problem was it had an occasional glitch. Aside from that awesome and highly recommended!
