I've got a pile of old iPads that would be nice to resurrect as displays. I downloaded the Mac app but balked and left at the double-digit price. (not to mention the unknown in-app purchase)
I don't really care that most app's are cheap. They're also mostly awful.
I'll pay for good ones. I think we should do away with this attitude that all phone apps must cost next to nothing.
There's no way to know the quality of this app until the money is paid.
I have a Mac. 1K+ is not throwaway money to me. I don't see a way to evaluate it. If there's no way to know if it'll work for me before putting down the money, then forget it.
I grew up poor, so believe me, I can understand watching my pennies. I have to figure if you're on HN, and you've got a pile of old iPads, $19 bucks should not be that bad for what it gives you.
Now when I am on the road I can have two displays too.
Great app!
I have already saved myself time in the few hours I have used it not having to switch screens, or download files to my iPad. It will pay for itself in one day at most.
I downloaded the Mac app clicked the "don't forget to download the iOS app!" link, saw $18.99 - and deleted the download.
(I realise $20 is actually a low price for a piece of software, but I don't _need_ this, and $20 is more than I wanted to spend out of curiosity.)
One other complaint for me - it proudly states "All iPads!" than says "iOS7.0+", which leaves out my still working original iPad which can't upgrade to 7.0... That was kinda frustrating.
I'd happily settle for the old-school 72dpi screen resolution, and I'd happily settle for very slow screen update rates (it'd still be useful to me to have irc/email/slack/notifications sitting next to my monitor at even 2 or 3Hz refresh rates instead of 60+fps... I don't need it for playing fast-twitch first person shooter games...)
The disappointment of reading "All iPads" and thinking "Awesome, that's a great use for my old iPad!", then having them say "Except for you, Ah ha!" underneath was a little galling...
