Yes, that's a good idea. but I don't think they are going to make, however they can sell it as a separate license and make a good money out of it

Never though about that, you certainly have a point... I can only say.. the app does not steal your hash and api key. Making it open source would not help either, i could upload another version as the "open" one.
I think this is the closest thing to a ios solution, i saw your app and it is exactly what i need just to see if a vm is on and memory usage, i see that you haven't update your app in a while or an update to ios8 and iphone 6... i will buy it but i want to know if your app is still under development or is already abandoned..
