Really cool project. I have some comments tho.

I don't quite understand what Connect is. Is it a cloud IDE or is it an add-on to sync your projects across existing clients on Mac or iOS. I think this wording confused me the most on the OSX client: "$9.99 + 6 month subscription* of Texpad Connect". I'd package it as: if you buy OSX client, you get 50% off from Connect for the next 6 months. Or even better, just give 3 month Connect for free with each license.

Also, I don't understand why you'd have to buy Mac and iOS licenses separately. Wouldn't it be nicer to use a single license across all of your devices?
