Hi, For an app that is device dependent (communication through bluetooth and network) for proprietary device in specialized applications, is allowed the use of license key on app store without in app purchases? The app is useless for users without the hardware Thanks
What do you need a license key for at all? If the app is useless without the hardware, just give it away, no license required.
It is a bit of a hassle getting through app review for an app which communicates with specialized hardware - Apple may want the hardware to carry out their review, or they will make some other arrangement.
