I'm interested in buying your software, but I change smartphone every few months, let's say, as an average, about every 3 months with another sample of the same model, and about every year with a new model.
Of course it happens because I work with them, I'm not so rich to really buy a new one 4 times/year ;-).

Here is my problem: I'm interested in using your software on just one device at once, I've read that your license allows installation of 3 devices, but the limit applies only to concurrent installations or even on subsequent installations?
If I have it installed on just one Android device each time, am I allowed to change that device as much as I need it ?

Thanks in advance for your help.
