Can I transfer my zedge ringtone app from my iPhone 4s to my new SE.?

[iMore Question]

I have d/l the ringtone Zedge app to my windows laptop and tone synced it to my iPhone 4s. I am picking up my new iPhone SE and wondered if this app could be transferred onto the new phone fr my laptop? Or is there another process that I must use.? If so where would I find the instructions on how to do this and would this mean that I have to uninstall the program off my Windows laptop.?
All comments greatly appreciated. Thx
