It is compatible with ANY smartphone. I have it attached to my Samsung Note 10 plus for now. I cannot believe the quality myself. Just purchased a mini tripod from Amazon and waiting for it to arrive which should give me a bit better results hopefully π€·ββοΈ. Below are a couple photos of the attachment. I chose this one based on the reviews and the fact that it is a 100mm DSLR equivalent which allows you to back away from the watch a bit to let in more light. It is super easy to use and takes 10 - 15 secs to installπ
