I have an iphone and so it is not possible to transfer data via bluetooth and I cant download songs videos etc from internet as well.xender is the best option for me to transfer the file from any other phone to my phone.i can send a picture or anything from my phone to any other phone as well.big movies can transfer in few minutes via xender so it is very mucj popular among android users as well.in ios you have to open xender to use the xender file while in android files directly comes to your gallery or music.so the concept is excellent.connecting phones is very easy and dont use the internet as well.very nicely designed.they need to improve their video player and song player in ios.rarely it crash and transmission error occur during file transfer.apart from that xender is very usefull and must have for every ios user.
