EaseUS MobiMover is a free tool for transferring data between your iPhone and computer, iPhone and iPhone. You can use it to transfer or manage files for free. The free video and audio downloader that is offered with the software is much more comprehensive than you would expect for a free tool.
It is an excellent alternative to iTunes for transferring files between devices. With iTunes you can occasionally lose files because it syncs data, rather than transferring it. For example you have removed a music album from your PC, but you want it to remain on your iPhone you could lose it. MobiMover on the other hand allows you to transfer data with relative ease. Its clean interface and fast installation certainly helps MobiMover stand out.
Yes, this software is free. A pro version is also available here for 1-month at $29.95, 1-year for $39.95 or a lifetime for $79.95.
If you are interested in using this product regularly then purchasing a licence may be a good idea as you can do unlimited file transfers, and you will have access to 24/7 technical support if needed.
