I often need to upload files from my iPhone or iPad directly to the web server. I have been using iTransfer (ad-supported version) for quite some times. I purchased iTransfer Pro considering how much I have been using the free/ad-supported version; the $3.99 price tag is worth it. iTransfer Pro is both iPhone and iPad optimized.
iTransfer Pro supports:
- FTP/FTPS/SFTP
- Network Drives
- Dropbox
- Box
- SkyDrive
- GoogleDrive
