Great for photos over SFTP
I use this app to send photos from my iPad to my home file server using SFTP. It works great - very easy and intuitive to select photos and queue them up for transfer. I like that it allows me to create the SSH key pair elsewhere and import it into the app. That way I dont have to trust the apps key generation to be robust.
The only other app Ive found that can come close to this one for my purposes is Files Connect. This app handily wins because of its much better UI, key importing, and proper support of key passphrases. (Files Connect always saves the passphrase, so that anybody who steals my iPhone will have full access to my files.)
