Ratings and reviews

This is the only app for Android that I could get to use public keys, and it works seamlessly. It took me a while to figure out how to mount a directory that would allow me to view uploaded files on the phone, but the developer pointed the way. I like the security of having the phone be the sftp server, rather than the client, as in some other apps that I tried.

This is a great alternative to mtp-based file ops. I used this to move a large set of files from my phone to a harddrive via a linux desktop. Before I used jmtpfs to interface with phone storage, but this was unbearably slow. This app worked out of the box and managed to move the files in a fraction of the time and wirelessly! The interface too is very clean and helpful. 5 out of 5 stars, great job!

I like the simplicity. I like that it accesses root, as it means can access SD card and internal storage without needing to choose between one or the other each time, as many other apps require. Update: initially, I had no write access to SD card; developer introduced an additional 'Mount' feature that overcame this limitation. Impressive that can simultaneously open internal and external storage with write access to and between both. Other apps don't seem to allow this. Thank you so much!
