Transmit

Since its introduction well over a decade ago, Transmit has served as our go-to FTP solution on the Mac. Now, finally, it's available for our iPhones and iPads too. Transmit iOS brings the rock-solid transfer engine of the desktop version to your pocket, letting you open, edit, and save files over FTP, SFTP, WebDAV, and Amazon S3. Thanks to iOS 8's App Extensions, you can upload files from any app that supports Share sheets, and thanks to the new Document Picker, you can also open files remotely from your servers without even leaving the app you're in. Add in Touch ID authentication for added security, and you've got the best iOS file transfer client money can buy.
