Panic Inc., the team behind a bunch of excellent iOS/Mac apps (like Coda, Transmit, and Prompt), are about to retire one of their products. Sometime “very soon”, Transmit for iOS will be taken off the App Store.

Transmit is Panic’s take on a modern file manager for FTP/SFTP/Amazon S3 servers. After over a decade as a Mac app, Panic rebuilt Transmit for iOS and released it around the end of 2014.
