Is the iPad version a separate purchase?
No. It is one universal build on the App Store, so installing on iPhone installs on iPad too. A Pro license code covers three devices at once across any mix of iOS, Android, macOS, Windows and Linux.
Do I need a hardware keyboard?
No, but it is the point of the iPad build. Without one you get the mobile keyboard toolbar — customizable keys, chords and macros, with the control sequences encoded as data rather than hard-coded. With one, modifiers and function keys reach the remote shell directly.
What is the difference between the iPad and the desktop builds?
Almost nothing at the feature level — the same protocols, renderer, SFTP, workspaces and vault. The iPad keeps the two mobile-only capabilities the desktop builds lack, push alerts and camera QR pairing, and like a Mac with Touch ID it unlocks with biometrics.
Can I edit files on a server from an iPad?
Yes. Workspaces give you a tabbed code editor over SFTP with syntax highlighting, find/replace and a diff viewer. Saves are atomic — a temp file renamed over the target — and PocketCmd checks whether the remote changed while you were editing before it overwrites anything.
