Supported Yes — Remote Pro controls it
The Fire TV Cube runs Fire TV, which is a platform Remote Pro speaks natively — over your own WiFi, no extra hardware.
The Fire TV Cube pairs exactly like a Fire TV Stick — 4-digit PIN, no account. The Cube does have its own infrared emitter for your TV’s volume, but that is driven by the Cube’s hardware and Alexa, not by anything an app can send it.
Setup
Your Fire TV Cube and your iPhone need to be on the same WiFi network. That is the only requirement — no dongle, no hub, no infrared.
Put the iPhone and the Fire TV on the same WiFi network.
Open Remote Pro and tap Scan. The Fire TV appears by its device name.
Tap it. A 4-digit PIN appears on the TV screen — type it into Remote Pro. No Amazon account, no sign-in, no profile picking, no developer options and no ADB.
Paired. Navigation, OK, back, home, menu, playback, sleep, and iPhone-keyboard typing into Fire TV search and password fields — the single best reason to use a phone as a Fire TV remote.

The honest part
Volume and channel do not work over the network on Fire TV — not in Remote Pro, and not in any other app. Amazon’s protocol simply has no volume command; the physical remote sends volume over infrared or HDMI-CEC to the television instead. Apps that show volume buttons anyway are failing silently. Remote Pro disables them and says why, and you use the TV’s own volume (or the TV brand’s app) alongside.
Fire TV devices stay network-awake in standby, so Remote Pro can wake one up — useful when the physical remote has vanished entirely.
An iPhone has no infrared blaster, so a television that is only controllable by infrared cannot be controlled by any phone app — ours or anyone else’s. We say that on every page rather than hide it in a review reply.
The official Amazon Fire TV app is free and works well — after you sign into an Amazon account and pick a profile. If you would rather not log in, or it is not your Amazon account, Remote Pro pairs with the device itself.
Remote Pro controls Samsung, Fire TV, Android TV / Google TV and Roku from one app, over your own WiFi. Full D-pad, volume where the platform supports it, and a real iPhone keyboard for search fields.
