Quick answer: Open Couchius on the same Wi‑Fi as your Roku, tap it in the list, and the remote is ready. There’s no code. Turn the dial for volume, use the d‑pad, type searches from your iPhone keyboard and open channels from the apps list.
What you get on a Roku
- D‑pad, OK, Back, Home and the playback keys, with a vibration you feel on every press.
- Volume and mute on Roku TVs, on a turned dial that clicks once per step.
- Keyboard: letters appear in the Roku’s search box as you type.
- Apps: every channel installed on the Roku, one tap to open.
- Turn on a Roku TV that has Fast TV Start enabled (Settings › System › Power).
- Switch inputs on a Roku TV: press Home and choose the HDMI or Live TV tile (how to change input without the remote).
When a Roku blocks phone apps
Some Roku software limits which apps on your network may control it. If Couchius finds your Roku but nothing happens, change Control by mobile apps › Network access to Permissive. The full walk-through is in using your iPhone as a Roku remote.
