CastVolume puts volume and mute controls on your Home Screen and Lock Screen with interactive widgets for Chromecast-enabled speakers and TVs, and compatible WiiM receivers. Keep music in your usual app. CastVolume controls the receiver directly, so you can adjust a WiiM even when playback was started with WiiM Home or its remote. It does not start or stream music and is not a universal AirPlay remote. YOUR VOLUME, ONE TAP AWAY • Use interactive widgets for quick volume and mute without opening the app. • Adjust volume and mute in the app. • Use volume controls in Control Center. • Discover receivers on your Wi-Fi, or add a WiiM by IP when needed. MORE ROOMS WITH PREMIUM Pin multiple receivers and choose a different device for each widget. Save volume presets, use the dedicated Preset Volumes widget, choose your volume step and customize themes. A single one-time Premium purchase covers both Chromecast and WiiM. No subscription. Basic control and one pinned widget device are free. No ads or account required. Connect your iPhone and receiver to the same local Wi-Fi and allow Local Network access. WiiM volume control requires variable volume output; turn off Fixed Volume Output in WiiM Home if enabled. A locked iPhone may require unlocking before a widget command runs.
