Yes. Coherence is free to download on iPhone and Android.

Only during live sessions that are recorded. Before recording starts, Coherence shows a recording notice, and recording begins only after you tap **Agree and start**. Scans, breathing exercises and other activities don't save video. Video is never sent to third-party AI providers.
