Housekeeping release — nothing changes about your rooms or your sounds. This update adds the measurement that tells us which ads actually bring people to Calmo, so we can spend less on advertising and more on making new rooms and sounds. On iOS you'll see a one-time prompt asking whether to allow this. Saying no changes nothing about what you hear — every room, every object and the sleep timer work exactly the same either way. Calmo still has no ads inside the app, plays in the background, works offline, and needs no account to start.
