For the first 10 minutes of a using a program on the pink app, the healy is working out which frequencies your body needs the most. The frequency will change every 10 seconds. The progress percentage shows how much the frequency has been absorbed/assimilated. It ranges from -99% to +99%. -99 means your body really needs that frequency and +99 means it has just about assimilated that frequency. When it has reached 100% that frequency will disappear from the cycle. Sometimes the program will finish early because your body has assimilated all it needed.
