Unfortunately, it is not technologically possible to link separate apps so they play in succession. Also, we don't recommend listening to more than one topic in a sitting so that your subconscious mind has time to process the suggestions. It would be better to listen to one topic in the morning and another in the evening, for example, or on alternating days.
However, the audio from all our apps is also available in MP3 format. You could download those MP3s and create a custom playlist that plays multiple topics in succession. You can purchase the MP3s at:
