Finishing all content quickly with nothing new afterward is a dealbreaker for me too. Some apps give you a full journey upfront but no ongoing materials. Before committing to any 90 day subscription, I needed to know if the content runs out. What helped was reading honest user experiences about exactly this problem. One person admitted they finished the journey pretty quickly and found no new lessons after that.
