Saving a profile to be view and like later is not a functionality we have today. We have written this feature for a potential feature build for the future.
For now, we encourage you to go ahead and like the profile you are interested in or may even the slightest interest in. You never know who someone is until you chat with them. The goal is to connect and get to know people, so we actually discourage people from waiting and analyzing profiles too much before you actually connect and get to know each other. Hope that relieves some pressure off of if you should like a profile or not -- go ahead and do it! There is nothing to lose when there is a Jesus story on the other side! May God's boldness and peace be with you!
