Using something like this is super useful when dating new people, and for someone (like me) who have several partners and wants to make sure that they are being safe and remembering which experiences were great and which were — less good. The features in HookBook are incredibly useful, they allow you to import partners from your contacts in your phone, they have a dedicated tab when adding a new connection for protection, tags for the activities you and your partner did together, a rating system, and a ton more. The interface is really simple and easy to navigate. I definitely recommend this app.
