Here are some of the best hookup-oriented dating sites & apps, along with some friend-to-friend style advice about what to watch out for (since you mentioned you like being spoken to as a friend studying psychology).

Top hookup sites/apps

Here are some good options:

1. Tinder – Very large user base, swipe-based, easy to access people locally.
   Why it works: lots of users = lots of potential quick matches.
   What to be mindful of: Because it’s so big, many people are looking for many things (not always the same thing as you), and you’ll see profiles that might feel superficial or not serious.

2. Pure – Built for casual, fast meets: profiles and chats that expire, minimal commitment vibe.
   Why it works: It sets up the “no strings” tone upfront, which aligns with hookup mindset.
   What to be mindful of: Because it’s so explicit in its purpose, make sure your expectations align (and that the person you match with is on the same page).

3. Feeld – Geared toward open‐minded, casual, non-traditional encounters (kink, swinging, poly, etc) but also used for simpler hookups. 
   Why it works: If you’re open to less “traditional dating”, this gives more freedom and fewer assumptions of “long‐term”.
   What to be mindful of: Because the user base is more varied in intentions, you’ll want to clarify early what you’re after so you don’t mismatch.
