Tap the link, install TestFlight if it asks you to, then tap Install for Hump. Once it's on your home screen, you can just open it normally.
All users are either AI profiles to interact with, or friends of mine you can talk to, match with, and chat about the app, me, or your experience.
Feel free to text me any feedback, or use the onboard feedback as a tester.
Happy Humping.
Here's the web app — you can save it to your home screen just like a real app.
