Happi is a very good app, i hate my job and am always tired after work so I like to play with anxiety tools on my phone. I have a lot of such apps don't ask why! But i just do, but mental stimulation and ASMR are the main reasons for me to use slime. Again there are no ads in this app so I can recommend it to you guys to use and play with.
It has slime simulator, fluid simulator, and various other tool that promote mental peace and harmony. I would strongly suggest you to try this app. It has no ads and you can try it out for free. Only if you're interested you can subscribe to it. It's overall a pretty well thought out app and it does work. Both me and my brother play this app for hours and they keep adding new slimes every day
