I use it for lots of things. I’m not a coder, so I can’t make my own apps from scratch. With Tasker I can make my own apps. I’ve made tons of them.

I still have a Reddit account because there are some core subs that haven’t migrated, but I don’t have to official app installed. I use Tasker to check Reddit and notify me of posts.

My memory is horrible and my schedule is varied every day, so I can’t set alarms for certain times. I made an app where I can say something to my watch and it will remind me depending on my location. For example, I can remind myself to get paper towels on my way home from work. When I leave work, it will send a reminder to my watch.

I use it for call screening. I only let calls from my contacts ring. It sends all other calls to voicemail.

I use it to run scripts in Termux.

I have a routine that will tell me why an app was closed.

I have it POST things to the timeline on my watch with JSON.

I have it reassign functions to my phone’s buttons. I made an app that turns on the flashlight when I shake the phone.

I have it put the battery level of my Bluetooth devices in my notification bar and on my watchface.

I have it gather weather and notify me conditions and severe weather alerts.

I could go on and on, but you get the idea. You can do just about anything with it.
