Description
This app turns your Android phone into a tracker for SlimeVR Server or other supported server applications such as K2VR for IMU-based full body tracking. You can also run owoTrack on some Android-based Wear OS smartwatches.
This does not perform camera-based tracking; it does not use the phone's camera. owoTrack requires your device to have a gyroscope - some phones may lack this hardware.
If you have no other trackers and 1 phone, you can use this to get waist tracking only. For leg tracking, you will need at least 5 phones or some combination of official/DIY SlimeVR trackers, phones/watches (through owoTrack), Joycons (through SlimeVR Wrangler) to get 5 trackers in total. Tracking quality may vary depending on type of devices used.

While this is by no means a full replacement for something like a vive tracker, considering the sensor data available to a phone, it's pretty good + it's open source, so you get a little gold sticker for that.

Works super well, use my phone and smartwatch for chest and hip tracking for my quest 2 in steam vr

Works well with chat but sometimes It's not really accurate

I have no doubt that the app works, but when I put my I. P and the port it gave me (it autofilled the port, so I assume ita the correct one) it said it couldn't connect. I know I put the right I. P, and the headset doesn't tell me what the port is, and no matter what I try it will not connect. This app is unusable.

I have no idea how to use this I need help. This app doesn't work and even once I fill it out it doesn't work. Am I supposed to have the expensive trackers for vr to use this?
★☆☆☆☆Peyton turner· Mar 25, 2023
I tried every option, including hacking into my own network, and I put the correct port number in there, and it still doesn't work. If you don't mind, can you give us a hint at what a port is that would help...
