Hello friends!

The title says it all. I'm searching for a good CBT app that will help me catalogue, categorize, and manage my anxiety symptoms as they arise on the go. Ideally I'm looking for an app that uses the different kinds of "distorted thinking" (mind reading, catastrophizing, all or nothing, etc.) 

I'm on Android, and I'd prefer something that's either free, or comes with a one-time payment rather than an ongoing subscription. 

Thank you all in advance for any input!
