Does anyone use a therapy app?

I really want to start talking to a therapist but I would love to just do an online chat or even a video chat instead of going to an office. I know there are tons of apps out there but I would love to get recommendations.

If you have used one, what was your experience like ? Did you enjoy it ? How often did you talk to the therapist ? How much did it cost ? Was it worth it ?

Thank you for answering.
