Any suggestions for journaling apps?

I'm trying to find a journaling app on Android that doesn't prompt me to upgrade to premium every two seconds. My therapist suggested journaling might help, but with my carpal tunnel it's hard to journal with pen and paper. But so many of the apps want to suggest premium all the time, and it's frustrating.

I'm really looking for an app that also has prompts. I struggle with figuring out what to write, so having prompts really help.

Thanks in advance!
