The ChatGPT mobile app in voice conversation mode works quite well for language practice with one important call-out: you have to give it a topic at the beginning otherwise it won't be able to drive the conversation forward and will stick to banal pleasantries. So what I usually do is pick a random blurb in the news and paste the entire thing along with the Reuters link at the beginning and inform chatgpt that we'll be carrying on language practice specifically over that topic of discussion. I've used this to carry an hour long foreign language practice in Spanish while walking my dog without even needing to look at my phone.
