What kind of decisions does this work on?
The ones with a number in them and a date attached. Quitting, buying, moving, hiring, taking the offer, ending the contract. It works badly on "should I be happier", because there is nothing to check.
Is it really free to try?
Three complete Grills, no account and no card. The paywall arrives after the third one, which is late enough that you already know whether it is worth anything.
Does it record my voice?
No. Speech becomes text on your iPhone and the audio is never uploaded. There is nothing to delete later because there was never a recording to keep.
Is this just a chatbot with a prompt?
It is one character with one job and a written output he has to produce. He asks one question at a time, holds what you said earlier against what you say next, and ends with a verdict he has to defend. A chat window will agree with you if you push; this is built not to.
Which languages does he speak?
Nine: English, German, Spanish, Portuguese, French, Simplified and Traditional Chinese, Korean and Japanese. He is written in each of them rather than translated into them, so the insults land in the right language.
Is there an Android version?
Not today. iPhone only, iOS 26 or newer.
