CheckIn IS great, I use it daily since "when are you coming home" is otherwise something I'd be asked.
Infuriatingly though it appears to have zero data saving of preferences. I have to manually type my home address and select driving mode, every single time. It's like 30 taps when it could be 1. I sent them a Radar. I'm sure it will never be looked at.
Just now, I realized I can just vibecode my own version.
