I have a very similar situation: a cat with a severe kidney disability, meds 5 times a day with at least 2h between each. We’ve been using a whiteboard but I am currently setting a smarter solution. My WIP setup is a raspberry pi with a static IP on my local network and a FastAPI app. This way I can also do a household to-do lists (did anybody watered plants recently?) and add connection to local smart lights (effects if meds could not be given with 2h interval before our usual go-to-bed time), etc.
It would only work for us since it is a household only solution. Our cats do not travel anywhere and I do not currently need to check for these todos when not at home. It may be different for you. Good luck OP, hope you will find something that suits you.
Very natural look, to be honest I am quite impressed that it isn’t a industry standard right now and also that I have never thought that it was missing in games. I’d only tweak one thing: for a most natural look all surfaces shouldn’t be “touchable” at all times. We usually touch barriers (such as at 0:25), wall corners around which we walk, some vertical bars, moving objects (doors, office chairs), etc. With these restrictions it would look absolutely stunning in a video game. Remove this restriction with some conditions (character is drunk, walking at height, instable for some reason, etc.) and it would really be a piece of animation I would like to be modded into every single game I own.
