So I am looking for an app which will allow me to track things. Examples:

- few days ago I filled up my dog's storage of food, how long it will last?
- today I replaced battery in few IoT things, how long they will last?

and so on.
Notes work, but I... need manually calculate things.

Don't tell me I will need to write this app.
Because I will.
But I don't want to.
Because I don't know how... yet.

@sashk sounds like a great app idea

New thing to track? Mark a start date "I did new thing!" and optionally fill out an estimated date you'll need to do it again

Then either you get the reminder and you do the thing and hit "I did the thing"

Or on some other day you hit "I did the thing"

And then based on how many times you did the thing vs how long between times, it finds an average for when you'll likely next need to do the thing

@sashk Maybe with a configurable "warn me X days / y% of time remaining before I likely need to do the thing
@sashk Call it "Occasion Ally" πŸ˜†
@mikeymikey I really hope someone though about this already and all I’ll have to do is to find it. :)
@sashk, I’m using self-hosted Grocy for similar purpose, but not sure if it will work for you. It has something for batteries though, and I think there is a way to set custom expiration dates for items and create shopping lists based on that.
@danilkomarov Thanks. Brief look and it seems like even more than I was looking for. Will look in depth during the weekend.
