Local (Push) notifications

[jiaaro]

Along the lines of:

• It's about time to go grocery shopping again (it's been 6 days). Add your regular items (yogurt, coffee, chicken, milk, eggs) to the list?
  [yes] [no] [do it myself]

Idea for when to schedule a notification:

Use a naive baesian classifier to assign a probability to each day in the future, schedule a notification once the probability reaches a certain threshold.

Inputs are:

• time since last N (5?) items were checked off
• day of the week (monday/tues/etc)
• time of day

Basically some days are more likely (saturday for instance) so we want to weight on that.

And we want to approximate the average delay between grocery store trips.

min and max time will be needed (shouldn't be more often than every day, and anything over 2 or 3 weeks is obviously too long)

On the other hand, we could also just ask the user how long to wait before firing a reminder.

---

Or we could use location and try to guess when they're at the grocery store

Things that might justify a reminder:

• time to add something to your list
• hey you're at the grocery store, don't forget to get the stuff on your list
