Pukuku takes a few things your phone notices anyway, weighs them over the day and draws your day from them. If they leave something open, it asks you.
A small Bluetooth beacon on your desk. Your phone notices when you sit down and when you step away, the thrifty way, without scanning over and over.
Decides the start, every break and the endYour phone tells Pukuku when you arrive at or leave one of your places. Pukuku keeps the fact, "arrived at work", never a trail of where you've been.
Decides the start and end at work, and whether you're homeIt pins down the moment you really arrived or left, and tells a drive to a customer apart from a break. Phones sometimes go quiet for a while, so this clue never decides on its own.
Sharpens when you came and went, and spots travelExact the moment you tap. Give the same answer five times, and Pukuku stops asking: it fills the answer in for you and marks it as assumed.
Always wins over anything Pukuku worked outYou spend your evenings at home too, and leaving the office might just mean a meeting across the road. So no single clue is ever the answer. Pukuku looks at what came before and after, and how long it lasted.
You never switch modes. A morning at your desk at home and an afternoon at the office are simply two parts of one day, and each is read the way that place should be.
Pukuku only suggests a time when it has a reason: a habit it learned or something it noticed. Otherwise it lets you pick. You can undo every answer, and each one teaches Pukuku, so the same question comes up less and less.
Pukuku learns your habits from your own answers and fixes, right on your phone, and uses them to read your next days.
These are the goals we build and test Pukuku against in the pilot. We'll only call them results once the pilot shows them in ordinary weeks.
In the pilot, these rules meet real weeks.
