The best ideas arrive with your hands full. Drift on the Apple Watch is one button that records, on the wrist, without unlocking anything, without your phone in the room.
A watch is not a small phone. You have one hand, two seconds and no attention, so anything that asks you to choose has already failed. Drift on the Watch does exactly one thing, which is the only honest thing to put on a wrist.
Running, cooking, driving, carrying a child. These are the moments ideas actually arrive, and they are exactly the moments a phone is unreachable. This is the difference between a system that catches most of them and one that catches all of them.
