Give a neighbor an hour — a ride, a visit, an errand. Confirm it together, right there, on one phone. It banks at par, and you get a tamper-evident receipt you can verify anytime.
Bank an hour
Log the hour you gave.

Now hand the phone to your neighbor.
They confirm the hour happened by typing their own email — that’s the second signature.
The rules that keep it honest: one hour is one hour, whatever the task — at par, never cash, never for sale. The bank is for care beyond your own household (family care is tracked, not tokenized). And a negative balance is fine — that’s what neighbors are for.
