Why I built it
I watched the problem from behind the bar. Nobody asked me to build this. Front-of-house pay is split across a wage, cash tips, card tips that the machine holds until payout day, and tip-out to the kitchen. Most people end the month guessing.
What it does
Log a shift on the way home: when you started, when you finished, cash tips, card tips and tip-out, tapped in like a till. It runs on your pay cycle rather than the calendar, pays Sundays and public holidays at the right rate, keeps a 2am finish on the right night, and shows what you really earn an hour.
Privacy by design
There's no account and no server. Every figure lives on the phone, so there is nothing to leak and nobody to ask for it, including the employer.
