Two thousand people used Groat between March and September. With their permission we looked at the shape of their months, not the amounts.
The first week
Spending in the seven days after payday ran 38 per cent above the daily average. The last seven days ran 31 per cent below it.
What changed
Three things moved once people had kept a daily number for two months.
The first-week bulge fell to 12 per cent
Overdraft days fell by more than half
The median person opened the app once a day, for four seconds
None of this is a study. It is what we saw, and it is why the number resets every morning.
