WhenSpesa advises you at what precise moment of the day you can go to your local supermarket for shopping.

You enter your postcode, the chosen day, the time slot (morning or afternoon) and your favorite supermarket among those offered within 2500 meters and WhenSpending offers you three 10-minute slots within which to present yourself at the shop to make your purchases. The timetable will certainly be the least popular among all the owners of the app who have decided to go shopping on the same day and in the same store.
