Elebon

A change calculator with a sales counter for club events, bake sales, flea markets and school fairs.
Add your products, tap them, enter the coins and notes you receive, read off the change. No mental arithmetic, no scrap paper, no sign-up. Elebon runs on iPhone and iPad, works fully offline and keeps count of what you sold along the way.
Revenue and number of sales at the top, below that the breakdown by day, by person and by product. Tapping a day shows what went over the counter that day. Reset clears the sales for the next event; the products stay.
Share a section with helpers via iCloud, everyone sells on their own iPhone.
All sales end up in one shared statistic, broken down by person. Helpers are invited with a link sent by message or mail; whoever opens it gets the section with its products on their device. Sharing can be stopped at any time. All devices need a signed-in Apple ID.
As many sections as you like, each with its own products, its own statistics and its own sharing. The active section is switched in Settings; checkout and statistics always refer to it.
Elebon has no user account and no server run by the provider. Nothing is collected, nothing is analysed, there is no advertising, no analytics and no in-app purchase. Everything lives on your device and, if you turn on iCloud, in your personal iCloud. Details in the privacy policy.
