The counter in a browser
Install counter.gemmetto.com as an app on an iPad’s Home Screen, and what to keep in mind.
The counter also runs in a browser at counter.gemmetto.com. Open it in Safari, then use Add to Home Screen. From then on open it only from its icon.
The counter keeps its data on the iPad. Never delete the icon and never clear Safari’s website data: either one erases sales that were not sent yet.
Updates install by themselves when the counter locks between customers. Read The counter as a home-screen app before the first day.
