Pos App

[Sycamore3House]

Does anyone use or know the name of an app that acts as a Point of Sale for an ipad/ or other device that does not have a monthly charge.
There are lots of free apps on the App Store but the ones I have looked at all offer a free trial and then a monthly fee. The apps are usually compatible with other devices apart from ipad.
Just want a basic one that would produce a few reports such as daily sales/invoices etc
TIA
