Mine is an iOS app, but I've lost access to several through the years, I assume due to geo-location stuff and the fact these apps can be used for gambling. The current one I am using is called Rafflenumbers, spelled like that without a space, it's one of the lower ranked raffle apps, but it performs the task I need, basically providing a 1 to XXXXX ticket count, and then a random draw.
It's pretty barebones, and there's also a dice roller within the app, but that's it. There are plenty of raffle apps with lists and more data options, even assigning names, etc., but of course you'll spend a lot more time setting it up each time as well.
