Other lottery apps
Are there more apps like this?
Several. Ones that sell and keep the ticket: TuLotero, Laguinda, Búho de la Suerte —which runs pools and emails each participant their receipt— and the official Loterías app. And there are scanners, like Maxiloto or Lotería Cano, which check any official ticket but organise nothing between people. Of the ones that only organise tickets already bought, like this one, there is very little: the usual thing is still a spreadsheet and a WhatsApp group.
