The Speed Shopper app is a live app that already has global users.  It pays cryptocurrency to users who add aisle numbers for items that are on their shopping list.  All you have to do is download the app, make a shopping list and when you go shopping add the aisle numbers of the items that you are shopping for and the app will send you crypto.  You can use the SSTX crypto to purchase items in the in app marketplace that only accepts SSTX.  Save them up!  The current value of our cryptocurrency is $0.25/SSTX.  We set the value of our own currency because we accept it for advertising and our merchants accept it for their products.  We don't do airdrops so everyone who has them has earned them or paid for them!
