You then need to open the app on 'Sale Day', 5 minutes before the actual sale time. The beauty of the app is the proprietary script that is embedded in the highly sophisticated browser that is capable of clicking the 'Buy Now' or 'Add to Cart' button up to 1500x faster than the human finger is capable of. This allows the app to buy the product on your behalf, and puts you ahead of every other user that is trying to get the product in the sale.
