From Eddy Wong:
Have you thought about how many electronic products and home appliances' warranty expired or going to expire? When the products have problem, are you busy to find the serial number, hotline number, etc? Warranty Count helps you manage all your purchased item's information. It tells you how many days left before expiration. All hotline requires information being ready for you to answer. The most interesting part is that it calculates how much it costs of this product everyday uses. The longer you use the product, the cheaper it costs per day, the more value you get from that product.
