About this app
From “expensive” to “I want it”—a simple calculator app that shifts your shopping perspective. Those coveted shoes, gadgets you want to use for years, or that outfit you're splurging on. Items that seem expensive at first glance actually have a much lower daily cost when you factor in their long lifespan. Simply enter the “price” and “expected years of use,” and this app instantly calculates the true daily cost. It helps turn your hesitation—“This is a bit pricey...”—into confidence—“This is a smart investment!” [Easy to Use] Enter the name and price of the item you want. Set the intended period of use (years, months, weeks). It displays the "effective price" per day! [Useful in These Situations!] When you're unsure if a 30,000 yen pair of sneakers is too expensive. When you want to convince yourself that a 100,000 yen home appliance is affordable if you use it for 5 years. When you need material to negotiate with your partner to get permission to buy something.
