How Long

Ever wondered how much dog food you buy every month, or how long a tube of toothpaste actually lasts? How Long helps you track everyday purchases, from pet food to skincare, so you always know when to restock and how much you're really spending over time. WHAT YOU CAN DO • Log a purchase with a name, category, price, and date in seconds • See at a glance how many days it's been since you bought something • A simple color-coded bar shows if an item is fresh, running low, or likely already gone, based on how long it lasted last time • Get the estimated cost per month or per day for anything you buy regularly • Browse your purchase history, and undo a mistake in one tap • Get a monthly summary: total spent, purchases by category, average duration by category, and how it compares to last month • Pick a custom icon for each category so your list is easy to scan • Available in English and Portuguese (Brazil), with local currency formatting How Long is built by a solo independent developer. Feedback is always welcome.
