久用 LongUse

LongUse helps you understand the daily cost of the things you own. Record a purchase price and date, then watch the cost per day change as you keep using an item. YOUR ITEMS, AT A GLANCE See your total daily cost, total purchase value and time owned. Organize items with built-in or custom categories, search your records, and keep notes. PLAN BEFORE YOU BUY Keep a wishlist and estimate costs after 100 or 365 days of use. When you buy an item, confirm the purchase date to move it into your purchased records. EXPLORE COST OVER TIME View a 100-day forecast for your current items, compare individual curves, and track usage milestones. Forecasts are arithmetic estimates based on continued use, without new purchases. They do not represent resale values or actual savings. USAGE INSIGHTS Offline statistics calculate costs directly on your device. Optional cloud analysis supports a service and API key you configure yourself. Before each request, LongUse asks for confirmation and identifies the destination. Only aggregate item counts, average days owned and daily costs are sent; item names and notes are not sent. The selected service may charge fees and has its own privacy policy. WIDGETS AND REMINDERS Add daily-cost, forecast, milestone and longest-used-item widgets to your Home Screen. Set daily-cost goals; LongUse checks them when you open the app and can notify you when a goal is reached. YOUR RECORDS Use LongUse locally without an app account, or enable private iCloud sync across your Apple devices. No advertising or behavioral tracking SDKs. Edit and delete your records in the app. Available in English, Simplified Chinese, Traditional Chinese and Japanese. IPHONE DUO Version 2.0 adapts the interface to the available screen space on iPhone Duo, while retaining LongUse’s existing features.
