Use It Long - Cost per day
Track your long-time purchase.
Free · Designed for iPad
Have you ever wondered before buying something: “Is it really worth it in the long run?” Use It Long is an app designed to answer exactly that question.
With this app, you can:
- Track long-term usage of your purchases with an automatically calculated cost per day.
- Compare products: when planning to replace an existing item, you can use the cost per day as a practical reference.
- Multi-currency with historical exchange rates: all conversions are based on the exact rate of the purchase or sale date, giving you precise, time-accurate values.
- Privacy-first: no data collection, no tracking, no transmission. All your information stays securely on your device. The app only connects online to fetch exchange rates — and never your personal data.
From day one, I built Use It Long to meet my own needs. Now I’m sharing it with you, hoping it will help you make smarter, long-term purchase decisions — while keeping your data private
