Zhizu

Zhizu is a minimalist tracker that helps you appreciate what you already own. Instead of nudging you to buy more, Zhizu helps you make the most of what you have. Record each item's purchase price and how long you've used it, and Zhizu automatically calculates its daily cost — the longer you use something, the cheaper each day becomes. It's a gentle, honest way to value your belongings and think twice before the next impulse buy. Why Zhizu: • Completely free — no item limit, no in‑app purchases, no subscriptions, no ads. • Daily cost — see the real per‑day cost of every item; value grows the more you use it. • Asset overview — In use / Retired / Favorites, all at a glance. • Statistics — charts of your assets by category and value for a clear picture. • Wishlist — capture things you want to buy and spend more intentionally. • Custom themes — a soft lavender palette built in, plus your own custom gradients and Light / Dark / System appearance. • Privacy first — all data is stored locally on your device (SwiftData). No personal data collected, no third‑party tracking, no account required. Own less, enjoy more.
