They are model estimates, not appraisals. Curves come from typical second-hand behaviour per category, with specific curves for well-known models. If a number looks wrong, open the item and tap Calibrate — enter what it would actually sell for and the curve is refitted around that point while keeping the category's shape.
它们是模型估算，不是专业评估。曲线基于各品类在二手市场的典型表现，知名型号还有各自的单品曲线。如果哪个数字看着不对，打开那件物品点「校准」——填入它实际能卖多少，曲线会围绕这个点重新拟合，同时保留品类原有的形状。
Yes — pick the currency next to the price. The amount is locked into your main currency at the rate for the month you bought it, because what you actually spent is a historical fact and shouldn't drift. The item's current value follows today's rate instead. Main currency lives in Settings.
可以——在价格旁边选货币即可。这笔金额按你买入那个月份的汇率锁定到主货币，因为「当时花了多少」是历史事实，不该随汇率漂移。而这件物品的当前价值走的是今天的汇率。主货币在「设置」里改。
By category — digital, home, collectible, mobility, apparel — each group showing its own subtotal, sorted so the group holding the most value comes first. Within a group, items are sorted by current value. Clothing and shoes headline a per-day cost instead of a residual value, because the residual on a T-shirt is a meaningless number.
按大类分区——数码影像、家居家电、收藏保值、出行运动、衣着——每组带自己的小计，价值最高的组排在最前面。组内按当前价值排序。衣物和鞋履的主指标是日均成本而不是剩余价值，因为一件 T 恤的「残值」是个没有意义的数字。
The bundled catalogue covers common electronics, cameras, lenses and consoles. Anything unknown still works — it falls back to the category curve and you can calibrate it. Send the model name over and it gets added.
内置目录覆盖常见的数码、相机、镜头和游戏机。没收录的照样能用——会回落到品类曲线，也可以自己校准。把型号名发过来就能加进去。
They exist so the first screen isn't empty. The moment you record something of your own they all disappear on their own — or clear them straight away from Settings.
它们的存在只是为了让第一屏不至于是空的。记录第一件属于你的物品后，示例会自动清除；也可在「设置」中直接清除。
Trove follows your system language. To set a different one just for this app, use iOS Settings → Trove → Language, or the shortcut inside the app's own Settings screen.
长物跟随系统语言。想单独给这个 app 指定语言，去 iOS 的「设置 → 长物 → 语言」，或者用 app 设置页里的快捷入口。
Bugs, wrong launch prices, valuations that feel off, or a model you'd like added — all welcome.
Bug、发售价写错了、估值感觉不对、想加某个型号——都欢迎。
