Tolero 技术支持
读数和实际尺寸差了一点
请把手机放平，正对屏幕垂直俯视，并取下贴膜后再对比。屏幕出厂公差、贴膜厚度和视差都会带来小误差，无法完全消除。Tolero 仅供生活参考，不可用于工业精密测量。
设置里的“当前设备”不对，或读数整体偏大偏小
App 按 iPhone 型号匹配屏幕密度来换算毫米。如果你的机型不在内置表中，会按屏幕像素密度估算。请把机型和读数偏差发邮件告诉我们，我们会在更新中补充。
为什么 iPad / Mac 上不能测量
Tolero 按 iPhone 的屏幕密度换算长度，其他设备的屏幕参数不同，读数会不准，所以只支持 iPhone。
测量记录丢了
记录只保存在这台手机上。删除 App、抹掉手机或换新手机都不会自动迁移，我们也没有备份。
怎么删除我的数据
“更多 → 设置 → 数据 → 清空全部记录”。删除 App 会同时删除所有记录和设置。
购买与退款
Tolero 是一次性付费下载，没有内购和订阅，所以没有“恢复购买”。换手机或重新安装时，在 App Store 的“已购项目”里重新下载即可。退款请通过 reportaproblem.apple.com 向 Apple 申请，退款由 Apple 处理。

The reading is slightly off
Lay the phone flat, look straight down at the screen, and remove any screen protector before comparing. Screen manufacturing tolerance, protector thickness and viewing angle all add small errors that can’t be fully removed. Tolero is for everyday reference only.
“Current device” in Settings is wrong, or all readings are too big or small
The app converts pixels to millimeters using your iPhone model’s screen density. If your model isn’t in the built-in list, it estimates from the screen’s pixel density. Email us your model and the difference you see, and we’ll add it in an update.
Why can’t I measure on iPad or Mac?
Tolero converts length using iPhone screen densities. Other devices have different screens and readings would be inaccurate, so only iPhone is supported.
My measurements are gone
Records are stored only on this iPhone. They aren’t migrated when you delete the app, erase the phone or switch to a new one, and we don’t keep backups.
How do I delete my data?
Open “More → Settings → Data → Clear all records”. Deleting the app also deletes all records and settings.
Purchases and refunds
Tolero is a one-time paid download with no in-app purchases or subscriptions, so there is no “Restore Purchases”. On a new phone, download it again from Purchased in the App Store. For refunds, contact Apple at reportaproblem.apple.com; refunds are handled by Apple.
