青灯墨屏是一款极简的阅读显示预设工具。 它把 iOS 系统自带的显示与辅助功能,整理成适合不同场景的「墨色」预设: 墨读:灰度 + 白点 + 减弱动态,适合长文、通勤和日常阅读。 深读:灰度 + 白点 + 亮度 40% + 减弱动态,适合强光、户外和需要更压光的场景。 夜读:灰度 + 白点 + 亮度 40% + 夜览 + 减弱动态,适合睡前和暗光环境。 青灯墨屏不需要账号,不接入广告,也不接入第三方统计 SDK。 日常切换可通过 Apple 官方「快捷指令」App 完成。你可以把这些预设放到控制中心、Action Button、Back Tap、Siri 或辅助功能入口中,用更少的步骤进入阅读状态。

HeiLock helps you set gentler boundaries around app time. When it is time to stop, pause for a moment, cut down on short, mindless bursts of app use, and use apps with more intention. Key features: • Session Limits Set how long an app can be used each time. When the limit is reached, usage is restricted automatically. • Cumulative Limits Set a cumulative usage limit for one or more apps. When the set time is reached, usage is restricted automatically. When you select multiple apps, use “Combined Usage Time” to choose how time is counted: when enabled, usage time across the selected apps is combined, and the apps share a single cumulative limit; when disabled, usage is accumulated separately for each app. • Allowed Time Windows Choose when an app is available. Outside those windows, usage is restricted. • Custom Display Content Add your favorite photos or videos. When an app is locked, HeiLock can show the content you selected, making each pause feel a little warmer. • Manage Multiple Apps Manage multiple apps at once and set different usage schedules for different apps. • Passcode Protection Protect your settings with a passcode to prevent unwanted changes. • Local Storage No sign-in, no ads, and all data stays on your device.
