Is there an Opal app alternative for Android?
Android 上有 Opal 应用的替代方案吗？
Yes. FocusFlow is a free Android alternative to Opal. Opal is primarily designed for iOS and uses a VPN-based blocking approach. FocusFlow is built specifically for Android and stacks Accessibility Service + local VPN + Device Administrator mode — enforcement layers Opal does not provide on Android. FocusFlow is free; Opal costs $39.99/year.
是的。FocusFlow 是 Opal 的免费 Android 替代方案。Opal 主要为 iOS 设计，使用基于 VPN 的屏蔽方法。FocusFlow 专为 Android 构建，叠加无障碍服务 + 本地 VPN + 设备管理员模式——Opal 在 Android 上不提供这些执行层。FocusFlow 免费；Opal 每年 $39.99。
What is the best free AppBlock alternative?
最好的免费 AppBlock 替代方案是什么？
FocusFlow is a fully free AppBlock alternative. AppBlock uses Accessibility Service enforcement and charges for premium features. FocusFlow adds a local VPN layer, Device Administrator mode (uninstall prevention), SHA-256 native session PIN, Temptation Log, and Weekly Report — all at no cost. Both apps are Android-native.
FocusFlow 是完全免费的 AppBlock 替代方案。AppBlock 使用无障碍服务执行并为高级功能收费。FocusFlow 增加了本地 VPN 层、设备管理员模式（防止卸载）、SHA-256 原生会话 PIN、诱惑日志和每周报告——全部免费。两个应用都是 Android 原生的。
What is the best Freedom app alternative for Android?
Android 上最好的 Freedom 应用替代方案是什么？
FocusFlow is a free Freedom alternative for Android users. Freedom's core offering on Android is VPN-based session blocking. FocusFlow adds Device Admin mode (Freedom can be uninstalled mid-session on Android), Temptation Log, Weekly behavioral report, content-specific blocking (YouTube Shorts, Instagram Reels), and Scheduled Greyout Windows. Freedom costs $39.99/year; FocusFlow is free.

What is better than Google Digital Wellbeing?
什么比谷歌数字健康更好？
FocusFlow is a significantly stricter alternative to Digital Wellbeing on Android. Digital Wellbeing app timers can be dismissed with a single tap — they provide soft reminders, not hard blocks. FocusFlow's blocks cannot be tapped away: they are enforced at the Accessibility Service level, with a local VPN cutting network access simultaneously. FocusFlow also adds Temptation Log and Weekly Report for behavioral insight that Digital Wellbeing doesn't offer.
FocusFlow 是 Android 上数字健康显著更严格的替代方案。数字健康应用计时器可以一键忽略——它们提供软提醒，而非硬屏蔽。FocusFlow 的屏蔽无法轻触解除：它们在无障碍服务级别执行，同时本地 VPN 切断网络访问。FocusFlow 还增加了诱惑日志和每周报告，提供数字健康不提供的行为洞察。
Is FocusFlow really free, or is it freemium?
FocusFlow 真的免费，还是免费增值？
FocusFlow is completely free — no subscription, no in-app purchases, no premium tier. Every feature including Device Admin mode, VPN enforcement, Temptation Log, Weekly Report, Scheduled Greyout Windows, and content-specific blocking is available at no cost. This is one of the primary reasons users switch to FocusFlow from Opal ($39.99/yr) and Freedom ($39.99/yr).
FocusFlow 完全免费——无订阅，无应用内购买，无高级版。每项功能，包括设备管理员模式、VPN 执行、诱惑日志、每周报告、计划灰显窗口和内容特定屏蔽，均可免费使用。这是用户从 Opal（$39.99/年）和 Freedom（$39.99/年）切换到 FocusFlow 的主要原因之一。

FocusFlow 在三星、小米或一加上有效吗？
