Best Free App Blocker for Android in 2025 — Tested and Ranked
2025年 Android 最佳免费应用屏蔽器——测试与排名
The Test: Can You Bypass It in Under 60 Seconds?
The real test of an app blocker is not "does it block by default" but "can a distraction-seeking version of yourself get around it." We tested four popular options with a simple bypass protocol: uninstall the app, disable it in settings, use a different app, or ignore its notifications.
App 1: Google Digital Wellbeing
Built into Android. Sets daily time limits per app. Once the timer expires, the app's icon is greyed out.
Also bypassable by: opening the app in a browser, disabling Digital Wellbeing, or using a different Google account. Effective for people who genuinely don't want to use an app — useless for fighting addiction.
App 2: AppBlock
Schedules app blocks with a timer. Offers a "strict mode" on paid plans that makes it harder to disable.
The paid strict mode is better but still doesn't use Device Admin or VPN enforcement. Power users on Android can disable Accessibility Service from developer options without AppBlock noticing.
App 3: Freedom
Cross-platform blocker that uses a VPN to block at the network level. Blocks websites and apps together.
Freedom's VPN enforcement is real but fragile on Android. It's also $84/year. No content-specific blocking. No Device Admin enforcement — can be uninstalled.
App 4: FocusFlow (Free, Open Source)
Three-layer enforcement: Accessibility Service + null-routing local VPN + Device Administrator.
- Cannot be uninstalled during a session (Device Admin)
- VPN cannot be disabled — attempts trigger session violation alert
- SHA-256 PIN protects session settings
- Boot recovery restarts enforcement after device reboot
- Clock tamper detection
- Sideload Guard — newly installed apps blocked automatically mid-session
Side-by-Side Comparison
| Feature | Digital Wellbeing | AppBlock | Freedom | FocusFlow |
|---|---|---|---|---|
| Price | Free | $2.99/mo | $6.99/mo | Free |
| Accessibility enforcement | No | Yes | No | Yes |
| VPN enforcement | No | No | Yes | Yes (local) |
| Device Admin (uninstall block) | No | No | No | Yes |
| Reboot protection | No | No | No | Yes |
| Content-specific blocking | No | No | No | Yes (Shorts, Reels) |
| Temptation log | No | No | No | Yes (500 entries) |
| Open source | No | No | No | Yes |
| No data collection | Collects usage data | Partial | Collects usage | Fully local |
Verdict: Who Should Use What
- Casual user who checks phone occasionally: Digital Wellbeing is fine.
- User who needs cross-device blocking (Mac/Windows too): Freedom, despite the price.
- User who wants hard enforcement on Android for free: FocusFlow.

测试：您能在 60 秒内绕过它吗？
应用屏蔽器的真正测试不是"它默认是否屏蔽"，而是"一个想要分心的你能否绕过它"。我们用简单的绕过协议测试了四个流行选项：卸载应用、在设置中禁用它、使用不同的应用，或忽略其通知。
应用1：谷歌数字健康
内置于 Android。为每个应用设置每日时间限制。计时器到期后，应用图标变灰。
也可以通过以下方式绕过：在浏览器中打开应用、禁用数字健康或使用不同的谷歌账户。对真的不想使用某个应用的人有效——对抗上瘾毫无用处。
应用2：AppBlock
用计时器安排应用屏蔽。付费计划提供"严格模式"，使禁用更难。
付费严格模式更好，但仍然不使用设备管理员或 VPN 执行。Android 上的高级用户可以从开发者选项禁用无障碍服务而 AppBlock 不会注意到。
应用3：Freedom
跨平台屏蔽器，使用 VPN 在网络层面屏蔽。同时屏蔽网站和应用。
Freedom 的 VPN 执行是真实的，但在 Android 上很脆弱。而且每年 $84。没有内容特定屏蔽。没有设备管理员执行——可以被卸载。
应用4：FocusFlow（免费，开源）
三层执行机制：无障碍服务 + 本地空路由 VPN + 设备管理员。
- 会话期间无法卸载（设备管理员）
- VPN 无法禁用——尝试会触发会话违规警报
- SHA-256 PIN 保护会话设置
- 设备重启后启动恢复重启执行
- 时钟篡改检测
- 旁加载保护——会话期间新安装的应用自动被屏蔽
