Boomerang covers screen time. Anchor closes the bypass routes.
Boomerang Parental Control blocks new app installs but does not stop the four core bypass routes: uninstall, clock change, factory reset, permission revocation. Anchor closes all four. The Child app survives uninstall attempts, reads time from the server, and the parent gets tamper alerts when permissions are revoked.
Boomerang and Anchor both target screen time control on Android. The difference shows up at the bypass routes: where Boomerang blocks new app installs and enforces schedules, Anchor adds the 4-layer moat that holds against uninstall, clock manipulation, factory reset, and permission revocation.
Boomerang Parental Control is a screen time and app-install blocking product for Android (with iOS support per its documentation), priced at $19.99 per child device per year or $39.99 for a 10-device license per year, Verified May 2026. Anchor is a bypass-resistant Android parental control with a 4-layer moat architecture: watchdog-protected Device Admin (Layer 01 TAMPERING), server-truth time (Layer 02 CLOCK), parent-side pair persistence (Layer 03 RESET), and offline tamper queue (Layer 04 OFFLINE). Boomerang covers the screen time use case and notifies parents of new app installs. Anchor was engineered against the bypass routes kids actually try on Android: uninstall, clock change, factory reset, permission revocation. Anchor's Family is $4.99 per month for up to 4 child devices, Family Pro is $9.99 per month for unlimited devices, both with a 14-day free trial requiring no card at signup. The first 100 founders get lifetime free Family Pro through the Founders Offer. Anchor is Android-exclusive at present, with other platforms on the roadmap without committed timing.
Side-by-side: Boomerang vs Anchor
Capability comparison across primary architecture, pricing, platform, and the four bypass routes documented in Anchor's Bypass Test methodology.
| Boomerang | Anchor | |
|---|---|---|
| Primary architecture | Screen time enforcement + new app install blocking + parent notifications | 4-layer moat against bypass routes (Tampering, Clock, Reset, Offline) |
| Platform | Android and iOS per Boomerang documentation | Android-exclusive at present, other platforms on roadmap without committed timing |
| Pricing model | Per-device per-year license: $19.99/year/device or $39.99/year/10-device license | Flat subscription: Family $4.99/month for up to 4 devices, Family Pro $9.99/month unlimited |
| Free trial | Not documented as a primary feature | 14-day free trial, no card required at signup, billing begins day 15 |
| Bypass Route 1: uninstall block | Not documented as a defense layer | Holds via watchdog-protected Device Admin (Layer 01 TAMPERING) |
| Bypass Route 2: clock change | Not documented as a defense layer | Holds via server-truth time (Layer 02 CLOCK) |
| Bypass Route 3: factory reset | Not documented as a defense layer | Partial: re-pairing requires parent code via parent-side pair persistence (Layer 03 RESET) |
| Bypass Route 4: permission revocation | Not documented as a defense layer | Holds via watchdog plus offline tamper queue (Layers 01 + 04) |
The primary architecture differentiator
Boomerang
Boomerang's primary architecture is screen time enforcement with app install blocking on Android. The product notifies parents of new app installs on the child's device, blocks the new installs by default, and supports schedule-based screen time limits. The architecture is designed around the cooperative supervision use case: visibility into what the child is doing, and limits on when they can do it.
Anchor
Anchor's primary architecture is bypass-resistant enforcement on Android. The 4-layer moat (Watchdog-protected Device Admin, Server-truth time, Parent-side pair persistence, Offline tamper queue) was engineered against the bypass routes kids actually try when supervision stops being cooperative. Schedule rules and app blocking run inside the moat, so the rules hold even when the kid tries the documented bypass routes.
Time and scope handling
Boomerang
Boomerang's schedule enforcement is per-device, per-year licensed. The schedule rules run on the child device. The pricing model means each kid device the family wants to manage requires a separate license, or a 10-device pack license covers up to 10 child devices for the year. The architecture treats each device as an independent licensed instance.
Anchor
Anchor's schedule enforcement runs on server-truth time, evaluated against the Anchor backend timestamp rather than the device clock. Schedule decisions hold even when the child changes the device clock. Pricing is a flat household subscription: Family at $4.99 per month for up to 4 child devices, Family Pro at $9.99 per month for unlimited child devices. Adding a kid does not add a license fee on the Family Pro tier.
Bypass behavior
Boomerang
Boomerang's product documentation focuses on app install blocking and screen time enforcement. The bypass routes documented in Anchor's Bypass Test methodology (uninstall the parental control, change the device clock, factory reset, revoke permissions the parental control depends on) are not specifically addressed in Boomerang's marketing materials. This does not mean Boomerang fails all four routes definitively; the documented defenses focus on a different parental concern.
Anchor
Anchor was engineered against those four bypass routes specifically. The 4-layer moat is the architectural response. Per the Bypass Test methodology verdicts: Layer 01 holds against uninstall, Layer 02 holds against clock change, Layer 03 holds Partial against factory reset (the wipe succeeds but re-pairing requires the parent's six-digit code), Layer 04 plus Layer 01 hold against permission revocation. Every tamper event surfaces to the parent feed in real time if online, queued with original timestamps if offline.
What each app uniquely does
Boomerang
Boomerang uniquely notifies parents of new app installs on the child device. The kid installs an app, Boomerang notifies the parent. For parents whose primary concern is "what did my kid just install," Boomerang covers that visibility directly. The product also handles per-device licensing in a way that lets families pay per kid as they add devices.
Anchor
Anchor uniquely runs the 4-layer moat. Watchdog-protected Device Admin holds the uninstall block at the OS level while detecting permission revocation attempts within seconds. Server-truth time evaluates schedules against backend timestamps so device clock manipulation has no effect. Parent-side pair persistence holds the household binding through factory reset. Offline tamper queue preserves tamper events with their original timestamps when the device is offline.
What Boomerang does well.
Boomerang is a credible product for parents who want screen time control plus visibility into new app installs on Android. The product is well-established with a clear focus on screen time enforcement and app install monitoring. For parents whose primary concern is "did my kid install a new app I should know about" combined with basic schedule limits, Boomerang covers that use case directly. The per-device pricing model is straightforward for families who want to manage costs per kid rather than committing to a subscription. Boomerang has a longer market history than Anchor and a documented track record on Android.
Why this matters.
Screen time control and bypass-resistant enforcement are different parental concerns that benefit from different architectures. Screen time tools focus on the cooperative side of supervision: setting limits, monitoring usage, getting alerted when something new appears. Bypass-resistant enforcement focuses on the moment supervision stops being cooperative: when a kid tries to defeat the limits you set.
Boomerang's architecture, focused on screen time and app install blocking, fits the cooperative-supervision use case. The product was not designed against the bypass routes documented in Anchor's Bypass Test methodology. Per Boomerang's own product documentation, the defenses are around app blocking and schedule enforcement, not against uninstall plus clock manipulation plus factory reset plus permission revocation.
Anchor's architecture is the opposite end of the spectrum. The 4-layer moat exists because the parental control market has a structural gap: cooperative-supervision tools work until the kid stops cooperating. Anchor was engineered against that moment. If your concern is screen time monitoring with app install visibility, Boomerang covers that. If your concern is rules that hold against a motivated kid, Anchor closes the routes Boomerang does not document defenses against.
