Do app blockers actually work?
App blockers can help reduce access during a planned focus period, but the effect depends on the person, settings and whether the limits stay enabled. Research on blocking mobile internet has found short-term benefits; it does not prove that every blocker works or that a counter is better. Silverback offers a different approach: counting short-video scrolling without blocking apps.
The short answer
App blockers can be useful. Their effect depends on the task, the settings and whether you keep them enabled. There is no evidence here that Silverback is more effective than blocking.
What does research show?
A 2025 randomized study of blocking mobile internet reported short-term improvements in attention and well-being. It tested a broad internet block, not just a Reels limit or Silverback. It cannot establish which approach will work best for you over time.
When might a blocker help?
- When you want a defined period without a particular app.
- When you can set limits that fit your work, study or family needs.
- When access restrictions are useful alongside reminders or a usage record.
A limit you repeatedly turn off may need adjustment. That does not mean blocking fails for everyone.
How is a counter different?
| Tool | Main role | Limitation |
|---|---|---|
| App blocker | Restricts access according to its settings | Restrictions may be overridden or disabled |
| Scroll counter | Shows the number of videos you scroll | It does not prevent continued use |
Silverback is a counter for Instagram Reels, YouTube Shorts and TikTok on Android. It shows your count and a gorilla reaction when you pass your chosen daily goal. It does not close apps or lock the phone. This describes the product; it is not a proven treatment or an efficacy claim.
