Frequently asked questions

How much does BlockerX cost?

When we checked, blockerx.net listed Premium at about $110 a year or about $200 for a lifetime plan, shown as discounts from higher list prices. App store prices can differ.

Does ZenTab have an accountability partner?

No. ZenTab relies on delay instead: an urge challenge when you hit a blocked site, and a 30-minute wait before Pro protection can be switched off. Most urges pass well within that time.

Can ZenTab block adult sites on my phone?

Yes, for free. The guides at zentab.live/protect set up a DNS filter that blocks adult sites in every browser and app, private tabs included.
