Features & Capabilities

Callblock is a Chrome extension that blocks unwanted calls and telemarketing attempts. It leverages the world’s largest directory of telemarketers—millions of entries across 100+ countries—to identify known callers and prevent nuisance interruptions.

With simple setup and clear caller controls, you can manage blocked numbers, create whitelists, and tailor how calls are blocked, all while prioritizing privacy and user control.

User Reviews

User feedback is mixed but leans positive on Callblock’s core promise: it blocks spam calls widely thanks to a large, community-driven block list and a clean, easy-to-use interface with a trial option. However, recurring issues include billing confusion and immediate charges, difficult cancellation, and inconsistent performance across devices and updates. Some users report loading problems, bugs in toggling block status, and over-blocking legitimate numbers like employers. Overall, many users value the protection and affordability, but reliability and support concerns keep ratings uneven.
Pros
  • Effectively blocks spam calls and telemarketers for many users.
  • Large preloaded block list and community-driven database (millions of numbers).
  • User-friendly interface and straightforward onboarding.
  • Free trial available and affordable pricing.
  • No ads and easy to add custom numbers.
Cons
  • Billing and trial issues: charges occur immediately, confusing cancellation, and poor support contact.
  • Inconsistent performance: effectiveness varies; some spoofed numbers still get through.
  • Reliability issues on certain devices (e.g., iPhone X) and occasional loading/UI bugs.
  • Free vs paid expectations: app appears free but requires subscription to function.
  • Blocking legitimate numbers (e.g., employer) or critical contacts.

It states this has a free trial for a month & will charge your $19.99 a year or monthly & upon downloading it I was charged immediately after I picked which subscription & free trial. States it will charge again for the same amount next month even with the year subscription. PLEASE fix this!!!
