Very simple system that effectively lets only legitimate calls through. Call forwarding required for use, but easy to set up. Thank you for giving us back control over our phones! ### 5/5 — Wow, it’s about time! *2022-02-20, version 1.0* I just started using Call Cleanser. It actually does what it says and stops robocalls before your phone rings. I have used most of the other “so called” robocall blockers. They still have your phone ring and annoy you just to say this could be a robocall. Isn’t it better to stop them before your phone rings? ## Frequently asked questions about Call Cleanser Spam Blocker App ### How does Call Cleanser block robocalls?
