  1. To my mind, one more quality call blocker Android users can opt for is Nize by Cube Apps. Works perfectly on my Android smartphone.

  2. Avast is the worlds best spamware. If you choose to download & install anything this company has made available, you will find it almost impossible to rid yourself of this horrible nuisance. Extremely resource heavy. YOU DO NOT WANT TO USE ANYTHING BY AVAST!!!

  3. people making calls from using wephone app and the no appears from +1 or so Seems to be from US but it routed through wephone server. is thr any option we can block calls from wephone app in IPHONE.

  4. Call and SMS blocker apps are a need of every user these days because the spam calls are very annoying especially in the office hours. Sometimes we rush to the cellphone that it might be an important call but it turnout to be a spam call. Majority of the smart phone provide the SMS and call blocking future out-of-the-box but the blocker apps provide more advanced features.
    Thanks for sharing collection of apps. They will certainly be helpful for every user.
