Description

From the listing uploaded by “appupdater”.

ISY Block – friendly and simple calls and SMS blocker App With ISY Block you can: Block incoming calls from any individual number from Contacts - Block incoming calls from certain numbers (international, private, unknown, short) - Block individual number from Contacts with playing intercept message “This number is no longer in service” - Block incoming SMS - Block SMS and/or incoming calls from groups of contacts - Monitor blocked calls and SMS from blocked log - Turn on silent mode (both for calls and SMS, and for other notifications in your phone) or configure it manually. Why ISY Block was created: We believe that everyone has rights to his own privacy. Life is fleeting. We deserve to decide by ourselves who to bring closer and whom to remove from it completely. ISY Block is an easy solution that helps to take over control of life. Why ISY Block is better than others? - it's simple. Laconic design, intuitive menu, the most simplified procedure of locking / unlocking - It’s lite. Only 5 MB for downloading, low memory and battery consumption - it’s convenient. You can block calls from a certain number but allow to receive SMS from it (and vice versa) - it’s flexible. Blocks hidden, unknown, international, short numbers not only permanently, but on a schedule as well (for example, while you are in roaming) - It keeps your secrets. ISY Block is protected by password from prying eyes. Downloading ISY Block, you automatically get a free add-on ISY Messenger, which allows you to manage SMS blocking log autonomously from blocking calls. ISY (I Silent You) Block is an App with which you can hear only those you really want to hear. Questions and suggestions: 1. What should I do if I found a bug?

ISY Block APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is ISY Block free?

The APK is free to download, but the app offers in-app purchases through Google Play.

Is the ISY Block APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 49bcd74a47d3c2873091f48d49904efb.
