Prefixer

Prefixer is an innovative application designed to enhance your calling experience with an array of customizable features. Its primary purpose is to allow users to pre-configure rules that automatically prefix, suffix, or replace numbers during calls. This utility is particularly useful for individuals who often adjust call numbers to fit specific calling plans or organizational needs.

The app boasts an easy-to-use rule-based system where you can create a variety of conditions and corresponding actions, making it highly adaptive to unique requirements. For instance, this handy tool can recognize number patterns through regular expressions, differentiate contacts by labels and groups, consider your roaming status, network operator, and even your current location. It is also equipped to handle different SIM slots, WiFi connections, and can be programmed according to the day and time.

You are empowered to modify call notifications by customizing vibration patterns, text, and display features. It also provides options for call confirmations with several innovative modes, including a 'party mode' to prevent accidental calls when you might not be at your most attentive. Additionally, features an auto handle function for managing calls automatically, which can be extremely convenient for multi-tasking users.

Another significant advantage is the convenience of sharing and managing rules. You can easily exchange rules through QR codes, web links, or files, and have the option to backup or distribute complete rule sets as needed.

While the application is free to use, it does have some restrictions which can be lifted through an in-app purchase. Without this, the functionality is limited to one rule each for outgoing and incoming calls. Users should also be aware that optimal functionality is achieved when installed directly on the phone’s internal storage, especially to maintain widget functionality.

Noteworthy is the dual SIM support; however, it’s important to recognize that this feature is experimental and may not function perfectly on all devices. The tool currently supports multiple languages, and updates are continuously in progress to expand this list for a broader user base.

Overall, Prefixer is an essential tool for anyone looking to streamline their call handling process, providing a highly personalized and controlled calling environment right at your fingertips.
