VoxGuard is an Android call-screening app that protects you from spam calls, robocalls, and unwanted unknown numbers by screening every unknown caller before your phone rings. Instead of relying on spam databases that are always out of date, VoxGuard handles every unknown caller the same way: it intercepts the call, asks the caller to prove they're human, records why they're calling, and lets you decide whether to connect. Your saved contacts always ring through normally, so there are no delays for people you know.

Here's how it works. When an unknown number calls, VoxGuard answers first and asks the caller to repeat a short key phrase of your choice. Robocallers and automated systems can't respond correctly, so they get hung up on automatically after three failed attempts. Real human callers then record a brief reason for their call, which VoxGuard transcribes to text. You receive a push notification with both the audio recording and the written transcript, and you have two minutes to approve the call and have your phone ring, or decline it. Any missed or declined calls go to a smart voicemail with separate greetings for known and unknown callers, and every voicemail is transcribed for you.

VoxGuard works on any carrier and screens every unknown caller, not just numbers on a blocklist. You can customize your key phrase, record your own greetings or use text-to-speech, set the caller's recorded message as your ringtone so you hear who's calling before answering, and toggle screening on or off anytime.

VoxGuard puts you back in control of your phone by making sure only real people, with a real reason to call, ever get through.
