Zangi - Private Messenger

Signing up without a phone number sets Zangi - Private Messenger apart from most chat apps. Published by Secret Phone, Inc, it assigns each user a Zangi Number instead, and it builds its pitch around keeping conversations and contact details away from strangers.

Registration needs no SIM card and does not ask for the phone's contact list. Other users can only reach someone who has shared their exact Zangi Number with them, so profiles cannot be found by searching, which is meant to cut down on unwanted contact. Once connected, people can chat, make voice and video calls and exchange files and media. The developer states that messages are stored only on the device rather than on its servers, and that texts, media, files and calls use AES-GCM 256 end-to-end encryption. It also says the app is built to cope with slow or unstable internet connections, where other messengers can struggle.

Zangi has 50,000,000+ installs and a 4.2 average from 279,246 ratings, with 68% five stars and 11% one star. There are no ads, and in-app purchases range from $1.49 to $59.99 per item. It was updated on 2026-09-03, runs on Android 6.0 or newer and is rated Everyone. We list 38 versions; 6.6.0 is the newest at 66.3 MB.

People who want a messenger that is not tied to a phone number, or who worry about being found by strangers, will appreciate the approach. Because history stays on the phone, users should consider what happens if the device is lost.
