Fossify Messages is a free SMS and MMS app for Android that carries no ads and is released under the GPL-3.0-only licence. The version covered here is 1.10.2, updated on October 27, 2026, and it needs Android 8.0 or newer. The package ID is org.fossify.messages, and the developer is Fossify.
Free, no ads, no price tag
The app is free and has no ads. There is no paid tier. The store text says the app does not ask for unnecessary permissions.
The source code is public at github.com/FossifyOrg/Messages under GPL-3.0-only. That means anyone can read it, and the developer points to this for security and privacy audits. The app is tagged open-source, phone-and-sms and no-ads in the catalog.
Blocking, backup and lock screen controls
The core job is sending SMS and MMS messages, including group messages that run over SMS or MMS. Photos, emojis and quick greetings are part of the composing side.
Blocking goes further than a simple number list. It can stop messages from unknown contacts, and it can filter messages that contain specific words or phrases. Blocked numbers can be exported and imported, which helps when moving to another phone.
Messages themselves can be exported and imported as a backup. The developer describes this as the way to switch devices without losing conversations. A search function is included for finding older messages without scrolling.
Privacy settings cover the lock screen. You can show the sender only, the message content, or nothing. Material design and a dark theme option round out the look.
A 6.5 MB package from a small project
The download is 6.5 MB, which is small for a messaging app. The app handles SMS and MMS through the phone's own connection rather than an online account.
The first release was on January 26, 2024. The latest update is dated October 27, 2026, at version 1.10.2. The developer site is fossify.org.
