Introduction
Fossify Contacts is an open-source address book from Fossify, the community project that took over the Simple Mobile Tools apps after they were discontinued in late 2023. It carries on from Simple Contacts Pro.
What it does
From the project’s README and the app itself:
- The usual address book fields, and you choose which ones to show.
- Groups for emailing or texting several people at once, and favourites.
- Import and export contacts as .vcf files; exports use vCard 4.0, and it can import vCards that other apps share with it.
- Private contacts, stored on the phone where other apps can’t see them. You can let Fossify Phone, Messages and Calendar show them.
- Merge duplicate contacts: an option that shows contacts with the same name as one entry in the list. In the source code it only combines them on screen, and the stored contacts stay separate.
- Automatic backups, and an optional dialpad button.
Sync
Fossify runs no sync service. Contacts sync through the accounts already on your phone, such as a Google account, or through a sync app such as DAVx⁵ for a CardDAV server. The APK doesn’t request internet access.
About this file
- This is Fossify’s own build of version 1.6.0, from January 2026, delivered through IzzyOnDroid and signed by Fossify. It is byte for byte the APK on the project’s GitHub release and the one F-Droid distributes.
- Fossify says its Google Play and F-Droid releases use the same package name and signing key, so this file can be installed over the Play version when it is the same version or newer.
- The 8.6 MB file runs on Android 8.0 and later and declares 9 permissions.

Can I install this over Fossify Contacts from Google Play?
