Fossify Contacts and Fossify SMS Messenger (Fossify is a fork of Simple Mobile Tools) are now available, joining Fossify's existing suite of Gallery, File Manager, Phone, and Calendar apps.
(ICYMI, Simple Mobile Tools suite was acquired by an adware company and their apps on the Google Play Store now contain trackers and unnecessary permissions. This report from Exodus shows that the old version of Simple Gallery had 0 trackers and 10 permissions, whereas the app, after sale, contains 9 trackers and 21 permissions!)
About Fossify: Fossify is all about community-backed, open-source, and ad-free mobile apps. A fork of the SimpleMobileTools, which is no longer maintained, and we’re here to continue the legacy, bringing simple and private tech to everyone.
The creator of the Simple apps sold them to an advertising company, which has since added trackers into the apps. The fossify project is forking all of them to keep them tracker free and to continue development.
It is unlikely the new owners will add trackers to the f-droid versions, if only because they won't be updating the apps on f-droid ever again. So while you would be safe from trackers, there's not really any downside in switching to the Fossify versions to be able to receive any future updates and security fixes.
