The 4.16.1 version of Inxtify for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Design & Photo Tools, more precisely Viewers & Editors. We recommend checking the downloaded files with any free antivirus. The actual developer of this free software for Mac is Zhi-Wei Cai.
From the developer:
Inxtify is a feature-rich Instagram client and uploader for OS X. It supports uploading images and videos directly from your Mac by drag and drop. The tool allows you to change your profile picture and toggle your private account setting. You can use the app with multiple Instagram accounts.
