InstaGrabber

InstaGrabber is an app that allows downloading Instagram posts (and, in fact, an open-source drop-in replacement for the Instagram app, but with only read functionalities).

This app is originally made by @AwaisKing who posted on GitLab. I decided to continue the app cuz why not, even though it might not be that cash money. (Also I need to learn Java.)

Download

Download here. Under each release is an app-release.apk. Just install that. Unfortunately,

• I have to sign it with my own key, which means you have to uninstall the old app and log in again. Sorry.
• I don't plan on getting a Google Play Dev account yet, so that means Google Play will shout at you for installing "malware". Just ignore it. If you're skeptical (which is not necessarily a bad thing), just inspect the source code and build the app yourself.
