For those not aware and especially those coming from Parler, there is no app for Gab, but you don't even need one. The dev team here stripped TENS of THOUSANDS of lines of code out of the Gab front-end last year to make it as lean and mean as possible and run smoothly via a simple mobile web browser. Gab has been designed specifically to run without an app or any dependance on the app store, and is battle hardened to withstand tyrannical deplatforming.
So I'll say it again. You don't need an app, but if you want an "app like experience" you can install Gab as a PWA (progressive web app) on both Apple and Android. Mobile web browser is all you need. For desktop, download and install the Dissenter web browser, and there's actually an option to install "Gab Social" in a similar manner which runs off of the Dissenter browser back end, and gives you an app-like experience on the desktop also.
All of this is the exact opposite of all of the Big Tech products that specifically scuttle their mobile web performance to rope you into the app so that they can spy on you, collect all of your data, eavesdrop on your conversations, look at all of your photos, and track your location. APPS ARE EVIL. As for Parler, I could never get their platform to run well even with an app, and forget it with a mobile web browsing experience. They're going to get completely deplatformed from AWS in the coming days if not weeks, at which point they'll be finished completely. Gab owns all of their own servers and has stacks of them coming in, and cannot be deplatformed.
That is all. Welcome aboard!
