YouTube/Twitter/Facebook - Medium IMPACT
I have a Twitter account for AppCycles and a Facebook Page for AppCycles to make my brand look more legit – but it definitely does not drive a lot of downloads. All it does it make people like my app more, which can lead to more purchasing, the better likelihood of being featured on a review site, and people telling their friends.
Both YouTube and FB are free, and I would definitely recommend doing them. If you have an app that needs even the slightest of explanations, it’s a good idea to have a YouTube video that walks through someone using the app.
