Each HomeStack App has a custom landing page (referred to as a DeepLink) that we recommend you use on all marketing pieces. This is the same link that you can text/email through the Invite Friends feature.
Each link looks like this: bk.homestack.com/YOURAPPNAME
If a client accesses your link from a mobile device/tablet their app store will pop up with the option to download the app. If accessed from a desktop computer they will see this page below.
This webpage has Direct download links for the Apple App store or Google Play Store. See example below.
