Tap an equireelz link on your iPhone — in a message, an email, or Safari — and it opens straight in the app instead of the browser.
A link to a single shared video opens that video's page in the app. A link to a multi-video share opens the shared list inside your Videos tab. If you don't have the app installed, the link opens the normal web page instead, so it always works either way.
Some links need you signed in
A share link plays right away — no account needed; after watching you can create a free account to keep the videos. Videos shared directly with your account, though, only show once you're signed in.
