Wave Bar

Wave Bar adds a customizable announcement bar to your Shopify storefront in about a minute. Display one fixed message or create up to three rotating messages on a timer you control. Perfect for promotions, updates, or important announcements across every page. Add countdown timers when deadlines matter. Count down to a specific date or use repeating timers that automatically restart daily, weekly, or monthly. Customize your announcement bar with your choice of colors, fonts, and links. You can also let shoppers close the bar if needed. The app uses theme app embed technology, so there's no theme code to edit. Set separate text sizes for mobile phones and desktop to ensure your messages read well on all devices.
