We've rebranded! Welcome to Flash Apps by Fluorescent (Formerly Obsidian)


Powerful bundle recommendations to boost your sales in a flash

Boost sales by offering product bundles

Give your customers added incentive to purchase more! Suggest bundles of up to 10 products to your customers and offer a discount when items are purchased together.

Auto or manual bundle recommendations

Our streamlined setup experience means you can opt for auto recommendations and a quick setup, or choose to manually personalize bundle suggestions.

Built using a powerful app block system

Made for Online Store 2.0, our app blocks can be added anywhere. Use the theme editor to edit the appearance to align with your theme and brand.
