Average lift from mobile-first stack builder
Supplement stacks are 3-5 products. Building a 5-product stack on a 6-inch screen needs a UX designed for mobile, not squeezed from desktop.
The hacks
Vertical stack builder with swipe-to-add
Each supplement in the goal stack shows as a card. Swipe left to skip, tap to add. A running total and savings counter update in real time. Three taps to build a 3-product stack.
Mobile-first supply duration selector
Three large buttons: "30-day ($34)," "60-day ($62)," "90-day ($85)." Per-day cost shown on each. One tap selects the supply duration. Tiergain renders mobile-first supply selectors.
Sticky "complete your stack" bar on mobile
Sticky bar: "Complete your recovery stack - add BCAA ($26, save 15%)." Visible as the customer scrolls. The bar surfaces the missing piece of the stack without interrupting browsing.
Mobile cart drawer with stack completion
Cart has protein + creatine. Cart drawer shows: "Complete recovery stack - add BCAA for $26." The cart drawer suggestion catches the customer at peak buy intent on mobile.
One-tap post-purchase stack addition on mobile
After mobile checkout: one big button - "Add fish oil to your stack - $22." Supplement buyers on mobile are still in health mode. One tap to add to the shipment.
Subscription toggle on mobile bundle completion
After building the stack on mobile: toggle - "Auto-ship monthly (save 15%)." The subscription toggle right after stack building captures commitment while the customer is still in health-goal mode.
Count the taps from landing to cart
A mobile supplement stack should go from product page to cart in 4 taps maximum: tap stack tier, tap supply duration, tap add-to-cart, confirm. Every extra tap drops mobile conversion 7%. Count your taps.
