Our Shopify apps // 03 apps

Apps for the jobs every store runs.

Our apps cover the common jobs: scheduled sales, parts fitment and bundles. When your store needs something they don't do, our team builds the custom part around them.

App 01

PreSet Promo

Status
● Live on Shopify
Plan
Free plan available

Flash sales on a schedule. Announcement bars, countdown timers and automatic discounts start and end on their own, with ready Black Friday, Cyber Monday and Christmas templates.

App 02

PreFit Pro

Status
● Live on Shopify
Trial
14-day free trial

Year / Make / Model (YMM) fitment search and a parts finder for parts and batteries, size search for wheels and tires, and a “Fits your vehicle” check on product pages, so fewer wrong-fit returns.

Bundles & upsell

A bundle builder for step-by-step routines, like a skincare routine: a price on each step and a bundle discount that applies itself.
