Codeinero

Overview

Codeinero builds Shopify apps and has done so since 2015. Its two apps are Sticky Add to Cart Booster Pro, which adds cart and checkout shortcuts to a store, and Sales Rocket, which adds pop-ups, countdowns and other conversion widgets. They are meant to help merchants with cart abandonment and conversion.

For Shopify brands

• ●The sticky add-to-cart bar, sticky cart icon and sticky checkout bar keep purchase options visible as shoppers scroll.
• ●The Ajax cart slider shows in-cart upsell offers so customers can see more products before checkout.
• ●Rocket's sales pop-ups, email capture pop-ups, stock counters and countdown timers are in one app, and the listing says it does not change theme files.

How it works

Merchants install the apps from the Shopify App Store and turn features on in the app dashboard. The Rocket listing says it installs within a minute without development resources, and the STKY countdown timer setup is described as taking under 2 minutes.

Pricing

Sticky Add to Cart Booster Pro has a free plan (up to 25 add-to-cart clicks a month) and monthly plans from $6.99 to $29.99 by Shopify plan; annual plans run $60 to $250. Sales Rocket lists $5 and $9 a month on its pricing page; another page lists different amounts.

• ●Sticky Add to Cart Booster Pro Shopify app with a sticky add-to-cart bar, quick buy button, Ajax cart slider and countdown timer.

Integrations

Buyer notes

• Pricing is based on the merchant's Shopify subscription plan.

• Sales Rocket FAQ says it does not change theme files and leaves no code after uninstall.
• Support Center is listed as available 24/7; the Sales Rocket plans include free onboarding and support.
