KwikPass: OTP‑login & Popups vs PAS Product Availability Slotsfor Shopify (2026)
KwikPass: OTP-login & Popups and PAS Product Availability Slots, while sharing the 'Promotions - Other' category on the Shopify App Store, cater to vastly different merchant needs. KwikPass focuses on lead generation, user identification, and boosting sales through phone-based login and engaging popups. It aims to convert anonymous visitors into identifiable leads and increase conversions using features like 'Spin the Wheel' and retargeting. In contrast, PAS Product Availability Slots addresses the challenge of managing product availability, allowing merchants to schedule specific dates, days, and time ranges for product sales, creating urgency with countdown timers, and hiding prices and 'add to cart' buttons when products are unavailable. The core difference lies in their purpose. KwikPass seeks to improve user engagement and streamline the login process for increased conversions. Its strength lies in its ease of use - 'automatically added to Shopify' - and value proposition of turning anonymous shoppers into identifiable leads. PAS Product Availability Slots, on the other hand, targets merchants needing to control when their products are available for purchase. Its value proposition is offering control over product availability and creating a sense of urgency. This app is most beneficial to businesses with limited stock or service providers who have specific time slots available.

Common Questions
Which app is better for increasing overall store conversions?
KwikPass: OTP-login & Popups is designed to increase conversions by making it easier for users to log in and by using popups to engage visitors and offer incentives. PAS Product Availability Slots doesn't directly focus on overall conversion rates.
If I sell pre-orders, which app would suit me better?
PAS Product Availability Slots would be the better choice, as it allows you to schedule product availability and display countdown timers to create anticipation for pre-orders. KwikPass does not offer scheduling of product release/availability.
Which app is easier to set up and use?
Based on the description, KwikPass: OTP-login & Popups seems easier to set up, as it states that it is automatically added to Shopify. PAS Product Availability Slots likely requires more manual configuration to set up schedules.
Can I use both apps together on my Shopify store?
Potentially, but their functionalities are largely independent. KwikPass focuses on login and lead generation, while PAS Product Availability Slots focuses on product availability scheduling. There might be some minor conflicts, but testing in a development environment is advised.
Does either app offer A/B testing for popups or availability schedules?
Neither app description explicitly mentions A/B testing capabilities. KwikPass allows for retargeting visitors, which implies some form of segmentation, but not direct A/B testing. PAS Product Availability Slots makes no mention of A/B testing for schedules.
