Shopify store owners love STOQ

The best back in stock app I've found. Design capabilities are simple, but sufficiently sophisticated. Functionality is great. Kartik provides great app support and is very responsive. Would recommend, and the same cannot be said for the majority of the apps in this category.

I highly recommend this app. The app itself is easy to use and has the ability to customize it to fit your theme. It gives you metrics to track that the app is worth the cost. Plus, it doesn't affect website performance at all. The support is friendly, helpful, and quick to respond. Can't go wrong with this app.

This app is FANTASTIC. It is well built, easy to integrate/use and pays for itself. Kartik is a great developer and quick to respond to any issues occurring on your site. We had a novel problem due to us using half Pagefly pages and half Shopify product pages for awhile and Kartik fixed it within a day. In just a few months we've already racked up $5,000 worth of recovered sales and that number will only grow as we do. Well done Kartik!

One of the BEST apps I have ever used for Shopify. It is user friendly, easy to set up etc. Side note - The customer service is amazing and super fast!

If you are looking for a back-in-stock app that offers multi-language capability and real double-opt in as required per GDPR, look no further, this is it. Most of the other back-in-stock apps just say they are GDPR compliant, but when it comes to double-opt in via e-mail, they got nothing to offer. Also, most other of those apps don't offer multi language input for form and mail texts. This app here however has it all. The app works smoothly and is easy to use. All in all, one of the best app experiences. Keep up the good work Kartik!
