Scored on 419 merchant reviews we hold for Swym Back in Stock Alerts, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 419 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 419. Open one to read it in full, with the developer's reply where there is one.

It was a pretty good app, but now it's paid only. The entry level plan costs almost as much as Shopify itself.

Srihari and the team were able to resolve the issue efficiently and provided outstanding support throughout the process. Their assistance was greatly appreciated, and it’s reassuring to know that we’ll be in safe hands should any future issues arise.

Update: This issue seems to finally be resolved (within a few hours of posting a review). Once we've had a chance to test it in a real-case scenario with a multi-sku restock we will update our review. We've been using this app for several years. It has been great...until recently. For some reason the app now requires a wait of several hours before the inventory numbers sync and "stick" between Shopify and the app's system and results in the BIS alerts not being sent when triggered manually. This causes multiple issues and prevents us from really using the app (that we are paying a pretty hefty fee for!) to its full potential. It makes it extremely difficult to time promotions, etc that are related to restock events. We have been in contact with the developers about this issue for the last 6 weeks. They have finally acknowledged that the issue exists, but have still not been able to resolve it. We've spent countless hours trying to get to the bottom of the issue and create work-arounds for a service we're paying the app to do. If they are not able to resolve soon we will be exploring other options.

This app has worked very well for us and has led to many sales when an item comes back in stock. Their support team is very responsive if an issue ever arises.

This app worked well for me. It did everything I wanted it to. Adding the "Notify Me" button to my products was simple. My only criticism is that the interface to get reports or to make changes to notifications is clunky and not user-friendly. It took an hour on their chat to get a notification message updated. Other than that, everything works great.

We had back in stock alerts set to manual send only but the app just randomly started sending out hundreds of back in stock alerts for products that were still out of stock. Really poor experience for our customers and very embarrassing for us.

Developer repliedThank you for taking the time to share your valuable feedback. We are disappointed to hear that your experience with our app did not meet your expectations. On paid plans, our app is designed to send out the back-in-stock notifications automatically to the subscribers as soon as we receive a restock update from Shopify. Please be assured that our systems are designed to send notifications only when products are restocked with a positive stock quantity. One potential cause for the issue you faced could be due to the multiple store locations feature in Shopify. Even in that case, our app can be configured to provide better control over the restock alerts based on locations. We tried reaching out to you via email so that we can set up the app in a way that is more suitable for your business model and we are waiting to hear from you. If you are still interested in exploring the benefits of our back-in-stock app, please don't hesitate to contact us at your convenience via email. We are dedicated to assisting you and enhancing your experience with us. Show more

We've had a great experience with this app in the years that we've been using it. The Back in Stock form is clean and quick to load. We recently updated our theme and had some issues with the layout and size of the form, but Josiah from the Swym Support Team had us fixed up in a matter of hours. Nice!

This app has been very helpful so far. The support team is very responsive to messages and made custom adjustments to the look of our back in stock form and button as well.
