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.
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.
