This app is great, and the customer support area is even better! Mike was extremely helpful in helping us setup the app and working through some issues of our own making. Highly recommend.
Fast service, looks great, easy to use. For more advanced changes you need to know some CSS coding, but you could also ask customer service and they will help you. Good product so far. April 2026
App is great. Also, they have excellent service. No matter if you are doing the free service or paying monthly, they are there to help.
It is listed as free in the Shopify App Store, but it actually costs money if you have more than 30 subscriptions per month... Would be nice to have some transparency to compare before installment.
Great app which is suitable for our product warranty registration needs! Fast and efficient support from the team too when we encountered an issue with the app during usage. Recommended!
Migration support varies by app and category.

AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
