Great app and great support. It allow to make almost everything as a plus merchant, without needing to hire and deploy a custom app to make logic customizations !
Great app to have in your toolkit, the flow like function builder makes it easy to build, and test, before activating.
Działanie tej aplikacji nas zawiodło i postanowiliśmy ją odinstalować. Zniżki nie wyświetlały się za każdy razem na każdym komputerze.
This app is all kinds of amazing. Perfectly handles all the edge cases we've needed covered, and the team are always looking to increase the functionality of the app when a gap is found. The flow interface is fantastic, the support is next-level awesome, and Jonathan personally goes the extra mile. Highly recommend this app!
This app is incredible. It offers virtually everything you could need for discounts, validations, and checkout transformations, with an exceptional level of flexibility. The support team is equally outstanding. Responsive, knowledgeable, and always willing to help.
We’ve had an outstanding experience with this app and can highly recommend it to any team looking to optimize their checkout process. The app is incredibly easy to use and integrates seamlessly into our workflow. It effectively solves common challenges around displaying delivery methods, making the entire checkout experience much clearer and more user-friendly for our customers. One of the biggest advantages for us is the ability to block specific products directly in the checkout. On top of that, the app allows us to prevent certain product combinations, which has been essential for avoiding invalid or problematic orders. Overall, we are extremely happy with this app. It has become an essential part of our setup, and we can wholeheartedly recommend it to others.
This is by far the best discount app that uses Shopify Functions, and it’s not even close. The flow makes discount logic much easier to build, visualise, and understand. They also have the best support I’ve experienced. Jonathan has helped me through countless edge cases and has never once failed to deliver.
Excellent functions for advanced logic required to make better discounts that have a superior UX which drive higher revenue in return. Customer support is also great with the app which makes all the difference.
Function Studio FAQ

Best suited for stores using EComposer & Foxify, Hydrogen & 2048 Variants and Monster Cart Upsell, which it integrates with and willing to start free and move to $25/mo.
There is a free plan, paid plans start at $25/month, and run to $199/month across 4 published tiers. Prices are as listed on the Shopify App Store and can change — confirm before installing.
Function Studio's plans are separated by features rather than by store size — none of the tiers is capped on a volume you could state up front. Compare what each step adds over the one below it rather than trying to size yourself into a tier.
