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.

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.

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.
— Boody Australia
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.

Hands down the best support, I have ever experienced from a Shopify app provider. Furthermore the app has helped us strengthen our cart and checkout even more. Thanks a lot Jonathan!

This app did exactly what we needed it to do for our tiered automatic discounts for Black Friday. Jonathan was super helpful and responsive for helping us get everything set up, highly recommend this app!
— The Carnivore Bar
woww! I wanted to create one discount code with multiple variations of discount percentages. This is the Best app I've used for discounts and the customer service is spectacular. Thank you for saving my black Friday sale
— Protein Pouf
I've tried 6+ discounting apps and Function Studio is the most robust and customizable. I really dig the flow interface. Discounts are our main focus with this app right now but I'm excited to explore some of the other use cases! Jonathan is responsive and clearly working hard to keep the app functional and at the cutting edge of new policies and features that Shopify releases.
— Highland
Buena aplicación para configurar ofertas y combinar productos de varias colecciones. Recomendada

Best app I've used for functions. Hands down the easiest to use. Jonathan is super responseive and helpful and already released updates for some of our edge cases. 100% recommend this app!
— Powertec
Jonathan and the team are doing amazing work with Shopify Functions. It’s the only discount/function app we’ve found that supports fixed‑final-price bundle discounts and lets the same product/SKU live across multiple bundle groups. Highly recommended.
— LSKD
Extremely useful! Thank you!
— Nuzzie
Quite possibly the best new app we've come across. This unlocks the full capabilities of Shopify functions in a clean and simple-to-use way. Nothing better than finding gems like this, and they just work!
