Function Studio is genuinely the best app in the Shopify App Store. Partly because of its feature set and how you can build any sale you can dream up, but also has incredible support to back it up.

I've been very impressed across the board. We run sales with crazy levels of complexity, and the Flow structure is such an intuitive way to create these. Any minor bugs or challenges we've experienced were resolved in record time, including an entirely new feature that was built based on a few specific needs we had for free product gifting.

Overall, the best app money can buy now that Shopify Scripts is no more.

Thank you so much for this great review!

Your team really does run one of the most complex promotions we've seen so far, and it's great to see that the app keeps up with all of it.

Requests like yours are what push Function Studio forward - please keep them coming :)

Jonathan at Function Studio truly is the best Shopify vendor. He is so quick to respond and the tool is truly SO helpful. We've been able to do some really custom work in checkout that standard Shopify hasn't been able to support with. Can't recommend enough.

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 !
