I cant tell you how much this app has solved a problem i had instantly. Saved me alot of money as well. Most developers were asking me to pay for shopify plus. Bharat was very helpful and instantly solved the issue i had in my checkout. I really appreciate and highly recommend the app.

Tweakday Checkout has a very clear and intuitive UI. Within just a few minutes we were able to set up checkout rules, adjust the order of payment methods, and even customize the names of payment methods. These are features that Shopify does not provide out of the box, but this app makes them possible, even in the free version.

We compared it with five other checkout rules apps, but either they did not work properly or they required payment even for the smallest tweak. Tweakday clearly stood out.

I had been looking for a simple checkout validation app to display an error message on specific checkout fields for certain countries for ages..tried many, but they either didnt function well or required Shopify Plus accounts.

I was so happy to find Tweakday Checkout! I had a small issue with display on my theme, but support (from Baharat) was fantastic, and their UI is super simple and intuitive to use.

Definitely recommend this app for simple checkout validations and rename/hide/reorder for payments & delivery fields.

Thank you guys!
