I was looking for a back-in-stock app that sends alerts via WHATSAPP. I found this. The pricing is fair, and everything seems so easy, I really don't even know how to explain it. I'm a happy user here! You guys are wonderful.

Simple app, does what a shopify store needs. Everything is well so far. I send automatic back in stock alerts when I bring more products in. and the support team - they are amazing and fast. What to expect more?
