"Efficient, Reliable & Seamlessly Integrated!" Using FAST – WhatsApp Chat has significantly improved the way I connect with customers. The integration was smooth, and the app is impressively lightweight without compromising functionality. Real-time communication is now just a click away, which has boosted both customer satisfaction and conversion rates. I especially appreciate the intuitive design and prompt support whenever needed. Highly recommended for any store owner looking to strengthen their customer engagement!

What else can you ask for? A simple yet intuitive app that lets you connect with your customers through WhatsApp. Customizable and programmable, suitable for small businesses. Our experience has been good, which includes testing. Edit: One of the features we love about it is page-specific deployment of a floating widget with a smooth entrance animation. We use it only on the Contact page, which looks niche.

I've just set up this app and think I got lucky because it was free (for now). It's simple yet exactly what I needed to help my customers reach out to my small business via WhatsApp. The staff helped me set up a couple of final steps and ran a test to see everything was working ok. Great customer support and I wish the company the best of luck!

The app is extremely useful and easy to integrate! I wanted the WhatsApp button to appear on my product pages, and Grace from the support team went above and beyond — not only guiding me but personally configuring the placement for me. Her support was quick, professional, and very helpful. Highly recommended for anyone wanting smooth WhatsApp integration!

Fast installation. I had a doubt and it was solved fast, well not, actually inmediate response. The whatsapp button looks nice, it has a fast response. Just as expected! Recommend 100% for a simple and fast working solution
