Nice and easy to set up! And it's very straight to the point. I hope it helps re-gain clients and convert lost sales.

Using this app for the first time, the UX/UI is intended for a novice, which makes every so simple rather than any coding needed, WHATSOEVER. Great that it's free but I will also wait to see how my customers find it too. Really hope to see positive results! ---------------------------------------------------------Update (20mins later): Unfortunately, doesn't work on mobile, it's an overlay on desktop - is there a way to get this on mobile? as most of my customers would be using mobile devices. Turned the app off for now.

Hi there,

Thank you so much for the review. The iPhone does not currently support browser notifications, however, we are releasing the ability to send emails very soon that will be used when a customer is browsing from an iPhone. Apologies for the hassle in the meantime, I will follow up once this feature is released 😊
