announcements for store

I Recently came across an application focused on in store marketing rather than bringing in new foot traffic.

The idea is to announce promotions through short, professional audio messages just by text while customers are already browsing the aisles, instead of relying on signage or staff announcements.

What stood out to me is how low effort it seems no recording, no technical setup, just typing a message that plays automatically. It feels more like in the moment marketing compared to online ads, since customers are already inside and ready to buy.

It looks especially relevant for grocery stores, pharmacies, and hardware stores where impulse purchases matter most near checkout.

For those running physical stores have anyone tried in store announcements before?
