I have just recently discovered this product, so I haven't been a frequent user in the past.
However, due to my interest in starting getting into ice baths, I see the value of having a one stop space to find the best places wherever I am.
I have a couple of suggestions to improve the UX/UI of the product:
1. Ask me where I am (country would be good, or city) since I don't se a lot of value in having a lot of different spaces that are not suited for me showing up as soon as I land on the homepage.
2. The description that we have of each store / spa could be a little more thorough, as right now the stores and the spas have the exact same content. It could be the differentiating factor / a selling point, something that would tell me that I should click on one instead of the other.
3. As I am new in this world, I am not sure it would make sense, but having a price estimating or starting from could also be a good approach, since it would allow me to filter if the budget is a deciding factor for me. (Could also work well as a feature, although maybe in the context of checking the different location it could help to decide.
Overall, it's definitely something I see myself using and these little tweaks could definitely elevate the experience further!
