Apps in Paris ?

I've not used any of the apps you have listed but I do have CityMapper which I use for the Metro and like a lot. Some of the folks who live in Paris and are on the forum use this. I find it more user friendly than the RATP app but YMMV.

I also have the G7 taxi app downloaded. I put my hotel address in as "home" so I don't have to type it out every time, lol.

Thank you Pam. I'll download Citymapper. And you reminded me that I had downloaded G7 after reading a recommendation on this forum. I need to locate the G7 app icon on my phone and move it to my "travel" category grouping along with my airline and Rick Steves apps.

This is what I recommend (and use myself):

For restaurant reservations - call the restaurant or use their own website to reserve (many restaurants now use zenchef).

For walking - Google Maps. Alternatively, I use Open Street Map.

For public transportation - Citymapper or Île-de-France Mobilité app.

If you have an Android phone, your phone becomes a Navigo Easy card replacement using the Île-de-France Mobilité app and a linked credit card.

For taxi service - I use Bolt.

"I need to locate the G7 app icon on my phone and move it to my "travel" category grouping along with my airline and Rick Steves apps."

Have you been looking at my phone, lolol??? I move the Citymapper to my front page while I'm in Europe and then move it back to to my "Europe" folder after I return home.

RATP also has an app called Bonjour RATP, which I prefer slightly to IDF Mobilités for design reasons, though the two are not perfectly overlapping in terms of functionality.
