assuming Phone is just a feature not an app, then maps

I'm in a very rural area so the first on any cheapie android phones is a good GPS program - doesn't need mobile network coverage to get position, time and speed of travel.

Banking - no ways I want to waste time at a physical bank.

Sure, I'd miss all the messaging channels, but I could tell people they can only sms me.

Safari. Because at least you can access most other services from that. The navigation might be a bit shit, but you’re still connected.

Google Maps or OSMAnd, assuming I get phone calls and texts for free.

Banking I can do on a computer, I live in a place with great public transport so losing Uber would not be the end of the world

My MFA app

Brave. I could access the whole world with it, no ads, AI at my fingertips, maps, banks, crypto wallets, chats, apps, there is absolutely nothing I can't do and if there is, I'd build it.

Notion.

Or the Telephone app that allows me to make phone calls, if we are pedantic.

Weather.

SMS/Texting. All I use the phone for is voice and text. In fact I miss my old Danger Sidekick II for its nice physical keyboard, tiny phone with a slide-up screen. It was perfect for me.

OP, from your replies here it seems you came into this with your own opinions.

What is the one app you would keep, and why is it ChatGPT?

Whatsapp but if I had no family then Safari.

Chrome

OsmAnd+

Ticktick

Merlin Bird ID.

I can do everything else at home on my PC.

The web browser of course. It can do most anything an app can do including taking photos and recording audio.

I don’t know if there is another correct answer, right?

Email client I guess.

Basically the only thing I really miss in the feature phones is email client.
