If you could only keep one app on your phone, what would it be?

5•brike•9mo ago
Imagine if you were allowed to use only one single application for your whole life. Who would you pick?

Comments

cranberryturkey•9mo ago
safari
brike•9mo ago
why not chatGPT/Claude etc?
cranberryturkey•9mo ago
i can do that with safari
shakna•9mo ago
Messages.
almosthere•9mo ago
assuming Phone is just a feature not an app, then maps
brike•9mo ago
interesting, I thought people are going to mention Notion, ChatGPT, tasks, but now maps:)

why it's the main app that you need? are you travelling a lot?

rolph•9mo ago
maps are the most useful on phone as you tend to take maps with you.

most other apps are sedentary.

dcminter•9mo ago
> I thought people are going to mention Notion, ChatGPT, tasks ...

I'd bet good money that most people have neither Notion nor ChatGPT apps installed on their phones. How many people do you think don't use Maps or an equivalent whenever they're away from home?

anenefan•9mo ago
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.
davydm•9mo ago
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.

brike•9mo ago
you had to have millions on your bank account if it's the most important app for you:)
KomoD•9mo ago
> but I could tell people they can only sms me.

Well, you wouldn't be able to keep the messages app would you? So they can't :)

Quinzel•9mo ago
Safari. Because at least you can access most other services from that. The navigation might be a bit shit, but you’re still connected.
brike•9mo ago
cheater....
dcminter•9mo ago
I mean "Firefox" was my first thought too, I blame the question ;)

Assuming pre-installed stuff is a given (in which case I guess I'm managing with Chrome) then here in Sweden I'd have to go with BankID so I could still do ecommerce stuff.

owebmaster•9mo ago
Definitely not safari because its PWA implemention is lame.
walthamstow•9mo ago
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

AznHisoka•9mo ago
My MFA app
Kuyawa•9mo ago
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.
koliber•9mo ago
Notion.

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

cafard•9mo ago
Weather.
Bender•9mo ago
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.
beAbU•9mo ago
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?

swah•9mo ago
Whatsapp but if I had no family then Safari.
chistev•9mo ago
Chrome
pajko•9mo ago
OsmAnd+
BOOSTERHIDROGEN•9mo ago
Ticktick
tobinfekkes•9mo ago
1password
codingdave•9mo ago
Merlin Bird ID.

I can do everything else at home on my PC.

runjake•9mo ago
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?

paulcole•9mo ago
I mean this is like picking “satellite phone” if you could take one thing to a desert island with you. Kind of a boring answer even if it’s technically correct.
barnacl437•9mo ago
yeah as long as you have given it sufficient permissions. but actually i dont know if it does count default apps already come with phone, otherwise you'll already get a shiny ooh quality neat-looking (not guaranteed) camera app for better use.
ValdikSS•9mo ago
Email client I guess.

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

paulcole•9mo ago
I’ll try to not be boring here with my answer.

If I could only do one thing with my phone (app-wise) it’d either be music or podcasts. If I had to pick one, I’d go with podcasts.

So I’m going to say my podcast app of choice, OverCast.

mikewarot•9mo ago
The actual phone call app, of course. It's not really a phone without it.
cypherg•9mo ago
Instagram because it's by far the app that gets the most use on an hour by hour basis. Endless content plus messaging.
d--b•9mo ago
2 Factor authentication.

I can do everything else on dumb phone + computer + camera, but 2FA is the reason I simply cannot drop the smartphone.

ValdikSS•9mo ago
There are feature phones which support applications (not Android-based), but indeed nobody made an OTP authenticator for it.
hulitu•9mo ago
> If you could only keep one app on your phone, what would it be?

The phone app.

barnacl437•9mo ago
does it count default basic apps already installed on phones? otherwise it wouldnt even form a thing. well, as most others, a browser.

but i think i am NOT a person for one-app phone. i tend to install a lot and just throw em off the memory lane.
