Ha. I used to be like you rsch, wondering why people need this stuff. Then my employer gave me a 3310, then a better but still basic Nokia, then a smartphone. I now own my own having moved on job wise.
Apps then eh? First off, you install what you want. Some come preloaded but most can be deleted, or hidden away from the main screen. It’s your phone to use how you like. As you mentioned ‘stupid apps’ I thought I’d see what mine are…
Text: ubiquitous, doesn’t impact data and all packages these days have unlimited texts. A great way of exchanging non urgent info.
Whatsapp: brilliant. I have groups for immediate family, my rapidly aging siblings, the people who until March I spent most days in the office with and still appreciate informal interaction, and a few others, plus individuals. There’s the Executors group that I run dealing with my late parents’ estate - so easy to exchange imformation, or when an important letter arrives the other exec can take a photo and I can see it 2 seconds later. Plus unlimited video & voice calls when on wifi, but even on data these don’t take much.
Online banking. So useful, so handy, and no need to be near the PC or a need to fire it up to check or make a payment.
Nextdoor: local social media thing. It’s good, I’ve sold a lot of stuff on there that didn’t warrant eBay fees, and given away as well as recieved lots of free stuff; instant recycling. Useful for knowing too what’s going on locally now that the local paper has gone.
Twitter: I look occasionally. Not vital, nice to have.
BBC Sport: largely redundant in lockdown but generally v useful, easily customised to suit my interests.
Lottery: Yh, I want a Statement and a Bentley with Naim in it. I don’t need to remember to go to the shop to get a ticket, and it tells me when I win.
Outlook: Email is still a thing.
BBC Sounds: Love this. Twitter often mentions a great prog on R4 etc. Fire Sounds up, Bluetooth into the Muso, the 272 or the car, and it’s there.
Podbean: my podcast app of choice. There’s a world of interest there if you look. Download a podcast, chuck the phone on the car seat and play it through the car audio. All that took was a one-off 30 seconds of pairing - BT > Pair > select the Volvo, done, now everytime I get in it’s ready to go.
Naim: well you just would.
Waze: sat nav with voice in the car for the odd time I’m going somewhere new.
Duo Mobile: 2FA security thing used mainly by our IT dept, and others. V useful.
ParentMail: our sons’ school’s preferred method of communicating with parents. They also send emails but PM is a much neater interaction.
Dropbox: getting files off, more useful when it was an iPhone but Android works with USB. I could lose this.
WhatThreeWords: geographic location appp. V useful, esp when I met up with the wife at an unknown remote spot after lockdown eased. Emergency services use it too.
Trainline: buy tickets, check on train schedules, all from the pub or the work party you’re at.
GooglePay: converts my phone to a contactless payment vehicle without the contactless limit, with each transaction listed with all required details other than what I actually bought.
Maps: in a strange town? The answer.
NSandI Prize Checker: I win some interest most months on Premium Bonds, this is the neatest way to check when you’re out or without having to access login credentials,
Phone: useful thing a phone…
Camera: Excellent quality pics all the time, or like when I was out in town & saw an ad in a window for a job that would suit my younger son. I could have found a pen & paper, or just take a photo & Whatsapp it to him. He got it.
Chrome Browser: the internet
My watch app: links phone to watch, it counts steps like a Fitbit, the phone can trigger the camera remotely, control audio on the phone, and synch the time. Great, background app that makes life easier.
There are more. None are stupid, all have varying degrees of usefuleness but no-one said we can only use phones for serious things. And like you 20 years ago I had your view, but these things make life easier, esp Whatsapp & being an executor. The benefits totally outweigh any downsides. The phone was free btw, I take on my sons’ cast-offs as they become available. It works for me, and for them.
