I can't vape weed with my phone yet.

Electric Toothbrush. Keeping up with Dental Hygiene is important too!

A Vibrator.

Cameras. You can take pictures with your phone, but despite Apple's advertisements, a phone camera will never produce anywhere near the same quality a dedicated digital camera with interchangeable lenses. And neither are as good as film.

Radiation detectors. Such as the Radiacode or the Open Gamma Detector.

Binoculars are quite portable, very useful, and phones don't do a good job at zooming in like that.

Smart watches integrate with phones but the phones by themselves are not so good at measuring the heart rate and other parameters directly.

Mini projectors. UV flashlights. Tools in general... There is so much actually. What type of gadgets are you looking for?

Flashlights. Again, in an emergency, you can use your phone. But it's not as good as a real flashlight, and I always carry and use a flashlight.

Hi-fi audio recorders with builtin microphones. As a bass player, I deeply resent phone mics and speakers.

I was just thinking this morning that it's kinda odd that there's no cell phone that also doubles as a multi-meter for measuring electronic current. I guess it's because in theory you'd need to also carry around a set of probes with you?

Video games. At least for me. Mobile games suck.

Shank

Laptops! I have a gaming desktop computer and also a gaming laptop that I use if I'm going to be somewhere other than my house for more than a day. Mobile games pail in comparison to what can be played on a decent gaming laptop. I wouldn't even think about trying to run even a rudimentary 3D game on my 3~ish year old smartphone which has 3-5 seconds of input lag for everything LMAO

Honestly most of the non digital functions of a phone are still inferior to it's dedicated counterparts, but I would argue that a phone is good enough for 99% of people.

So get a pocket multitool thingy, I always carry one in my bag and it has helped me quite a few time in my life.

Knife/multitool. There is a plethora of options. I enjoy the classic swiss army knife. Scissors, pincet, knife, saw, bottle opener, pliers... You can get it all in one small package.

Headphones/earphones can't be an app.

Cup/bottle/thermos/liquid container. Drink more water, enjoy hot coffee.

A skill. Spend time getting good at some random non virtual things, penspinning, coin tricks, cardistry, calligraphy...

Pagers for Hospitals.

Vicegrips. Wirestrippers. A light screwdriver with common bits carried on its handle like a Sidewinder. Rake lockpick. SDR. Elevator key. Punch. File. Multimeter. Multitool with good pliers. Crank radio. Survival guide. Poncho. Silver exposure blanket. Fire starters. Multihammer thing. MREs. Good flashlight. Beater laptop like an old x200. Serial console adapter. Flares. Camping stove. Throw it all in a bugout bag after you learn how to use them.

• A pocket notebook and a ballpoint pen, for quick note taking. Edit: add to that a pocket watercolor set and a brush, for quick sketching
• A pocket book, for on the go reading
• My (mechanical) wrist watch

I don't care if the smartphone can be used to take notes, to read and has an extra precise clock. I much prefer my analog tools. They don't require upgrade, they don't need recharging, no one will ever try to stole them (my watch is not fancy at all, it's just mechanical ;) and, well, I prefer using those.

I'm posting these separately so people can argue about specific devices.

A calculator is still better than a phone in a lot of cases. I haven't yet met a financial advisor who uses their phone instead of a calculator. It's often the same issue as with keyboards: touch screens are simply vastly inferior to tactile keys. Few people are willing to carry keyboards around with them, but for those who use calculators a lot, for many it's worth having a portable, dedicated device.

Books.

The kindle app might be convenient but it's shit compared to an actual book.

My hands.

Pocket knife. Although I wouldn't be surprised if there's a phone case out there with a box-knife-like insert for a razor blade.

...infact, brb.
