Ask Lemmy

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.

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.

A Vibrator.

I can't vape weed with my phone yet.

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.

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

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

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?

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.

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