My Smartphone has Replaced these Things

I’ve noticed that I use my iPhone for a bunch of stuff that I used to have another device or system for. Here’s what I mean:

• Paper plane tickets: I recently started using e-tickets with the iPhone’s Passbook. Works great, and I don’t have to carry rumpled-up paper tickets anymore.
• Guitar tuner: I use Guitar Toolkit for that. It’s actually the most accurate tuner I’ve ever owned!
• Metronome: I now have lots of app-based metronomes, so there’s no need for a hardware-based metronome anymore.
• Drum machine: I tend to use drum machines for metronomes. On my iPhone, I use DrumTrack8, and on my iPad, I use DM1. Both are fabulous.
• Alarm clock: I use the built-in Clock app, and it works great. No need for a travel alarm clock, or a hotel wake-up call anymore!
• Bible: YouVersion from Lifechurch.tv. Coolest Bible app ever.
• Camera: I still use fancier cameras, but for a simple point-and-shoot? My iPhone is great at that – as long as I don’t need to zoom.
• Encyclopedia: What’s that? I have Google/Wikipedia/etc. In my pocket.
• Newspaper: There are a TON of news apps. I do most of my iOS news reading via the Flipboard app.
• Weather radio: I live in Kansas. I need to know when those tornado warnings go off. My TWC Max app from The Weather Channel goes off when the weather does.
• Notebook: See my last post on iA Writer and Byword. But I still like a good Moleskine notebook and a pencil, too.
• Calculator: the default iOS calculator app is always with me…
• Calendar/Daytimer: Currently using Tempo and Any.DO for these.
• Exercise book or video: Currently using the brutal YAYOG (You Are Your Own Gym) app. Pretty handy!
• Voice recorder for reminders: There are a ton of apps for this, too. I frequently use Evernote for this.
