These are the apps I find most useful. I compiled the list just by reading the app icons off the first and second screen of my iPhone. The only apps on this list are ones that I’ve been using more than a month, to prevent infatuations from getting listed.
Tweetbot ($3). My favorite Twitter client. Mac bloggers can get rhapsodic and precious in their Tweetbot reviews. I just like Tweetbot. It’s fun and easy to use.
Instagram (free). My love for this free social photo-sharing app snuck up on me. I thought I was just trying it out, and then I tried posting a couple of photos, and a few months later I was hooked. Whereas Flickr seems to have gotten crustier over time with useless features, while failing to keep up on essential capabilities, Instagram does everything a photo-sharing site should and very little that’s unnecessary. Using Instagram, you can post photos, write captions, share with other people, view photos from other people, Like photos, leave comments, share on Facebook, Twitter, Tumblr, and other social networks, and that’s about it. It’s like Twitter for photos. Oh, crap, now I’m the one sounding precious, aren’t I?
I can do without the filters on Instagram, but everybody else seems to like them.
Foursquare (free). I check in regularly. I don’t know why. I never get any offers. Rarely, someone I know has checked in at the same location, but if they’re there I almost always know it already. And yet I still keep tapping that button.
Lose It! (free). Keeping a food and exercise journal is key to losing weight and getting fit; you need to write down every bite you eat, and every time you work out. That’s important for two reasons: For controlling the amount of food you eat, of course, but also to become conscious and mindful of what and when you’re eating.
Most fat people aren’t mindful; they just eat compulsively and automatically. Keeping a food journal requires you to be aware of what you’re putting in your mouth.
I weigh and measure every meal and snack. I take precise measurements with a scale when I’m home, often down to the gram. When I’m out, I estimate. Lose It tracks the calories of those foods, and also the calories burned exercising, and does so with an easy-to-use and attractive interface.
This year, Lose It added a bar code scanner, which has proven very useful; when I’m eating packaged food like a frozen dinner, I just scan the barcode with the iPhone camera and Lose It automatically tallies the calories.
Lose It’s database and calorie calculations aren’t the greatest. I find that most of the foods I eat aren’t in the database; I have to add them manually. Fortunately, I only have to do that once for each food; after that, Lose It remembers. Likewise, I’ve had to adjust my daily calorie budget; Lose It’s recommendations are way off. But Lose It makes it easy to do those things.
I use Google to find the calories of any foods that aren’t in the database. For example, Google grilled turkey and brie sandwich and you’ll get several entries; I just pick the median amount and enter it in to Lose It.
RunKeeper (free). I use it to track the duration and distance of my daily walks.
Both Lose It and RunKeeper have social features and badges that I don’t pay any attention to, with the exception of posting my RunKeeper results each day to Facebook.
Weightbot ($1.99). Lose It lacks a good diary for keeping track of your weight over time; it’ll tell you what you weighed last time you weighed yourself, but not what you weighed six months ago. That’s what Weighbot is for. It’s less important now that I’ve hit my goal weight, but I keep it up anyway.
Podcaster ($2). I listen to hours of podcasts every week, and Podcaster does a better job managing them for me than the native iPod app. Podcaster does automatic, over-the-air updates of new podcast episodes, and lets me create a playlist and listen to one podcast after another without having to manually start each one.
Audible (free). Audiobooks.
OmniFocus ($20). The iPhone version of the ultimate to-do-list management app. I also use the iPad and Mac versions. Mainly, I use the Mac version, and use the iPhone version to add new items.
Due ($5). Reminders and timers. I use it instead of the built-in iPhone timer for a couple of reasons. One is because it supports pre-set alarms. For example, I have a pre-set configured at 5 minutes to time steeping tea, and another at 32.5 minutes for the turnaround point on my walk.
The other reason I prefer Due to the built-in timer is you don’t have to press a button to turn off; it rings for a second or two and then shuts off on its own.
Since this fall, iOS 5 has its own reminders app; I haven’t compared Due with that.
Due has many other capabilities, but I don’t use most of them.
GV Mobile+ ($3). My preferred Google Voice client for the iPhone. I bought it before Google had its own, official client. It’s not so much better than the official client that I’d recommend others pay for it.
Soulver ($4). Better than the iPhone’s built-in calculator; it displays results adding-machine-tape style. You can also include words in your calculations.
TomTom USA ($40). GPS and turn-by-turn directions.
1Password ($8.99). Password management. One version runs on the iPhone and iPad, and it syncs with a version for the Mac. Essential for generating secure passwords, and remembering my hundreds of passwords for Web sites and networks.
Chipotle (free). Very nice mobile commerce app; it remembers our weekly order, and, with a couple of buttons, we order, pre-pay,then I drive over, cut to the front of the line (without making eye contact with anyone in the line — that’s important), pick up and go. I’ve been trying to get an interview with Chipotle about this app for The CMO Site for months; if you have any connections over there please let me know.
