New app! Also: Xcode + iOS + iPhone 3G tip. Also: insane idea.

I have a new app on the iTunes App Store! Allow me to introduce The Beer Nerd’s Olde Volume Equivalence Calculator:

It’s a handy little app that lets you compare equivalent prices for different volumes of beer. Interesting? Maybe. In all honesty, I whipped this app up real quick for the following reasons:

1. It uses the new accurate UISlider subclass I’ve been working on (which I will open source soon!)
2. It has an iAd. Ooh or eew? I don’t know yet.
3. I’m trying something new to help increase my skills. It’s kind of like Jonathan Coulton’s Thing a Week. I intend to write and publish a new app every week for the next year. What?

That last item seems like it might be a doozy. Not every app is going to be a winner. Apple may kick me out for generating too much crapware. Most will be free or iAd supported. Some might be decent.

There is a lot of doubt entwined with this idea. But here is something about which I don’t have much doubt: writing and releasing an app a week will stretch all parts of my development skillset, from writing code to understanding design patterns to designing icons to submitting and packaging. We’ll see how this goes. App #1 is done, app #2 is waiting to be reviewed and app #3 is nearing completion. Also, I haven’t forgotten about Lens•Lab! I’ll count an update of that as part of an app a week.

Oh, and the Xcode + iOS + iPhone 3G tip is this: when you create a new project in Xcode 4.2, the plist for your app has a entry called “armv7” in the “Required device capabilities” section.

If your app targets iOS 4.2.1 and lower, you MUST remove this entry to support armv6 (the processor variant in the original iPhone, iPhone 3G, and 1st and 2nd generations of iPod Touch.) I just found this out this morning and an update to The Beer Nerd’s Olde Volume Equivalence Calculator has been submitted to Apple!

Lens•Lab for iOS development update.

Greetings, fellow photography nerds!

We’re working on an update to Lens•Lab for iOS devices. Here’s what we have in store:

• Editable constraints for focal length. For example, I can set the focal length to go from 24mm-85mm, just like the lens I currently have on my Canon 10D.
• Editable constraints for aperture. For example, I can set the aperture to go from ƒ/3.5 to ƒ/22, just like the lens I have on my Canon 10D.
• Aperture values are straight decimal values now. (They used to snap to 1/2 stop increments but now it’s more versatile.)
• A new Lens Information panel with the following information:
• Sensor Size & crop factor information.
• Angle of View (Vertical, Horizontal, Diagonal).
• Plane of Focus (Vertical, Horizontal, and Diagonal size of the focal plane.).
• …also for Depth of Field Near and Depth of Field Far.
• …and more!

We are excited about this release! If you are interested in trying this version out before it goes public, leave a message here or send an email to jmenter+blog [at] gmail [dot] com.

We are pleased to announce the release of Lens•Lab 1.0 for all iOS devices!

What is Lens•Lab? Here’s a short description:

Lens•Lab is a virtual lens simulation tool for photographers of all skill levels. It graphically illustrates how depth of field and field of view relate to your SLR camera and lenses.

Lens•Lab works with all iOS devices running firmware 3.0 or newer and works great with iPad and iPhone 4 retina displays!

MD5 Calculator Released for iOS Devices

We are pleased to announce the release of MD5 Calculator in the App Store!

What is MD5 Calculator? It computes an MD5 hash from text you enter as you type. Sweet!
