The screen resolutions for Apple’s various iOS devices are:
* new iPads and iPad Minis: 2048 x 1536
* old iPads and iPad Minis: 1024 x 768
* iPhone 5s and new iPod Touches: 1136 x 640
* iPhone 4s and old iPod Touches: 960 x 640
If I want a minimum size for their to be a sidebar, 1000 pixels looks like a good minimum.
The [Nook app for iOS] has been updated to include assistive technologies of *zoom* and *voiceover*. (H Who knew they had an app? Given Amazon’s DRM and their tendency to nuke your content and ask questions later, Barnes and Noble has an opportunity here to be the “other guy.” Amazon played that role well for years. B&N needs to catch up. Voiceover is a step in the right direction.
**Update**: Oooo, you can lend books to friends. I think B&N just did something there.
**Added note**: Sorry, Amazon, your insistence that voiceover cuts into audiobooks would mean a little bit more if you hadn’t already acquired Audible. Some of the package deals being offered are getting more interesting, but I don’t think consumers are going to make the leap until the packages for a book include the codex, the ebook, and the audio version approach something like the $25 price point. Maybe $29. The codex, the physical book, may be optional in the near future, but until Amazon makes its DRM and licensing more consumer-friendly, I just can’t risk going all in with digital versions of books.

I’m still thinking about creating an iOS app for field researchers. If I do, then I definitely want it to have a decent-looking icon. [Icon Resources](http://www.iconresource.net) offers a series of tutorials and materials that are useful — and the designer behind them has nice taste.
[Google premières 3D imagery on iOS devices](http://google-latlong.blogspot.com/2012/07/3d-imagery-now-available-on-ipad-and.html). It’s not through the Maps application but through Google Earth for iOS, and it appears only to work on the iPhone 4S, iPad2, and the new retina iPad. (Was I the only person who didn’t know Google Earth was available on iOS?)
I have done a lot of quick design projects in applications like PowerPoint, OmniGraffle, and lately Keynote. (I have Illustrator, but it can be tedious to use for small projects.) Apparently others do, too, and there are some great resources for prototyping with Keynote:

And for that iPhone application I am thinking about: [Glyphish](http://glyphish.com/).
I must be getting old. I can’t find an e-mail link or any other route to offer feedback to the developer of an app of which I am very fond, [Day One](http://dayoneapp.com/). I tweeted the developer, but my tweet got picked up by a service of some kind and the developer came back mostly cranky.
In the mean time, here are my Day One app improvement suggestions:
* Give me a way to edit the style sheet for how my text appears.
* And then make sure my text also appears that way when it prints.
* Then give me a way to export more than one entry at a time: what if I want to print and bind a year’s worth of entries? No way to do that.
* And here’s my cool UI idea for the day: make it possible for a user to make their “inspirational” thought for the day be the post for that day from last year. Implementing that will make you a real leader in the journaling space.
I’ve written about Day One before, both in [comparison to MacJournal][mj] and as part of [how and why I blog][hw].
Sometimes the universe whispers in your ear when you are headed in the right direction. I have been thinking about developing an app for the iPhone which would be built for field researchers like myself, and then I came across this on [Kottke]: [Start Developing iOS Apps Today].
