Many of us are forgetful in some form, and this trait is especially magnified when one proceeds to show others an "awesome photo" on your iPhone that, sadly, didn't get synced. Instead of telling your friends that you'll show or email them the photo later -- assuming you even remember to -- you can use Simplify Photo to view your entire iPhoto collection.
While increased megapixels in digital photography brings with it the promise of better picture quality, in most cases it comes at a file size premium. And because storage space on your iPhone is a finite resource, you can choose to set aside dedicated space for those really important photos and use Simplify Photo for those that are not as important but would nonetheless like to have access to just in case.
Simplify Photo is available for 99 cents on the iTunes App Store, while the required desktop client (available for Mac OS X, Windows, and Linux) is available as a free download at the Simplify Media site. The desktop app allows you to not only specify which iPhoto albums and events to sync, but the people as well -- via integration with the app's "Faces" facial detection feature. And if you're not exactly sure which album or event a photo is stored, you can use the app's search feature, which searches your photos' tags, titles and comments.
But the standout feature of Simplify Photo is its geolocation support. Like iPhoto '09's places feature, Simplify Photo displays a map with various dropped pins; and tapping on the pins will display the photos taken in the vicinity.
If a picture can say a thousand words, then Simplify Photo's desktop syncing capabilities have the potential to make your iPhone speechlessly filled with photos.
