Happily, you pick exactly what is synced on each device--thumbnails, previews, or the originals. For example, you may sync thumbnails or previews to iOS devices and originals to computers and external hard drives (if you shoot in raw format and choose to sync originals to an iOS device, a scaled-down DNG is sent instead of the raw version). You can also limit syncing to a subset of photos, say, only those that are 5-star rated, color-coded or that have certain keywords.
Three shields at upper right of the interface show protection status: the first shield indicates that you have the originals on the device you're currently using. The second shield indicates that you have the originals on another local copy, and the third shield indicates that you have the originals on a remote device at an offsite location of your designation (perhaps an external drive kept elsewhere that you periodically plug in).
While Mylio includes cloud storage, it's only used for remote syncing (think "transfer highway"), which is incredibly handy when traveling or shooting on location (imagine syncing a subset of photos onto an assistant's remote device!).
Organizing, editing, and sharing
Mylio lets you arrange photos into albums, lightboxes, tag them with people and location info (think facial recognition and geotagging), apply a flag, 5-star rating system, and color-coded labels--all of which you can use to find photos later on. A handy Auto-Advance switch lets you move to the next photo once you tag or rate the current one. Built atop a gaming GPU, browsing thousands of photos in Mylio is smoking fast. You can view photos by their import folders, albums you've made, by date visually on a calendar (nice!), by people or location tags, your last import or search.
Editing in Mylio on your Mac or iPad is easy and nondestructive, but you can't edit on an iPhone. You'll find a histogram, as well as auto-enhance, crop, and red-eye tools, a before/after comparison button (nice!), temperature and tint sliders for adjusting white balance along with sliders for exposure, contrast, highlights, shadows, whites, blacks, clarity, sharpen, vibrance, and saturation. You can convert photos from color to black-and-white, copy edits from one photo to others, change date/time, edit metadata, and revert to your original. When you import photos from Lightroom, the edits that Mylio supports can travel back and forth.
Unfortunately, as of this writing, there's no way to adjust parts of a photo (say, to darken just the sky or remove an object) or create projects such as photo books, print templates or web galleries. That said, you can send photos from Mylio to Lightroom and the company states aggressive plans for future versions. Incredibly, anything you do in Mylio is instantly synced, and thus reflected, on all devices. You can also share photos via email, Facebook, Flickr, export them (say, to create projects with in other apps) and print straight from Mylio (expect Twitter support soon).
