iOS: You have a lot of options for journal and photography apps, but Bokeh is an app that keeps things decidedly simple. With it, you can upload full resolution photos, add notes, and keep a simple journal either privately publicly. You can then search through those pictures with a fantastic calendar view.
The web app calendar view is what sets Bokeh apart from everything else. It's simple, but it works really well. Snap a picture, then add a note, and you're done. The photos upload to Bokeh's servers. You can set your images to public or private, but there's not really a social element here; it's mostly about creating a simple place to drop memories.
