Jeez, surprised that this wasn't on Product Hunt already. It's been out for some time now. Brilliant little app. It's a one trick pony, but what a pony it is. Essential for photographers and - even more so - iPhotographers like myself. Well-executed. Love it.
Lumy seems like a nifty product. Not part of the target group so can't say if it's useful for photography, but it's definitely nicely designed. Also love that it has a Watch app.
