In Japan, getting your nails done is a big part of fashion for women of all ages. But it can be tricky to find new designs on a regular basis. But there is an iPhone app called Nailbook that many women are turning to for nail design inspirations.
Nailbook has been downloaded over 500,000 times as of July 21st of this year (see chart below). There are over 250,000 nail designs in the app with about 700 new photos added everyday. The application is used by people both here in Japan as well as overseas. In total, there are Nailbook users from more than 102 countries.
You can follow other users you like, or favorite nail design photos for future reference. You can also upload recent nail designs of your own. Some professional nail artists even do this to promote their work.
Finding the great designs on a platform like this is easy, as photos can be searched according to situation (i.e. Is it for work, or for an upcoming date?). A ranking feature showing the most popular and kawaii designs of the past week helps as well.
