Apparently Lumific has the time and the tools for the job. Lumific is a free photo gallery app for Androids that will automatically edit and organize your photos.
It can group similar photos together by identifying the date and location that they were shot. You get a collection from your August vacation, another from the October wedding you attended and one more from Christmas.
For more details, check out the video below, visit the Lumific website or the app page in the Google Play Store. You can also follow @Lumific on Twitter.
