ivy

Ivy is an elegant and smart photo organizer that automatically collates your photo life into events, from your device and your cloud storage.

Ivy collects your photos from all the popular social / image hosting services — Dropbox / Picasa / Google Drive / SkyDrive / Flickr / Instagram / Box.net / OneDrive and local device — and organizes them into one cohesive timeline. Collected photos are automatically organized into events based on the time they were taken. Your artistically collaged photos can be selectively shared to any person or service you'd like.

Ivy is both free of cost and free of ads.
