What?
When uploading an image to Raken from your device, you can now search by date and subject, thanks to a recent Apple update. This feature is currently available only on the iOS version of the Raken app.
How?
When using Raken to search for photos on your device you will now see a bit different interface. At the top of the display, you will see a search box where you can type in anything from a date to the subject of the photo (ex. If you are looking for a picture of a dog you could type in dog).
