Flickr for iOS has been around for quite a while now. But it has just gotten the Auto Upload feature. Up until now, users had to upload photos from their iPhone manually. iOS 7 users now get to automatically save their photos to Flickr. They are stored privately until you are ready to share them.
Flickr for iOS also offers auto-straightening. As the name suggests, this tool straightens your pictures for you. It is useful when your photos are just a bit off. The update is available to download from the App Store.
Speaking of iPhone apps, Logocal happens to be a pretty neat calendar app for iOS. It turns the events you have entered into an agenda. You will be able to keep up with tasks for today, tomorrow, and the future easily.
You can use all the calendar accounts you already use on your phone. Calendars can be filtered to show events that interest you. Users can search through their events by title, location, and notes. VoiceOver is supported. Logacal requires iOS 7 to work. It sets you back $4.99 at the time of this writing.
