The developers, Peak Systems, have recently released Diptic version 6, which is by far the biggest update ever. Tons new features including:

• 100+ new layouts (there are now 165 total layouts — more than any other photo-collaging app). In addition to the 165 free layouts, there are additional layouts available as in-app purchases.
• Text! This free feature lets you add text captions to really “tell the story.” Adjust the font, size, color and placement.
• Background textures (polka dots, fur, stripes, etc.), which are available as in-app purchases ($0.99).
• Postcards! Send Diptics through postal mail to your loved ones. Powered by our friends at Sincerely.
• iPad love. Diptic is now optimized for the iPad in landscape mode and has a special interface just for this use.
• Inner frame lines are now composed of joints, which you can move to completely customize your Diptics. With joints, you can create curved lines and completely customize your layouts.
• Photo swap! You can now swap photos between frames.
• Improved photo picker: Choose from selecting all of your photos at once (a huge time saver!) or individually.
• Modified UI and improved in-app help.

This update is available as a free download and Diptic is available for $0.99. You can download it by clicking here. Enjoy!
