There's a growing need for handy UI freebies and resources dedicated to iPhone app design. To fill this gap I've created DigiMag - a free iPhone app UI designed in Photoshop. The interface has been created specifically for iOS 8 using the new iPhone 6 screen dimensions.
Feel free to download a copy of this PSD and use for any design project. The whole interface is organized using guides and layer groups in Photoshop. It's easy to work with and perfect for learning how to design your own mobile UI from scratch.
