Dice 3D is a free dice roller app for Android that offers realistic physics and high-quality 3D graphics. The app has up to 120 dice with different colors on the screen, and users can throw all dice or roll each die individually. The dice size is adjustable, and the app uses true physics for realistic rolling. The 3D animation is also true, with custom shaders and highly optimized OpenGL ES2.0 graphics.

One of the unique features of Dice 3D is the ability to lock selected dice in place, making it perfect for games like Yahtzee. The app also has tilt/gravity functions, sound and vibration feedback, and a roll history. The roll methods include repeatedly tapping the screen, tilting/shaking the phone, and dragging/flicking the dice individually.

The app uses the VIBRATE permission to provide vibration feedback when dice collide, and INTERNET and ACCESS_NETWORK_STATE permissions to fetch adverts from the internet. The WRITE_EXTERNAL_STORAGE permission allows users to move the app to external storage. Please note that Dice 3D is ad-supported.

Overall, Dice 3D is a great app for anyone looking for a customizable and realistic dice rolling experience. For any issues or suggestions, users can email the developer directly.
