This app allows you to train and test a 3-layer neural net with handwritten digits (0...9).

For this, you may use the embedded MNIST data base including 40.000 handwritten digits. Furthermore, you can teach the net with your own handwriting by using your smartphone camera or writing on the screen with your finger.

The app is based on and inspired by the example of Tariq Rashid given in his book "Make Your Own Neural Network" . The app source code is on GitHub.
