Neural Network Academy
iOS Universel / Education
Neural Network Academy makes artificial intelligence hands-on, approachable, and genuinely fun.
Whether you're a student, a curious adult, or a developer new to machine learning, this app
guides you from "what even is a neuron?" to training real AI on your own photos — no experience
needed.
-- LESSONS --
Five bite-sized lessons cover the ideas behind every modern AI system:
• What is a Neuron? - drag sliders and watch a single neuron compute in real time
• Weights & Bias - see exactly how small number changes shift a network's output
• Activation Functions - explore sigmoid and ReLU on live interactive graphs
• How Networks Learn - follow a forward pass step by step with animated signal flow
• Backpropagation - understand the algorithm behind every AI you've ever used
Each lesson ends with a quiz that locks in what you've learned and earns XP to unlock
the next tool.
-- PLAYGROUND --
Train a real neural network on classic logic problems: XOR, AND, and OR. Watch the live loss
curve fall as your network finds the pattern. Adjust layer count, neuron count, and learning
rate - then hit Train and see the math work.
-- NETWORK BUILDER --
Design your own architecture from scratch. Add layers, set neuron counts, and watch the signal
flow forward through your custom network before training begins.
-- HOT DOG LAB --
Draw examples directly on a pixel canvas, label them, and train a classifier on your own
drawings. Works with any two categories you choose - a playful introduction to image
classification.
-- PHOTO CLASSIFIER --
The most powerful tool in the app. Pick two categories, add photos from your library, tap
Train, and watch a real model learn to tell them apart. Test it instantly with any new photo.
-- BUILT FOR LEARNING --
• XP & level system keeps you motivated and on track
• Lessons unlock progressively - concepts build on each other naturally
• Every idea has an interactive demo, not just a wall of text
• Live training animations show loss dropping in real time
• Clean native iOS design - no ads, no subscriptions, no account needed
Neural Network Academy is for anyone who has ever wondered how AI actually works. Not just
how to use it - how it thinks.
