Neural Network
Learning and using neural networks in an intuitive and natural way. Open the black box with simplified datasets and full visualization — then build models by dragging your fingers.
Free to download; Pro features are available through an optional subscription. Also available on Google Play and macOS.
Interactive tutorials
A large number of charts and interactive components make learning more intuitive — key concepts and dynamics are shown with charts and animations: activations, regularizations, loss functions, classifications, Embedding, CNN1d, CNN2d, RNN and more.
Visualized neural network lab
- Open the black box of neural networks with simplified datasets and full visualization.
- Variety of datasets: 2D and 3D, both regression and classification — get the dataset with just a tap.
- Do experiments anytime, anywhere — the whole lab fits in your pocket.
- Values panel: see every number of a sample layer by layer — inputs, each neuron's b/z/a, every edge weight and its product, output and loss — copy it or export as CSV.
Learn with mission-like gaming
In the missions you run into many key concepts of neural networks, complete the challenges, and acquire a deep understanding — learning by doing rather than by reading.
Visualized deep learning models
Learn the most classic models in an intuitive way that has never been seen before, and quickly master cutting-edge technology. Through modular diagrams, understand how data changes from input to output and how it changes at each step. There are detailed documents for each module — and even reference papers, source codes and animations.
Visual model editor
- Quickly build a model by dragging your fingers. What you see is what you get.
- Real-time calculation and display of the output of each step — construction has never been so intuitive.
- Real-time display of various errors, including parameter/input type and value compatibility — abandoning inefficient debugging.
- Export PyTorch-style code from the model you built.
Details
- Three platforms — iOS, Android and macOS from one codebase.
- Ten languages — English, French, German, Italian, Japanese, Korean, Russian, Spanish, Simplified and Traditional Chinese.
- On the App Store since 2020, actively updated — v4.22.0 shipped dark mode and the Values panel in October 2026.
- Rated 4.7 out of 5 from 141 ratings.
