The hardest part of learning CNNs isn't the math — it's not being able to picture what's actually happening. What exactly happens when the kernel slides across? Why does the feature map look like that? Why does adding one more layer help? Textbooks answer with symbols. NeuroVis shows you. Draw a digit with your finger, and a real CNN classifies it layer by layer in front of you — input tensor, convolution feature maps, activation, max pooling, and the softmax probability for each of the ten digits. Every stroke recomputes the entire chain instantly. Tap any feature map and the kernel sweeps across the input cell by cell, so you can see exactly where each output number comes from. Step through it, pause it, or just read the values off the grid. Wondering what those numbers inside the kernel actually do? Change one and watch the feature map follow. Wondering whether another layer matters? Add it and find out on the spot. And at the end, it tells you why it picked that digit and not another one — which strokes count as evidence, and which argue against it. This isn't a canned animation. It's a real model running on your phone. Fully offline, no data collected. For: students learning deep learning, engineers building intuition, and anyone who has read the formulas but still has no mental picture.

Verdict

The call

The clearest difference is in-app purchases: NeuroVis at none against Mechanical Formula's 1. NeuroVis also leads on update cadence (every 11 days vs every 4 months). Mechanical Formula's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price and ads there is nothing between them.
