Denny’s Maze
I built the product I wanted first: a quiet maze-book experience with no ads, no timers, and no flashing reward loops. It is the app I can confidently give to my own child.
Independent app lab · built by a mom
Harmless Apps finds and builds low-stimulation, educational digital products that respect a child’s attention—and a parent’s trust.
01 / Mission
The App Store is full of products labeled educational. That does not tell you whether an app is noisy, manipulative, shallow, impossible to use offline, or genuinely useful for a young child.
I test those things directly, using the same question I ask as a parent: would I feel comfortable giving this to my own child?

What does the child actually have to think about or do?
Does the child make meaningful choices, or mostly follow prompts?
Does the experience develop, or repeat the same shallow interaction?
Could the learning matter beyond this one app?
Why this exists
I spent 13 years building apps designed to hold attention. After becoming a mom, I wanted to use those skills differently. Denny’s Maze came first. Then I started testing the rest of the market—with the same standards I use for my own product and my own child.
