STEM kits as a screen-time alternative

Plenty of STEM kits market themselves as screen-free. It is worth being precise about what that means, because several of the best options in this category use an app - and the distinction that matters is not whether a screen is involved but what the screen is doing.

Passive screens vs instructional screens

A tablet game is the activity. An instruction app is a means to an activity happening off the screen - the child looks at it, picks up a gear, looks back. Those are different behaviours, and treating them as the same thing leads parents to reject good products.

ibrick and MEL Science both use apps. CrunchLabs uses video. KiwiCo and Little Passports are the genuinely paper-based options. If your objection is to screens in principle, that last group is your shortlist. If your objection is to passive consumption, the calculation is different.

What actually competes with a tablet

In practice, only two things reliably pull a child away from passive screens: a payoff that is physical, and a loop that resets. A build that ends with a motor running provides the first. New content arriving before interest fades provides the second. Kits missing either tend to lose the competition, regardless of how good the science is.
