How We're Different

🔬

Science-Based Criteria

We evaluate against the Invariant methodology — rigorous learning science principles, not engagement metrics.

✓

Binary Verdicts

No confusing star ratings. Either an app meets the standard for effective teaching, or it doesn't.

🤖

Agent-Friendly

Structured data and API access so AI assistants can recommend apps that actually work.
