Formulas & Forces Lab is an offline study portfolio for 6th grade Math and Physics. Instead of focusing on scores, students produce study artifacts: Explain-It cards, Worked-Solution rewrites, Mistake Pattern cards, session summaries, and revision plans. Practice and review prompts are used to generate reflections and structured write-ups that stay on-device. A built-in portfolio exporter creates a shareable PDF notebook from recent artifacts and active revision plans. No accounts, no analytics, and no network accessβeverything is bundled locally and stored privately on the device.
