Formulas & Forces Lab vs IdeaRebuild

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 access—everything is bundled locally and stored privately on the device.

IdeaRebuild helps you inspect one idea at a time. Break it into parts, mark where it fails, choose a repair strategy, rewrite it, and save a clear Rebuild Record for review.
