TerraChron 9 is an offline Grade 9 History & Geography Study Studio. Each session ends with a saved Notebook artifact in the learner’s own words (with v1/v2 revisions) and a calm Daily Passport check-in. Use the Atlas for short theory, key terms, and text-only timelines or place/climate facts, then complete guided Studio Runs with self-check and reflection. Review Lab builds focus sets from local mix-ups and saves Revision Cards for later review.
ReasonPad

ReasonPad is an elementary reasoning tool for Grades 1–6. Each session is short and focused: students complete one reasoning pad, write a one-sentence explanation, and lock it as a read-only card. The app avoids accounts, tracking, ads, and web content so students stay in a simple, distraction-free workspace.
