Totality by Big Kid Science, developed by Germinate LLC, is an iPhone educational app designed to guide observers and educators through solar eclipse planning and learning. It provides interactive, map-driven eclipse information and localized viewing predictions to prepare users for specific events. The app bundles educational content and safety guidance alongside tools that help find and reach optimal viewing locations. It targets students, classroom teachers, amateur astronomers, and families preparing for field observation or in-class activities.

Planning and navigation meet field needs for eclipse chasers

Totality supplies calculation-backed maps and on-device location tools for precise field planning. Its interactive maps display the path of totality and the app's dataset covers future events throughThe GPS-based current-location tool reports exact local circumstances and a detailed circumstances table lists start, peak, and end times for any tapped point. Navigation and routing features help users reach a chosen viewing site, and the app uses Xavier Jubier's eclipse calculation code.

Classroom instruction and safety materials fit lesson planning

The app's Learn screen presents eclipse science explanations, safety guidance, and downloadable classroom activities teachers can adapt for lessons. An integrated shop offers ISO-compliant eclipse glasses and science books to support hands-on exercises, and the project is maintained as a public service by the American Astronomical Society. Language selection adjusts automatically to the device, supporting English, Spanish, French, and Portuguese for multilingual classrooms.

Accessible on mobile devices but not structured as a course platform

Totality runs on iPhone and tablet hardware as well as Android devices, so field teams and classrooms can use the same resource across device types. The feature set centers on event calculation, maps, and teaching materials rather than learner progress dashboards or built-in assessment. Educators who require graded tracking or completion reports should combine the app with an external classroom management tool for assessment and record keeping.

Totality is a practical companion for educators planning hands-on eclipse lessons

Totality is a focused option for educators and observers who need reliable, event-centered guidance and classroom-ready materials; it supports pre-event instruction and on-site coordination. Educators requiring integrated assessment or course-style tracking should prepare to use a separate classroom management system. For practical eclipse preparation and public outreach, the app supplies targeted resources that support real-world observation and lesson delivery.
