Learning on your phone

STEMpump.org works on any phone browser, and lessons are laid out for small screens.
- At the bottom of every lesson, a toolbar has previous and next buttons. They move across chapters too, and next marks the lesson complete.
- The middle of the toolbar shows where you are, like "Chapter 2 · 3 of 6". Tap it to open the whole course outline and jump anywhere.
- Tap the magnifying glass at the top of the page to search.
Your progress on your phone's browser is separate from your computer's. See Where is my progress saved?
On an iPhone or iPad, the STEMpump App adds downloads, widgets and more.
