Orbit turns AP studying into something you'll actually open. Questions come one at a time, full screen, and you swipe up for the next one. Tap an answer to aim, tap again to lock it in, and every question explains the right answer so you learn from misses as well as hits. Right answers in a row build a streak, and streaks multiply your XP. Three in a row doubles it, and it keeps climbing from there. XP levels you up through the ranks across all of your classes. Orbit quietly tracks every skill you practice. The Progress screen shows how you're doing in each unit and which skills keep tripping you up, and a weak-spot run pulls together the questions you've missed plus others from those same skills. Clear them and you're back to exploring the whole course. Set your exam date and Orbit lays out a plan that counts down to test day, with a unit to focus on and how many questions a day will get you there. You can also drill a single unit or mix everything together. Orbit covers 20 AP courses, including Biology, Chemistry, Physics 1 and 2, Calculus AB and BC, Precalculus, Statistics, Environmental Science, Psychology, Human Geography, U.S. History, World History, European History, U.S. Government, Comparative Government, Macroeconomics, Microeconomics, Computer Science A, and Computer Science Principles. Pick only the ones you're taking. No account needed. If you want your progress backed up to a new phone, you can save it with just your email, and delete your account anytime from the Progress screen.
