Most study apps try to plan out everything. PrepFlex doesn't. Tell us how much time you've got, even if it's just 20 minutes between classes, and what you need to cover. PrepFlex figures out what's actually worth studying in that time and builds a plan around it. Sometimes that's every topic on your list. Sometimes it's just the one or two that matter most. Either way, you'll always see exactly what made the cut and why. How it works: • Enter the time you have right now • Add what you need to study • Rate your confidence and how much each topic counts • Get a plan built for the time you actually have Get the most out of the time you have. No sign-ins, no distractions, no accounts, no ads, just a plan, built fast, for whatever time you've got. Built by a student who got tired of study apps that just don't get it.
