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.

About

Vibelist

Most todo apps show you everything at once — including all the things you can't actually start yet. Vibelist is different: you tell it what depends on what, and it shows you only the tasks that are ready right now. Everything else waits quietly until its turn comes. Chain your tasks. "Book flights" can't happen before "Research destinations." In Vibelist, you link them once — and "Book flights" stays hidden until research is done, then appears by itself, exactly when it becomes possible. No more scrolling past blocked tasks, no more mental filtering. See your work as a map. The graph view lays your projects out as flowing chains: what's active now, what's coming next, and how it all connects. Pinch, pan, and tap a task to edit it. Completed work drifts into the past, where every project keeps a clean, chronological record — read it top to bottom, left to right, and you can replay exactly how you got here. Plan your day with intent. Flag the tasks you want to tackle today. As you complete work, follow-up tasks that become ready take their place automatically — your plan advances itself. Projects with personality. Group tasks into projects, give each its own color, reorder and rename them freely. Colors adapt to light and dark mode so everything stays readable. Your data stays yours. Automatic iCloud backup and sync across your devices — no account, no login, no tracking. Export your entire list as readable JSON anytime, and import it back whenever you want. Widgets keep your ready tasks on your home screen. Vibelist is for anyone whose work comes in steps: students, parents, entrepreneurs, people with ADHD — anyone who's ever written "(after X is done)" next to a todo. Stop managing your list. Just do what's up now.
