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.
Reflow

Your day never goes exactly to plan. Reflow is the first planner that expects that. Most planners hand you a perfect schedule at 8am and guilt by noon. Miss one block and the whole day collapses — so you stop opening the app. Reflow works the other way: when life shifts, your plan shifts with it. One tap, and you're back on track. THE TIMELINE THAT HEALS ITSELF • Running 20 minutes late? Reflow previews how the rest of your day can flex — you confirm with one tap. • Locked blocks (meetings, appointments, school pickup) never move. Ever. • Flexible blocks reshuffle around them automatically. • See the new plan as ghost blocks before anything changes. You stay in control. SPEAK YOUR PLAN • Say it like you'd say it to a friend: "Gym at 5, then groceries, dinner with Alex at 8." • Reflow turns it into timeline blocks as drafts you confirm — nothing is ever saved without your OK. • Voice is processed entirely on your device. Audio never leaves your phone. REMINDERS WITHOUT GUILT • Gentle escalation that works with your brain, not against it — a nudge, then a firmer one, only if you need it. • Missed something? No red badges, no streaks broken, no shame. Reflow simply asks: reinsert it today, move it to tomorrow, or let it go. • Quiet hours mean your evenings stay yours. MADE FOR ADHD BRAINS • Time blindness support: your day as one visual timeline, with a live "now" line. • A Live Activity keeps your current block on the Lock Screen and in the Dynamic Island. • Unlimited colors, 400+ symbols, and every emoji to make blocks unmistakably yours. • Calm, dark-first design. No clutter, no dashboards, no productivity theater. YOUR DATA STAYS YOURS • Sign in with Apple protects account and subscription access. Your plans live on your device, synced privately through your own iCloud. • No ads. No data selling. No tracking. REFLOW PRO Your first two distinct planning days are free. After that, Reflow offers a 14-day subscription trial — $9.99/month or $49.99/year. Subscriptions renew automatically and can be cancelled anytime in Settings. Payment is charged to your Apple ID account. Trial eligibility is determined by Apple. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://devbiok.github.io/reflow-site/privacy.html Reflow was built with one belief: you were never the problem — rigid plans were. Welcome to the planner that finally flexes.

Verdict
The clearest difference is in-app purchases: PrepFlex at none against Reflow's 2. PrepFlex also leads on iOS requirement (15.6 vs 17.0). Reflow's advantage is update cadence (every 5 days vs every 10 months). On price, ads and device support there is nothing between them.
