Read full descriptionHide full description
Not another to-do app. ParaCortex is for anyone who's stared at a task list and felt more stuck than when they started. Whether you have ADHD, suspect you might, or just find your brain works better with the right support β this was built for you. We don't do "Overdue." We do Roll Forward. Tasks you didn't get to yesterday quietly carry forward to today. The ones you didn't finish this morning are still there this evening. No deadline labels. No shame spiral. Just your list, ready when you are. CAPTURE IN SECONDS Tap the mic and speak it. ParaCortex transcribes and saves your task before the thought disappears. No typing required. BREAK IT DOWN "Reply to emails" isn't a task. It's a wall. ParaCortex uses AI to break any goal into bite-sized micro-wins β 5-minute steps you can actually start. MATCH YOUR ENERGY Every task has an Energy Cost: Low, Medium, or High. Each day, ParaCortex checks in β how's your energy right now? β and surfaces the one task that fits. No scrolling through a long list. Just the right thing for right now. FOCUS MODE When you're ready to begin, tap into a dedicated Focus screen. A circular countdown ring makes time feel tangible, not just countable. Pair it with built-in ambient audio β brown noise, rain, lo-fi β to create the conditions your brain actually needs to stay on task. YOU'RE NOT ALONE Body Doubling is the quiet magic of knowing others are working too. ParaCortex shows a live count of focusers in the room β no chat, no pressure, just presence. STAY ON TASK, EVEN WHEN YOU LEAVE Your current micro-win stays visible on your Home Screen, Lock Screen, and Dynamic Island. Out of sight shouldn't mean out of mind. GENTLE REMINDERS, NOT ALARMS Nudges arrive at natural transitions in your day β not as deadline warnings, but as open invitations to begin. CELEBRATE FOR REAL Every secured win triggers a full-screen celebration β confetti, balloons, fireworks, and more. Your brain deserves the dopamine hit. ParaCortex isn't about doing more. It's about feeling less stuck β one small win at a time.

Lockn is a focus planner built for real days, not perfect ones. Todo list keeps growing? Getting distracted by your phone? Lockn gives you a stronger system. Add your tasks, set your work hours, choose the apps you want blocked. In under a second, Lockn turns your day into a focused schedule with sessions, calculated breaks, meals, and commitments already built in. WHY LOCKN WORKS TIME BLOCK YOUR DAY IN ONE CLICK Add tasks once and let Lockn build a realistic daily plan around your work window. It decides what fits, what comes next, and where each block should go, so you are not dragging calendar blocks around every morning. COMMITMENT BLOCKS Class, work meetings, gym, appointments, lectures, commutes, and other fixed parts of your day can be saved as commitment blocks. Lockn treats them as protected time and plans your focus sessions around them, not over them. NEVER BURN OUT AGAIN - AUTO BREAKS Every focus block can include a break automatically. Lockn calculates break time from the length and intensity of the work, so a short light task gets a smaller reset while deeper work earns more recovery. MEAL-AWARE PLANNING Your day is not one endless work window. Lockn can account for breakfast, lunch, and dinner, keeping focus sessions away from meal times so the plan fits real life. It even schedules your work day such that a longer task will come before your meal so your meal doubles as a break! REAL APP BLOCKING During a focus session, Lockn can block distracting apps and websites. Choose what gets blocked, then start your session and stay with the work. Your phone doesn't need to be completely un-usable when working. Once the session is over, everything gets unblocked automatically. ADAPTIVE RESCHEDULING Real life happens. If you miss a block or fall behind, Lockn helps move the work into the next available slot while respecting meals and commitment blocks, instead of making you rebuild the whole day. FINISH EARLY? INSTANT RESTRUCTURING Complete a block ahead of schedule? Lockn restructures the rest of your day, finding the most efficient way to organise the remaining tasks given the extra time all while respecting fixed blocks. WE DONβT LOCK YOU IN OUR APP Keep an eye on your session at all times. Live Activities show your countdown on the Lock Screen and Dynamic Island while you stay focused. You can get work done on your phone too, we get that. FRIENDS FOR ACCOUNTABILITY See when friends are locked in and let them see when you are working too. No noisy feed, no performance pressure, just quiet presence that makes it easier to start. STREAKS AND HEATMAPS Track completed sessions, weekly progress, streaks, and your recent focus history so each day of effort builds into something visible. Streaks are session based not by day; not everyday is a work day! A SCHEDULE BUILT FOR YOU Lockn can account for whether you prefer hard work in the morning or later in the day, placing deeper tasks when your brain is more ready for them. Lockn is for students, creators, founders, and knowledge workers who have tried todo lists, Pomodoro timers, habit trackers, calendars, and Notion setups, but still struggle to actually start and follow through. Plan the day. Win the day. Repeat. View full terms of use here: https://thelockn.com/privacy
