Read full descriptionHide full description
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
Sammy ADHD Task Support
Read full descriptionHide full description
Most task apps hand you a long list and let you stare at it. Sammy hands you one card. Swipe right to start it, swipe left to skip it. That's the whole thing. WHY ONE CARD INSTEAD OF A LIST A to-do list asks you to do three things at once: choose what matters, rank it against everything else, and start. If you stall at the starting line, that isn't one wall, it's three. A single card collapses all of it into one binary decision: this task, yes or no. That's a decision size a stalled brain can actually make. HOW IT WORKS - One task at a time, never a wall of to-dos - Swipe right: a timer starts, you begin - Swipe left: skipped, no penalty, no judgment - Sammy the squirrel collects a nut for every task you finish, visible progress right now instead of some abstract payoff later - Decks for chores, admin, self-care, getting out the door, and days where brushing your teeth is the whole win NO STREAKS, NO GUILT Sammy doesn't count how many days in a row you've kept it up. There's nothing to break. Anyone who has fought procrastination knows the spiral: miss one day, and the app becomes one more thing accusing you. Sammy only counts upward. WHO IT'S FOR People with ADHD, executive dysfunction, anxiety, or just an ordinary bad day. Adults, teens, and kids, with content curated per age group. HONEST ABOUT THE SCIENCE There's a screen inside the app that explains the actual mechanism behind each feature: why task paralysis is better understood as an activation failure than a motivation problem, why decision fatigue costs more for ADHD brains, and what the nut counter is really standing in for. It's equally explicit about where the evidence is thin: there is no controlled trial of Sammy's specific implementation. That's exactly why there's a free trial instead of a "trust us" pitch. PREMIUM - Unlimited custom decks and cards - Mood check-in: tasks adapt to your actual energy, not the energy you wish for - Full win log - Recurring schedules - Two more companions: Eddy the elephant and Tammy the turtle - Offline decks Sammy is not a medical device and does not replace diagnosis, advice, or treatment.
