blocos is the ultimate daily planner & time blocking app built to make you productive and organized! This app approaches time management and daily organization in an innovative way, inspired by a Wait But Why article. It's a perfect ADHD planner and calendar for ADHD people! It has a daily schedule planner based on the 144 blocks daily calendar that will make it much easier to time block your habits. THE 144 BLOCKS CALENDAR It's hard to plan your day as just one big block of 24 hours. You overestimate how productive you can be. This innovative calendar is simple: it breaks down this big 24-hour block into 10-minute pieces, so you can better visualize your time and properly timebox your habits, tasks, and activities, all with time blocking. 144 10-minute blocks equal 1440 minutes or 24 hours. If you sleep 7-8 hours a day, you'll have 100 small blocks to keep track of. If you work for 8 hours, well, you'll have 52 blocks left. Using the app you'll see how little time you have. However, you'll also be able to track it much more efficiently, building a routine with daily habits that best fit your lifestyle. How will you use the next block? Start habit tracking and stop procrastination with some great features: - Track as many activities and habits as you need. You can journal everything! - A blocks-based visualization of every single day: time block your way to your goals and end procrastination! - Daily reminders in the day planner: after allocating an activity, you'll receive a notification 10 minutes before it starts! - The perfect productive habit tracker: you can easily use it as a daily habit tracker to make sure you build good habits or stop bad habits - Journal and Planner: It's a passion planner, so you can always have time for your passions, but it's also a school planner/work planner that'll help you focus on what you have to do - Statistics and charts make this the ultimate goal tracker and activity tracker - Ad-free: we hate ads and don’t want to bother our users You can use this app in two ways: 1. A precise journal and time planner: strictly planning every day, keeping track of each block 2. A great weekly planner: pick a couple of activities to track. You can keep track of just some of them, and visualize the weekly calendar with the blocks filled Both ways will help you live more productive and happier days! However, it's much more than a time-blocking app! BEYOND TIME BLOCK: ONE OF THE BEST ORGANIZATION APPS To build a daily routine, be productive and organized, just offering an innovative daily calendar isn't enough. This app goes beyond being a habit tracking app or one of the best goal tracker apps: we aim to be one of the top productivity apps, no matter your time management skills! The activities are the basis of everything. Inside them, you have a bunch of features that make it one of the best life planner, daily planner free & organization apps: ◦ A full task manager: organize your to-do-list for each activity, create a daily checklist or daily reminders ◦ Focus timer: open the Pomodoro timer to apply the Pomodoro technique, set how long are the focus rounds, short breaks, and long breaks (the classic 25-10-30 technique or custom like 60 30 30) ◦ Keep a daily diary or save important notes: use the Notes widget inside the activity to create notes like a diary or just use it as a note block. ◦ You can keep a diary for each relevant activity or just focus on the deep work! Very soon there'll be a Group Pomodoro feature that will allow you to track time with your team or just keep focus with other people that are working or studying! A team Pomodoro (or team time tracker, team timer) like you've never seen before!

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.
