In a world designed to capture our attention, it may feel like a constant battle to focus on your work. Do This First is a focus tool built on a simple, powerful idea: your phone should help you achieve your goals, not distract you from them. The concept is simple. You decide on the essential tasks for your day and start a Focus Session. While the session is active, the apps you've marked as distracting are temporarily blocked. The only way to get them back is to complete your list. It’s an unbelievably easy way to finish things that matter. Prioritize The Important Instead of a never-ending to-do list, create a short list of what you need to accomplish right away. Prioritizing helps you stick with your commitment and kills procrastination. Create a Distraction-Free Space You have complete control over which apps and websites are off-limits during a session. By removing the temptation for a "quick check" of social media or news, you give yourself the freedom to concentrate fully on your work. Keep Your Tools Accessible Productivity isn't about blocking everything. Our Allowlist feature ensures your essential tools—like a calculator for homework, music for ambiance, or a note-taking app—remain available while everything else is shielded. See Your Discipline Grow Your effort deserves to be recognized. The Stats tab visualizes your progress, tracking your total sessions, average focus time, and helping you build motivational streaks. It’s a clear and satisfying look at how your habits are improving over time. Build Effortless Routines Use Scheduled Starts to automate your most important work blocks. Set up your "Weekday Study Period" or "Morning Writing Hour" once, and let the app automatically create your focused environment when you need it most. Get Smarter Reminders Enable Smart Notifications, and the app will learn your typical work patterns. It will send a timely, gentle nudge when it senses a good opportunity for you to start a productive session. Your goals are important. Download Do This First, and let's start making real progress on them, together.
