Prolog

Read full description

Unlike other screen time, focus, or productivity apps, Prolog delays access to applications by showing you your dreams and goals instead of completely blocking them. Have you ever tried using focus and screen time apps, but they didn’t always work? It only takes one relapse to fall right back into old habits, right? BENEFITS Stay focused on achieving your goals and dreams quickly. Save more than an hour a day effortlessly. Improve your physical and mental health in just 20 minutes. Increase your productivity at work or in your studies. Live without regrets. Prolog is the solution to get the life you want: Prolog solves our unhealthy relationship with our phones by making social media less important and putting your top priorities first so you don’t forget to work on your goals and dreams, and to actually achieve them. 92% of people fail to achieve their goals, and this is mainly due to two factors, both linked to social media. The first is that our brains are overloaded with information, leaving us unclear on what we really want. Social media makes this worse—many people do things not for themselves but because they’ve seen others doing it. They end up not liking it, quit, and the cycle repeats. The second reason is that social media distracts us; instead of working on ourselves to become better and achieve our goals and dreams, we find it easier to scroll for hours, wasting the most valuable thing in life: your time. But with Prolog, every time you open one of your favorite apps like YouTube, Instagram, TikTok, and others, it will first show you your goals and why you need to achieve them. This gives you time to think about whether it’s really worth going into the app. And if you still decide to use the app after seeing your goal, you can. And if you say, “I don’t know what my goals are,” don’t worry, we’ll assist you from the very beginning, from setting your goals to achieving them. You only have one life—avoid regrets and become the person you truly want to be. FEATURES Define, edit, and improve your goals with our help. Anti-Distraction View: Activates a page with your goals every time you launch one of your favorite apps (YouTube, Instagram, Facebook, Tinder, etc.). Don’t get stuck in the social media spiral. Notifications: Set a timer for how long you want to stay on an app, and once it’s over, the app will close, ensuring you don’t spend hours scrolling. Prolog is based on something that already works; we just made it better. It’s called 'one sec'. The effectiveness of 'one sec' was confirmed in a scientific study with the Max Planck Institute and the University of Heidelberg: app usage decreased by an average of 57% in the long term! "Prolog" uses shortcut automation to trigger an animation that shows your goals every time you open one of the configured apps (Instagram, Twitter, YouTube...). Thanks to this, you’ll think twice before opening social media and consider if it’s better to work on your goals instead. Your Privacy We do not save any of your data. We don’t have a database, and you don’t even need an email to use the app. All your information stays on your phone. You are the sole owner of your data with us. Unlike most companies, we do not sell any of your information. This app helps you reflect on your actions, thoughts, and feelings, breaking harmful social media habits through mindfulness.
