“Random Reminder” is a new focus method designed to help you enter deep focus quickly. More than 400 people worldwide use it every second. With this method, you can stay focused for up to 90 minutes, improve your attention and memory, and enter a flow state more easily. == A New Focus Method == - Set a sound to play at random intervals (e.g., every 3–5 minutes). - Each time you hear the reminder sound, immediately close your eyes and rest for 10 seconds. - Then return to your work or study and continue focusing. Repeat this process until the 90-minute session ends. - After 90 minutes, take a 20-minute break. == Based on Four Core Principles == ■ Neural Replay During micro-breaks, your brain "replays" recently learned information at high speeds, improving memory retention and learning performance. ■ Variable Ratio Reinforcement Randomized feedback keeps the brain’s dopamine system engaged. Not knowing exactly when the next sound will occur maintains a healthy level of alertness and motivation. ■ Zeigarnik Effect Briefly interrupting a task creates a psychological "open loop." This makes your brain more eager to complete the task, helping you dive back in more effectively. ■ Ultradian Rhythms (90/20 Rule) The human brain naturally operates in 90-minute high-frequency cycles. Following this rhythm prevents burnout and maximizes mental endurance. ====== Personal growth website: https://zeenzeen.com Creator: 择恩 ====== “Random Reminder” can be downloaded and used for free.

DoMore is your own private AI assistant - one assistant, serving one person. - Just say it Tell it what's on your mind. It keeps track, asks the follow-up questions, reminds you when it's time, and can lay out your day for you. - Everything in one place Health, cards and documents, orders, schedule and travel, people, pets - filed under categories you can query in one sentence. - To-dos and reminders "Remind me to pay the rent next Wednesday" - it comes back to you on time; say the word and it's done. - Connect the agents on your computer (optional) Link a pi session running on your own machine and put it to work from your phone. You can connect several; one being offline doesn't block the others. The app walks you through three steps. - Privacy To answer, it shares only the snippets that request needs with a third-party large-model service - never your account details or the whole archive, and never for training. We tell you this plainly the first time you use the assistant, and you can withdraw any time.
