## What is Random Reminder?

“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.

### 4/5 — Mac 版本没有了

*2026-07-12*

软件是个好软件，新增的 V2 算法看起来也不错，就是更新后 Mac 版本没有了，这对电脑学习的影响非常大！

**Developer response:** Mac版的存在只有负面影响，没有正面收益，所以取消了。

没有人因为有Mac版而给出好评。也似乎没人，是因为有Mac版而变成付费用户。

相反，一旦Mac版出现了问题（例如兼容性问题，或者bug），反而会收到一些拉低评分的评论。

为了解决Mac相关的问题，需要付出不少时间和精力，最后还得不到正向反馈……

所以后面干脆把Mac取消了，既节约时间精力，好评率反而上升。

（现在才知道：怪不得很多APP就是不做Mac版本，自己体验过就懂了）

### 3/5 — IDK

*2025-12-01*

I don’t understand why this app has purchase, I’d rather implement one by myself … It’s super easy

**Developer response:** Thank you for your feedback.

The core features of the app are completely free, and the paid part only helps support ongoing development and maintenance.

Publishing and updating an app also requires certain costs, so I set the price as low as possible to keep the project sustainable.

If you believe this tool should be fully free for more people, I truly appreciate that idea as well.

You’re welcome to contact me via email to sponsor the project, and once there is enough support, I will open free downloads to benefit more users.

Thank you for your interest in the project!
