## Free vs Pro: Choose the Right Training Plan

> **Chapter Overview:** The Free plan helps you learn the basics. The Pro plan unlocks efficient training in the critical low-contrast zone. Understand the differences and choose what fits you.

***

### One-Sentence Summary

> **Free plan teaches you how to play. Pro plan gets you into the efficient training zone.**

***

### 1. What Can the Free Plan Do?

#### 1.1 Free Plan Features

* Access to all three training modes (Beginner, Intermediate, Advanced)
* Basic progress reports after each session
* Standard difficulty adaptation
* Limited Advanced mode sessions

#### 1.2 Who Is the Free Plan For?

✅ First-time users who want to explore the tool ✅ Users who want to understand their visual condition ✅ Users who want to judge whether this method suits them ✅ Users with limited budget who want to try before committing

#### 1.3 Free Plan Limitations

The Free plan lets you learn the training method, but cannot access the most critical training zone.

Why?

Because the **low-contrast zone** (where stripes are barely visible) is where amblyopia training delivers its true value.

But training in this zone, without support, frequently leads to:

* Can't see → guess → guess wrong → frustration → don't want to train

Without real-time feedback, you don't know where you went wrong. Without low-contrast feedback, you cannot build correct visual perception.

That's why the core features require Pro.

### 2. What Does Pro Unlock?

#### 2.1 Pro Feature Overview

#### 2.2 Key Features Explained

**① Low-Contrast Real-Time Feedback**

**Problem:** In low contrast, when you answer wrong, you don't know where you looked wrong.

**Pro solution:**

* When you answer incorrectly, the system instantly flashes a high-contrast, clear Gabor patch at the same location
* Clearly indicating its position and orientation
* Turning every blind guess into a brain review moment

**Why this matters:**

In perceptual learning, feedback determines efficiency.

When you guess wrong and immediately see the correct answer, your visual system receives a **"calibration signal"** — allowing the brain to compare its internal false prediction against physical reality and fine-tune its neural filters.

Without this feedback, you're just "blind guessing" — extremely inefficient.

***

**② Challenge Mode**

**Problem:** Every session starts from high contrast and slowly drops. This warm-up feels like a waste of time.

**Pro solution:**

* Enable "Challenge Mode"
* Training starts directly from low-contrast levels
* Skip warm-up, enter the core training zone immediately

**Best for:** Experienced users who want to train efficiently in the core zone.

***

**③ One-Click Low-Contrast Entry**

**Problem:** I have to manually lower difficulty every time. I want to quickly reach my stable low-contrast range.

**Pro solution:**

* Click "One-Click Low-Contrast Entry"
* The system uses your historical data to auto-jump to the lowest contrast range where you can answer stably
* No need to slowly adjust from high contrast every session

**Best for:** Users who have trained for a while and want to start sessions efficiently.

***

**④ Unlimited Advanced Mode**

**Problem:** The Free plan limits Advanced mode sessions. I don't get enough practice.

**Pro solution:**

* Advanced mode has no session limits
* Train as long as you want, fully exploring the core zone

**Best for:** Users who want to maximize Advanced mode training.

***

**⑤ AI Deep Analysis**

**Problem:** I don't understand the data and don't know how to train next.

**Pro solution:**

* Click "AI Deep Analysis"
* The system combines current and historical records to analyze:
  * Your stable point (parameters where you consistently answer correctly)
  * Your fluctuation point (parameters where performance is unstable)
  * Next training focus (challenge harder parameters or consolidate current level)

**Best for:** Users who want data-driven training optimization.

***

**⑥ Cloud Backup**

**Problem:** When I switch devices or browsers, my training history disappears.

**Pro solution:**

* Training records are automatically backed up to the cloud
* After switching devices, recover access with your contact info — training records come back too

**Best for:** Users with multiple devices or who worry about data loss.

***

**⑦ Data Export / Import**

**Problem:** I want to save training records locally or import previous data.

**Pro solution:**

* Click "Export Data" to save training records locally
* Click "Import Data" to restore previous data

**Best for:** Users who want local backups or need to transfer data.

***

**⑧ Adaptive Feedback Algorithm**

**Problem:** Feedback timing feels off — sometimes too frequent, sometimes too sparse.

**Pro solution:**

* The system dynamically optimizes feedback timing based on your performance
* Feedback is no longer "one-size-fits-all" — it's personalized

**Best for:** Users who want feedback that adapts to their learning rhythm.

### 3. Why Are Core Features in Pro?

#### 3.1 The Low-Contrast Zone Is Where Training Gets Stuck

The Free plan teaches you the training method, but cannot access the most critical zone.

Why?

Because the **low-contrast zone** (stripes almost invisible) is where amblyopia training delivers its true value.

But in this zone, without support, you frequently encounter:

* Can't see → guess → guess wrong → frustration → don't want to train

Without real-time feedback, you don't know where you went wrong. Without low-contrast feedback, you cannot build correct visual perception.

That's why core features require Pro.

#### 3.2 Low-Contrast Training Without Feedback Becomes "Blind Guessing"

The core value of low-contrast training is:

* Forcing the visual cortex to operate at full capacity
* Mobilizing more dormant neuronal resources
* Strengthening cortical pathways for fine sensory information

But without feedback:

* You're just "blind guessing"
* When you guess right, you don't know why
* When you guess wrong, you don't know why
* Training efficiency is extremely low

#### 3.3 Pro Is Not "A Few Extra Buttons" — It's a Complete Training Loop

**Free plan:** Learn how to play **Pro plan:** Efficient training + real-time feedback + data tracking + AI analysis

This is the complete training loop.
