## What is Hold+?

Hold+ is a training tool designed specifically for freedivers, breath-hold practitioners, and anyone looking to improve their lung capacity and concentration.

Whether you are a beginner in freediving, preparing for certification, or an advanced diver challenging the depths, Hold+ offers the most intuitive and distraction-free training experience. We've removed complicated settings and unnecessary social features so you can focus 100% on your breath and heartbeat.

【Key Features】
• Professional Apnea Training: Built-in standard CO2 and O2 training tables to help your body adapt to high carbon dioxide and low oxygen environments.
• Minimalist Interface: No redundant buttons or ads. Open the app and start training immediately.
• Completely Offline, No Login: Your training data is stored securely and entirely on your device. Train anytime, anywhere.
• Voice/Vibration Prompts: Clear guidance during training so you don't need to keep staring at the screen. Just close your eyes and feel your body.
• History Tracking: Log every training session and clearly track your progress.

Breathing is an instinct; holding your breath is a dialogue with yourself.
Download Hold+ now and discover your limitless potential underwater!

Disclaimer: This app is for daily training purposes only and is not a medical device. When performing breath-hold training, please ensure you are in a safe, dry environment (such as a bed or sofa). Never practice alone in the water without supervision.
