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.
