What It Is

Curis is a free web-based structured breathing exercise tool focused on modes such as Box Breathing, Triangle, Inverted Triangle, Simple, and Walking. The page highlights that these methods are used by Navy SEALs, athletes, and meditation practitioners for scenarios such as stress reduction, improved focus, and better sleep. Strictly speaking, it is not a typical AI application: the main content does not mention models, generative AI, intelligent recommendations, or automated personalized training capabilities.

Core Features

The tool offers a large number of breathing presets, such as Box Navy SEAL 4-4-4-4, Sleep Prep, Anxiety Ease, Morning Energy, and Focus Flow. It also allows users to customize the duration of inhaling, holding, exhaling, and resting. In terms of interaction, it includes a breathing circle animation, progress bar, phase prompts, text guidance, audio cues, mobile haptic feedback, full-screen mode, dark mode, and keyboard shortcuts. It also records total practice time and today’s session count, and supports setting a target number of minutes.

Pricing and Privacy

The main text clearly states Free, No accounts, no data collection, and no tracking, with no mention of subscriptions, paid versions, or trial limitations. In terms of privacy, the page says all data is stored only on the local device through browser localStorage and will not be collected, transmitted, or stored on external servers. The page also includes an advertising inquiry entry point, indicating that it may monetize through ad placements.

Pros and Cons

Its advantages are that it is easy to get started with, requires no registration, and offers a very rich set of presets, making it suitable for everyday stress relief and pre-sleep practice. Its privacy statement is also fairly user-friendly. The drawbacks are the lack of Chinese interface information, no API or integration capabilities, and no AI-powered personalized feedback. Although its health benefits are supported by references, the page also clearly states that it is for wellness purposes only and cannot replace professional medical advice.

Who It’s For and Access in China

Curis is suitable for individual users who want to quickly do breathing training, meditation support, anxiety relief, pre-sleep relaxation, or CPAP breathing practice. It is not suitable for users looking for an AI health coach, medical-grade monitoring, or enterprise integrations. The main text does not provide information on access from mainland China, so its availability is considered unknown.
