Please check your device's memory usage and internet connection. If the issue persists, contact support at support@lifesaversim.com. With your inquiry, please provide detailed information about your problem and device (brand, model, and operating system version).

The LifesaverSIM application will be beneficial to anyone regardless of their level of training. Everyone will be able to practice what they need in the simulator: some may be learning the basic steps of the MARCH algorithm, while others may be reinforcing and practicing previously acquired knowledge. Only regular training supports your knowledge at the appropriate level and develops automatic skills.

No application can replace working with a qualified instructor. The best approach would be to receive practical instruction or training from an expert to experience the manipulations firsthand. Then, one can practice the sequence of actions for providing assistance according to the MARCH protocol in a simulator, thereby developing cognitive skills.

LifesaverSIM has launched its first course TCCC ASM, designed for all service members. The course is created in collaboration with expert instructors and combat medics and is aligned with TCCC guidelines and STANAG NATO AMedP-8.15. It covers all key aspects of providing care on the battlefield.

Upon the first launch of the application, you will need to log in, thus requiring an internet connection. Furthermore, an internet connection is not required to use the application. You can use it in offline mode.

You can sync your progress across multiple devices using the same login account. Please note that a stable internet connection is required to save your training progress correctly.
