My family and I really enjoy mountain climbing. Every trip always provides new experiences, from soothing natural scenery and fresh air at high altitudes to unforgettable moments of togetherness. However, lately there have been many concerns as we increasingly hear news about popular mountains experiencing sudden eruptions. There have also been numerous cases of hikers getting lost or missing during their climbs, whether due to bad weather, unclear trails, or a lack of information and preparation. Seeing this situation, I thought of creating an app that could help hikers stay safe and informed.The main purpose of this app is to help beginners climb mountains safely, comfortably, and enjoyably. Many people want to try climbing for the first time, but often feel hesitant due to lack of experience, limited knowledge about mountain conditions, or fear of encountering unexpected situations. With this app, I want to ensure that anyone—including new climbers—can enjoy a pleasant climbing experience without constantly worrying about potential risks.
