Blue Signum 'Lime AI' Breaks into Global App Market's Top Tier

BlueSignum, a global mental wellness startup, announced a flying start for its ambitious AI-based stress management solution, ‘LimeAI’, which received keen attention from the global market right from its debut at MWC 2025 last March. Immediately after its launch, LimeAI achieved the remarkable feat of ranking No. 1 in the new health app category on the Google Play Store in the UK and Canada, and No. 2 in the US. It also garnered positive reactions in major European countries including Spain, France, and Ireland, laying the groundwork for a successful global expansion. This success was largely due to the official announcement and promotion at MWC 2025 in Barcelona, Spain. As a personalized stress management solution, it attracted the attention of the AI and healthcare industries, demonstrating its power by surpassing 10,000 users within a month of its service launch. Yoon Jung-hyun, CEO of BlueSignum, stated, "While the initial response, hotter than expected, is encouraging, we still have a long way to go to achieve the true impact we aim for." He further expressed his ambition, "Through continuous quality improvement and research and development, we will deliver practical and meaningful experiences to users." The core of LimeAI is its cognitive empathy-based AI counseling function, which delicately analyzes users' emotions and stress factors and guides them through conversations. The 'Stress Report', provided based on inputted information, diagnoses internal and external factors and suggests 32 customized management strategies. Recently, a 'Trend' feature has been added, allowing users to see stress change trends at a glance based on counseling data, further enhancing its completeness. Based on LimeAI's excellent technology and user experience, BlueSignum is accelerating its penetration into the US market, focusing on professions vulnerable to stress. It also has future B2B market expansion in mind. Lee Sang-ah, Vice President, stated, "We have confirmed high demand for LimeAI in global markets, including the US." She emphasized, "We will successfully establish ourselves in the US market through multifaceted strategies and evolve into an AI solution that substantially alleviates users' psychological burdens."
