A recent lifestyle app has experienced explosive growth in the market. The core logic of this product is surprisingly simple: users check in daily and set emergency contacts, and the system automatically notifies emergency contacts if the user fails to check in on time. This seemingly basic feature design has sparked widespread user resonance in a short period.

The app is priced at 8 yuan in the Apple App Store but achieved a daily growth rate of 500 to 800 times based on its initial user base. Such performance is rare in the app industry. As the user base expanded, the product also underwent a brand upgrade, with a new name that is more internationalized. Currently, the app has expanded into the US market and has become its most important overseas market, laying a foundation for further global growth.

From a commercial value perspective, the valuation of this app has already approached 100 million yuan. From a minimal viable product (MVP) to market recognition and then to a breakthrough in valuation, this case fully demonstrates how a simple product can achieve exponential growth by addressing genuine user needs.
