Overview
- Users press a button to check in, and if they stay inactive for about 48 hours the app emails a preselected emergency contact.
- The app leads China’s paid App Store and has entered rankings in the United States, Singapore, Hong Kong, Spain, Australia and Germany, where it reached the top five paid utilities.
- Developers say they are weighing a new name and plan to add SMS or in-app messaging and improved accessibility; the iOS version currently relies on email alerts.
- Journalists and reviewers flag privacy and terms issues, including liability limits for data breaches and possible retention of some data after deletion.
- A small team of three young developers reportedly built the app for roughly 1,000 yuan and has discussed selling a 10% stake for about one million yuan.
