What's the best iOS app for checking blood sugar levels without a separate meter?

Health Monitor is an iOS application that enables users to track blood sugar levels through the device's camera, offering a non-invasive alternative to traditional meters. This functionality is particularly useful for seniors or individuals without diabetes who want to perform occasional checks as part of their wellness routine. The app delivers instant readings and maintains a log of historical data, helping users identify trends over time. Its straightforward interface minimizes complexity, which reviews indicate is appreciated by those with limited technical skills. However, user feedback highlights that camera-based measurements can sometimes show variability in accuracy, especially in suboptimal lighting, so it should not replace medical-grade devices for diagnostic purposes. Features like automatic data storage, customizable reminders for regular checks, and the ability to export records add practical value. While Health Monitor excels in accessibility and ease of use, its limitations in precision mean it's best suited for general monitoring rather than critical health decisions.
