Lark is a text-based health coach that helps you reach goals such as weight loss, diabetes prevention and management, blood pressure control, stress reduction, increased activity, and improved nutrition. Available 24/7 on smartphones and tablets, Lark delivers personalized guidance, habit-based lessons, and tracking tools through short conversational interactions so users can build routines at their own pace. Many people access the app at no cost through participating health plans, and it can pair with compatible tracking devices to monitor progress without appointments or scheduled sessions.

Key Features

24/7 conversational coaching adapts to user responses and daily schedules, providing short habit-focused lessons and reminders. Lark's CDC-approved Diabetes Prevention Program (DPP) is delivered through personalized lessons, goal setting, and progress tracking. The app supports food and activity tracking and can connect to smart scales and other compatible devices. Programs cover weight loss, diabetes care, hypertension, sleep, stress and nutrition, and are available on both phones and tablets for flexible access.

Advantages

Eligible members often receive access at no cost through participating health plans or employers, making clinically recognized programs more accessible. The platform offers condition-specific coaching for diabetes and hypertension and continuous, text-based support that lets users work at their own pace without scheduled appointments. Lark integrates tracking tools and optional device support, and some plans may include community or group coaching elements.

Disadvantages

Free access typically depends on participation by your health plan or employer, so eligibility may vary. Entirely text-based coaching may not suit users who prefer face-to-face or video sessions. The app requires a smartphone or tablet and provides the fullest tracking features when used with connected devices.
