Full description

Challang is a simple, playful hydration tracker for the drinks you have throughout the day. Log water, coffee, tea, milk, and other drinks with their serving size. Challang applies a hydration credit for each drink and shows your progress toward today’s goal. As you log drinks, the water rises on the home screen so your progress feels visible. Key features • Quickly log drinks and serving sizes • Automatic hydration-credit calculation by drink type • Daily goal and progress tracking • Daily history and hydration-pattern insights • Personalized hydration goals • Optional reminders and supported health-app sync Challang is free to install. Free users can add up to 20 drink records per week. The monthly Challang Plus subscription removes the weekly record limit and adds cloud backup, Plus insight reports, and supported health-app sync. Health-app integration is optional. Challang does not provide medical advice, diagnosis, or treatment. Follow guidance from a qualified healthcare professional if you have a health condition or fluid restriction.
