Lark is a great free app that makes use of Health app using the HealthKit API. Lark uses the lower power sensors in the iPhone 5s, iPhone 6, and iPhone 6 Plus to track your activity, eating and sleep data without draining your battery. No extra sensors are required, but it does require you to have your iPhone on you every time you move to collect data. Something that I am not too good at.
You can authorize Lark to share its data with Health app. This will allow you to use Health app’s simple and informative graphs and charts to analyze the health and fitness data gathered by Lark.
Simple and Easy to Read Charts
Lark’s simple and easy to read chart gives you an overview of your weekly activity and sleep data.
You can also see as detailed view of the data. The detailed view provides activity details, time span and duration.
Seamless Integration with Health App Using HealthKit API
Lark seamlessly integrates with Health app using the HealthKit API. Health app generates beautiful charts that contain an analysis of your activity including your activities and sleep history.
Light Banter Helps Keep You Motivated
Lark’s light conversation helps keep you motivated offering you charts comparing your activities of the current day to your averages (for weekdays and weekends).
Overall Lark is a fantastic app that allows you to easily track your health and fitness data and share it with Health app. You can’t beat the price (FREE) for a such useful app.
