Hello! I'm looking to create a basic app to track how much water you've drank for the day (allowing you to specify how much water you just drank via a watch widget, and having that info get synced to my phone or as a data point). Is this possible with the current Connect IQ SDK? If not, can I make a feature request to have the API allow the tracking of custom data points (calories eaten, water drank, beer cans crushed against head, etc)?
You could use the FitContributor API to do this. It allows you to record custom data to a FIT file (which typically stores activity data, such as speed, heart rate, etc), so you could write an app that writes data with a button press or based on some other trigger to count items like you're wanting to do.
