Hi,
Not sure if the Connect IQ API would actually permits to do this, but it would be great to have an app to log your daily body weight and synch it with GC.
Thanks for your consideration,
Cheers,
Ben
Unfortunately, there is a $2000 license fee that a developer must pay to get access to the Garmin Connect web service. Without access to the service a developer cannot legally do what you are asking for. It might be free to do through other services though.

PS: i track my weight on myfitnesspal every morning with my iPad, syncing with garmin works great.
But I do not use mfp for calorie counting
