App doesnt keep sync with time

When I first got my pebble steel in Dec 14 I really liked this apps ability to take activity data from the pebble and create a historical chart of data. As of late Ive found at times the apps synced data to be way off from what the pebble shows (like 2500 on watch to 200 on the app). Ive also been lazy about manually syncing every day and have found some days in history to be completely blank. This activity monitoring solution could be great, but needs some work before it can be depended upon.
