Ive had this tracker for 24 hours and was very pleased with my purchase until I woke up this morning and had no trace of yesterdays tracked info?! The app has the charts option to view weekly and monthly stats on all the measured metrics and a personal best and daily average section, but apparently all of this is useless... Despite the ~3k steps I took yesterday (an estimate since the app has no trace of this info anymore), now, 8 hours later, my personal best stat is the 31 steps Ive taken this morning?!? How is this a fitness tracker if it does not actually let you track your fitness information?!?
