The biggest issues for me which I'm sure will hopefully be correct with firmware or app updates.
BIG NEGATIVES
1. I also noticed that S Health is not updated to work 100% with the Gear Fit. It attempts to have you download the Gear manager and not the Gear Fit manager to sync the pedometer.
2. I don't run and I seldom go for walks or hikes so my go to Exercise reason for buying the Gear Fit was the Cycling component. Big time bust as of day 3. I commute by bike and I have attempted to use the exercise function on the gear fit 7 times as of this morning. It has failed to record all 7 of the rides accurately. It generally will shut off and quit recording data 5 to 10 minutes into each ride. Once I restarted it 3 times in a 7 mile 28 min ride giving me 3 sets of partial data with missing time from when I didn't notice it had shut off. This makes it useless for cycling. It pops up a message about inactivity or something and trust me I am moving on down the road when it happens.
3. Pedometer on Gear Fit and S Health are off by a good bit at the end of each date. 11000 vs 15000 steps as an example. I haven't had a chance to go on a long measured distance walk with a hand clicker to see which is more accurate.
4. Heart Rate data seems to be accurate when resting but is not the very accurate while actually exercising.
5. The stopwatch needs tweaked. When using this at a track meet it doesn't report the final lap time. This needs explained. The gun goes off for the mile (4 laps) and the race starts as you hit the start on the stopwatch. As the first, second, and third laps finish you hit the lap button. As they approach the finish you hit the stop button as they finish. Results on the watch show your final time but when you hit the lap results it only shows you laps 1, 2 and 3. You have to take the final time and subtract the total of the 3 laps to get the 4th lap. Seconds plus hundreths times 3 laps subtracted by total time in your head is not a lot of fun. Hitting the lap button a 4th time allows the clock to continue so you get all 4 laps but you then have to total the 4 laps in your head to get a total time. Solution - Firmware the 4th lap into the results when you hit stop button after using the lap button during the timing.
POSITIVES I DIDN'T EXPECT
1. I wasn't even interested in the notification function when I ordered it and it is my favorite thing so far. (Partially because the cycling component is a bust right now.)
2. The sleep function is interesting.
3. Looks and Feel - Love the feel and it looks impressive.
I'm confident it will get corrected as more and more people purchase them and they work out the bugs.
