Question: Do you need to hit a ball for the analyzer to work? Or can you just swing, ie inside your living room, and and it works?
Document: The Swingbyte 2 is well worth the $149 even through only the old features work on my android devices. I do not get video on my android Samsung S3.My IPad does have synced video. The recent version includesthe target alignment line.Line drawing for analysis of the video (this is awesome)Sharing of your swing diagram and data (only need a good couch to suggest changes. )To get a good video, one must have their IPad on a tripod. Only the camera on the back works.
When this thing works, it IS really helpful, there's no denying that! If you hit the dirt (or sweep the mat) pretty much at all before you strike the ball, which I have a real problem with, the swing will not register about 4 times out of 5 which is frustrating, not that you'd want to see the analysis of those swings anyway...but you get the pointAlso, the battery holds more than enough charge for a few range sessions which is nice.
The Swingbyte 2 gives excellent data for everything you're interested in. It is really tough to get this thing aligned for swing path just right though. It's guess at ball flight is totally off. It was worth a try though. Definitely good to help ensure a good angle of attack and inside path to the ball. Won't replace the feedback of ball flight though
Works perfectly, Swinbyte makes backyard practice  meaningful, even the ball does not fly more than 4 meters  you will get all the essentials from your swing.
2:  The software rarely if ever catalogues a swing. There device claimed it was connected but would not  recognize my swing. I swang clubs in the house hitting Nerf balls, at the range hitting real ball and on the course, and of the hundreds of swings I took it logged only four. 3:  The Bluetooth doesn't work. It just doesn't.
The use of this device is allowing me to adjust my take-away, and down-swing to hit the ball more consistently.I have a 5 month window during winter here in Maine where I will not play much if any golf. Practicing indoors WITH A PURPOSE is a must to be ready for golf this next spring.
I swing my driver 105mph on average (if I keep it in play I'll hit between 230 and 300 yard drives) according to the swingbyte device and swing my irons between 70 and 80mph. When I hit the ball off the hossle or skull it, the device usually rattles loose and it slides down the shaft.
It really doesn't matter how good the Bluetooth connection worked, how good the software is if the device won't secure itself to the shaft without twisting and throwing off the measurements. After less than 5 swings even on solid contact, not jarring the club from a mishit, the device moves. I have a high dollar real feel golf mat that you can actually swing through the ball without hitting the pad but it doesn't seem to matter, the method Swingbyte uses to attach the device to the club doesn't work.
Good product, although the strap tore up after the first use, and Swingbyte replaced it within a week. You have to realign the device almost everytime you hit the ball as it moves more and more the longer the club. The top speed measurement in the swing view sometimes doesnt match with the swing data. About a third of the time it doesnt recognize youve made a swing and nothing gets recorded unless you reset it.
So excited to receive my swingbyte 2 but couldn't try it out immediately due to travel. Tried it in the living room to no avail...didn't record anything. So took it to the range today. Here is my review:1)  Looks cool, but have to adjust the thing after EVERY SINGLE SWING!
Answer: yes
