If you are a golfer, you need this equipment and app!

I’ve gained 13 mph, and 36 yards of distance. It really helps with my flexibility, so do the warmup every time you Stack, or golf.

Love the app / Classy operation

Been enjoying the limited time I had with Stack Wedges and was looking forward to utilizing the strokes gained features, however I suffered a torn Achilles outside of golf. I reached out about a possibility of a “hold” on my subscription and they immediately added an additional 6 months and wished me well on my recovery. So many other operations would just ignore me or say sorry can’t do anything about it but not TheStack. Thank you guys for the great app and being great humans.

Stack Stats

Do not select the free trial of stack stats yet. It’s currently bugged. It will charge you the full year if you have had a normal subscription in the past.

Needs instructions

I’m sure the app is great for increasing speed, etc. But the app itself needs more complete instructions or better layout . I’m a database developer, so I’m pretty app savvy, but this is hard to find your way around.
