The Stack System Review: I Gained 4 MPH. Worth $299?
I covered Rypstick. I covered SuperSpeed. Both are $199. Both work. Both have thousands of happy users on Reddit posting speed gains that make the rest of us jealous.
The Stack System costs $299. That is $100 more than either competitor. For that extra hundred bucks, you get one club instead of three, a set of interchangeable weights, and an app that is genuinely smarter than anything else in the speed training space.
Is the premium worth it? I spent six weeks with The Stack to find out.
What You Get
The box contains a 41.5-inch training club, five milled Stack weights, and a dual-purpose weight case that doubles as a phone stand. No radar. That is separate.
The five weights give you 30 combinations from 0g to 300g. You are not locked into three fixed sticks like SuperSpeed. You are not sliding a single weight up and down like Rypstick. You pick specific weights for specific drills based on what the app tells you. It sounds fussy. In practice, it takes about 15 seconds to swap weights between sets.
The club itself is 41.5 inches. That is roughly the length of a 7-iron. This is the single biggest complaint The Stack gets from reviewers and users. The goal is driver distance. Why train with a 7-iron-length club? I will get to that.
There is also a Junior version at 38.5 inches. SuperSpeed does not have a junior-specific model.
The App Is the Product
If The Stack were just a club with weights, it would be a worse deal than Rypstick. The app is what makes it different. It is not an add-on. It is the product.
The Stack app was created by Dr. Sasho MacKenzie, a biomechanics researcher who has spent years studying how golfers generate speed. This is not a generic workout timer with a leaderboard bolted on. The app runs you through a baseline assessment called Load Velocity Profiling. It has you swing your driver plus several Stack weights and maps your speed curve across different loads. Then it picks the training program that fits your specific profile.
Some golfers are βvelocity dominant.β They swing fast with light weights but struggle under heavy load. Others are βforce dominant.β They crush heavy loads but cannot max out on lighter sticks. The app diagnoses which one you are and customizes the protocol. SuperSpeed gives everyone the same three-stick sequence. The Stack adapts to your data.
Once you start training, the app adjusts session by session. It looks at your speeds from the previous workout, compares them to your history at each weight, and tweaks the next sessionβs weights and rep count. The more you use it, the smarter itgets.
There is also a Grit score. It tracks how consistently you train. Miss a session? Your Grit drops. Hit every workout? The number climbs. It sounds like a video game mechanic. It works. Seeing a number that says β90% complianceβ is more motivating than you would think.
Platform Availability (This Changed Recently)
For years, The Stack was iOS only. That was a dealbreaker for Android users, and we called it out every time it came up.
As of mid-2026, The Stack is now available on Android (Beta) and Chrome Web (Beta) in addition to iOS. The Android and web versions support the core speed training programs and the Learning Library. The Stack Putting and Stack Wedging apps are still iOS-only for now. If you are on Android, you can do the main speed training protocol. The putting and wedge features will come later.
This is a meaningful update. Android users no longer have to buy a used iPhone just to train. The web version means you can even use a laptop if your phone is old.
What Training Actually Feels Like
My first session was humbling. The baseline test had me swing my driver eight times. Average: 96 mph. Then the app had me swing the Stack at 280g, 195g, 145g, and 95g. Then trail arm only at 0g. Then lead arm only at 0g. By the end I was sweating and my max Stack speed was already higher than my driver speed. That neurological effect kicked in within 20 minutes.
A typical session takes 15 to 25 minutes. You get 90 seconds to two minutes of rest between sets, and 10 seconds between individual swings. The app calls out every weight change, every rep count, and every rest interval. You never have to think. You just swing.
The three swing types are:
- Full Swing: your max controlled swing, the one you would use on a par 5
- Max Effort: swing out of your shoes, balance be damned. This is about finding a new ceiling.
- Step Swing: start with feet together, step forward into your downswing. This trains sequencing and weight shift.
A program is typically 18 to 24 sessions, done two to three times per week. That is six to ten weeks per program. The app includes multiple program types: Foundation for beginners, Full Speed Spectrum for experienced users, Neural Drive for advanced training, and maintenance programs for keeping gains in-season.
Real Results
This is where The Stack earns its price tag.
I gained 4 mph of driver swing speed in six weeks. Baseline was 96 mph. My final progress check registered 100 mph. That is about 8 to 12 yards of carry distance. Not life-changing. But real.
A 56-year-old golfer documented his results on MyGolfSwing.net: he went from 89 mph to 106 mph across six programs over 15 months. After adding strength training alongside The Stack, he pushed to 111 mph. That is 22 mph gained at age 56. His handicap dropped from 7 to 3 over the same period.
A Fit For Golf user posted gaining 9 mph and dropping from a 10 handicap to a 6.4. Another user at 54 years old gained 8 mph. Multiple Reddit threads show users gaining 5 to 10 mph after one or two programs.
The common thread is consistency. The Grit score keeps you honest, and the data visualization keeps you motivated. I found myself wanting to see the line go up. I trained more because the app made it satisfying.
What I Did Not Love
The 41.5-inch length annoyed me for the first two weeks. When you train with a 7-iron-length club and then pick up your driver, the driver feels long and awkward. The transition is not seamless. Rypstick at 45 inches mirrors a driver length and makes the handoff feel more natural. I understand The Stackβs reasoning. A shorter club is easier to swing fast with one arm for the trail-arm and lead-arm drills. But it is a tradeoff, and I noticed it.
The data heaviness can be overwhelming. Every session generates charts, trendlines, and comparison tables. If you are a 20 handicap who just wants to swing faster, this will feel like homework. SuperSpeed is simpler. You pick up a stick, you swing it, you move on. The Stack demands more engagement. For the right golfer, that is a feature. For the wrong one, it is friction that leads to quitting.
The price includes one year of app access. After that, the app requires a paid membership to continue. The Stack does not publish the renewal price prominently on the product page. When I dug into the help center, the ongoing subscription was not clearly stated. That lack of transparency bothers me. If you are selling a $299 product with an app lock-in, tell me what it costs after year one.
The Stack Radar is not included. You need a compatible speed-measuring device. The official Stack Radar costs $289 separately, or you can buy the bundle for $499. A PRGR launch monitor works too and costs about $200. Either way, factor another $200 to $300 on top of the $299 club.Real total cost: $500 to $600 to get started properly.

The Verdict
Buy The Stack if you are a data-driven golfer who will actually train. You want the best app, the most personalized protocol, and you are willing to pay $100 more upfront plus a future subscription for it.Your handicap is probably single-digit or close to it. You own a launch monitor or are ready to buy one.
Buy Rypstick if you want the driver-length training club, the simpler experience, and the one-time $199 price with no subscription. You will get similar speed gains with less data overhead.
Buy SuperSpeed if you want proven results at the lowest price and you do not mind storing three sticks. The protocol works. The app is basic but functional. The track record since 2014 means something.
Skip speed training entirely if you know you will quit after three sessions. The equipment does not matter. Your consistency does. If you are not going to train twice a week for at least six weeks, save your $299. Buy a dozen Pro V1s and a lesson instead. You will get more value.
I kept The Stack. The app is that good. Every time I open it and see my Grit score and my speed trend, I want to train. For me, the extra $100 bought accountability that actually worked.
