## What is TechDisc?

TechDisc for iOS makes it simple to connect to your TechDisc and begin measuring Spin, Speed, Nose angle, Hyzer angle, Launch angle and Wobble at home in your net or at the practice field.

TechDisc is an innovative new tool to Know Your Throw, with hardware and software designed by disc golfers to accelerate every athlete's progression in the sport. 

A suite of sensors permanently attached to the center of a golf disc measures the forces and angles put on a disc. The data is transmitted to the app and uploaded to the cloud to crunch the data and determine throw type (Backhand, Forehand, Thumber, etc.) and angle (Flat, Hyzer, Anhyzer) to easily sort and filter your throws. 

Measure your drive, upshots, standstills, hyzers, rollers and anything else you want to improve. Find average spin for your forehand shots and backhand shots with a tap. Know if that 70 MPH throw was a fluke or if you can count on it consistently.

### 5/5 — Vast improvement

*2026-07-22*

I’ve had a destroyer tech disc for a little over a month. I’ve been watching videos and working hard on trying to improve my game with minimal results for the past 4 months. Since I’ve had my tech disc my nose angle went from +10 to -2.5 average and have added 50 + ft to my drives. I would consider this one of the best tools to improve your game. If you don’t have one find someone who does just to get a baseline for your mechanics

### 4/5 — Advance ratio needs to be in app

*2026-05-28*

The advance ratio needs to be in the app. I’d like to see this metric alongside the other six metrics to tell at a glance, if I’m putting good spin on the disc in relation to my speed.

### 5/5 — Instant Feedback

*2026-05-03*

I finally bought a TechDisc. Should have done this a year ago. I’m 65 and didn’t start playing until I was 60. I’ve increased my arm speed by 10 MPH in less than a week. I’m up over 55 MPH now and still climbing. I’m throwing 350+ and beat my friends that are 10 years younger than me. Can’t wait to break 400 feet! Thank you TechDisc!

### 5/5 — Great Tech - great company

*2026-05-02*

The TechDiscs are outstanding products  for improving your game.  I threw mine 7000+ times in 2025 - every shot in my game has improved.  The app is equally excellent - the telemetry alone is invaluable.  The video feature, with auto slow-mo in the power pocket, is incredibly useful for debugging your form.  Company continues to innovate their software and provides great support when things go wrong.

### 3/5 — Connect button

*2026-04-07*

The connect button needs more padding from the bottom. It is consistently difficult to select throws because of the placement of the connect button and the iOS action bar at the bottom.

### 5/5 — Best tool

*2026-03-23*

The tech disc is fun and a great learning tool. Wish there was a free trial with disc purchase for simulated courses to see if it’s worth $99 bucks or if it’s busted simulator. I may find out this winter.

### 1/5 — Broken

*2026-02-15, version 0.3.25*

Too many connection issues.  Linking to game impossible even with subscription.

### 4/5 — Depressing

*2025-12-05, version 0.3.21*

The TechDisc works great.  But it’s hard facing the truth that my throws are consistently bad.  I’m trying different things to get my nose angle to a respectable level but no luck yet.  Also my speed, wobble, launch angle and RPM’s suck!  I’m sure once I figure out what I’m doing wrong I’ll feel much better here and on the course.

### 4/5 — Great, if you know what everything means.

*2025-10-17, version 0.3.21*

This is a great tool to use to figure out exactly how you are interacting with a disc. However, the TechDisc tagline is very appropriate there: "Know Your Throw,": The app as it is currently (10/2025) is just an interface for players to get data and that is it. It's set up and geared towards players who are already intimately familiar with all of the metrics this measures, what good versus bad metrics are, and how to adjust them for an ideal throw in a given situation. They "Know Their Throw," or at least understand it.
The TechDisc website does offer an explanation for the metrics, but you have to navigate to Support, then Before You Buy to find the Tech Disc Metrics page where the explanation is. While training in the off season, or throwing in a field (where cell service might not be great), that kind of navigation can be a bit cumbersome and time-consuming, especially if you're in a groove in a training session.
I understand that this tool can be considered something for experienced players that have developed bad habits, are looking to break through a plateau, or who are looking to improve in general, but it leaves us newbies out in the cold when we are trying to establish good habits and muscle memory from the start. It would be nice to see an in-app knowledge base that answers quick questions ("Okay, my launch angle is 12, is that good or bad?" and "Where does "Flat" stop and "Anhyzer" begin?") with the option for more information. We're already innundated with a ton of new terminology; having a quick answer in the moment would really be helpful. Partnering with any of the companies that provide the molds (and thus probably have sponsored players) to create short explanation videos you can access in the app would also be great.

### 5/5 — Best disc golf training tool. Period.

*2025-08-14*

60 year old trying to transition from recreational player to something more advanced. Bough the tech disc with reservations given the price tag. Turns out it was worth every penny. Am currently trying to throw nose down which is insanely hard to do. Seems that, using tech disc, I’ve kinda got it after three days or so (250 throws). I don’t believe I would have gotten the same results in 3+ weeks of field training. Money well spent.
