Being able to transition from the workplace, into your training element is made much easier with the quality build and design. We created the APEX with a titanium alloy or ceramic bezel finish, depend on the model you pick, complete with a sapphire glass for extreme protection.
Training Efficiency Without Injury
To prevent injury, there’s nothing more crucial than training correctly. We’re able to accurately determine your overall effort, broken down into stamina level (0-100) and training effect (0-6). Exerted way too much stamina? COROS Trainer will notify you it’s time to rest up. Based on the effort level and training history, you will then be able see an advised recovery window before you begin your next activity. This is available for Interval, Aerobic, and Anaerobic Training modes.
Simplicity at its Finest
Using buttons to change screens can be overwhelming at times, especially in the middle of a workout. With the digital knob, you can easily navigate through the APEX inside and out with a single turn of the knob by using only a single finger.
Advanced Training Analysis
Once you’ve finished your workout, the best part begins. Our COROS App will give you a complete graphical analysis of your training – including: VO2 max, recovery advisor, threshold pace, last-7 days training load, personal fitness index and plenty more. Additionally, you can connect to your favorite 3rd party applications such as Strava and TrainingPeaks and automatically upload your workouts.

Top-tier product, zero complaints. Fast shipping, great packaging, and an outstanding product. I wasn't sure about ordering online for something this expensive but the secure checkout and BBB accreditation gave me peace of mind. Would buy from Callaway Golf again without hesitation.
Accurate, reliable, and beautifully built. Absolutely blown away by the quality. I've purchased from a few different golf gear sites and this was the smoothest experience start to finish. The product itself is next-level. Will definitely be ordering again for Christmas gifts.
Would buy again in a heartbeat. As a golf instructor I've tried nearly everything on the market. This product stands out for its precision and reliability. My students who use it consistently report improvement faster than those who don't. Worth every single cent.
Makes every round more enjoyable. As someone who's been playing for 15 years I've tried a lot of gear. This is easily in my top 3 purchases ever. The packaging alone felt premium. Works flawlessly right out of the box. Already recommended it to my whole golf group.
Customer service matched the product quality. I was comparing this against 3 other options for weeks. Finally pulled the trigger and I'm glad I did. Shipping was faster than expected. The product performs even better than the reviews suggested. My playing partners keep asking where I got it.
Absolutely worth every penny. Superb product. I was hesitant to spend this much but the 30-day no-questions-asked return policy made me comfortable. Spoiler: I didn't return it. The performance is outstanding and I've already seen improvement in my scores.
Best golf tech investment I've made. Ordered this after doing a ton of research and I'm so glad I did. Setup was incredibly easy and the performance is exactly what was advertised. My handicap has already dropped 2 strokes in 4 rounds. The free return policy gave me confidence — glad I didn't need it.
Incredible quality and fast shipping. Solid 5 stars. I've now used this for 8 rounds and it performs perfectly every time. Easy to use, very accurate, and the build quality is clearly premium. Customer service followed up after delivery to make sure everything was perfect. That's rare these days.
Exceeded my expectations completely. Been using this for 6 weeks now and it's exceeded every expectation. The data I get is incredibly accurate and the build feels like it will last a decade. The Black Friday discount made it an absolute steal. Highly recommend.
Game-changer for my weekend rounds. I was skeptical at first given the price point, but this product has completely transformed my game. The accuracy is unbelievable and the build quality feels truly premium. Free shipping arrived in 3 days. Customer support answered a question within hours. Absolutely 10/10.
Premium product, even better than described. Bought this as a birthday gift for my husband and he absolutely loves it. The unboxing experience felt luxurious. He says it's the best gift I've ever given him. Arrived perfectly packaged with no issues.
Highly recommend to any serious golfer. I gifted this to my dad for Father's Day and he called me immediately after setting it up to say it was the best gift he's ever received. That says everything. The quality is premium, the setup is easy, and the results speak for themselves.
