All it takes is the app on our coaches phones, and the sensor and we can accurately track any 10yrd dash, 40yrd dash, or any sprint/agility drill. Our old laser gates took so long to set up and were a hassle. JAWKU solved that problem. We recently just got JAWKU Jump and now we can test our athletes vertical jump heights from any where with only the phone and sensor. Highly recommend. Also, their support team is very helpful. We reached out wi the some questions and they explained to us that it is fine when the sensor disconnects at longer ranges as it will reconnect and transfer the data once back in range of the phone during the test. ### 2/5 — Great concept but unreliable *2025-04-13, version 2.5.12* Almost really cool! Maybe it’s my phone… but it’s hard for this to work if I’m testing anything over 40yd. I’ve tried so many different ways and still nada ### 5/5 — Combine Testing *2025-02-25, version 2.5.12* Amazing timing and jump tech we use for our combines ### 2/5 — One Major Problem *2025-02-13, version 2.5.12* Don’t get me wrong, I think the concept behind this Jawku speed system is very smart. I find the product very easy to set up and pretty fundamental as far as understanding the app. But the one major problem I have with this system is the fact that… well… it hardly ever picks up on the times I run. I literally just finished doing two 30 meter time trials and it literally did not record either of them, pretty much messing up my ability to be able to track my improvement from the last time I did the same trial. It genuinely drives me crazy that everything can be so good about the app and the system itself, except for the most important aspect of the system. I would be perfectly fine if the reaction timing, data records system, complexity of setting up etc were somewhat messed up if it meant I would at least be able to ensure that my times would be recorded. I honestly don’t know what else to say other than the fact they may have wasted a lot of potential with this system by simply not homing in on making sure the primary focus of the system actually worked. ### 1/5 — Don’t waste your money. *2025-02-06, version 2.5.12* Chinese garbage that doesn’t work out of the box. ### 5/5 — Nick Williams-Powerlifitng/Strongman *2024-12-05, version 2.5.12* So I typically don’t test my vertical or speed training ever, I do Strongman and powerlifting. This time around was a little bit different though. I met the Jawku team at a show and wanted to try the vertical training out to see what kind of force I was putting off the ground and how fast I was accelerating when doing short sprints. I was surprised at how accurate the measurements were and I was surprised at how fun it was to see my vertical jump go up every single time that I did it! It was even cool to see how they incorporated fun sounds and get my competitive drive going like when we were kids with their products to make the experience more enjoyable. I will give this product an easy 10 out of 10 and would encourage athletes to use it as well so that they can track their metrics on the fly versus having to pay thousands of dollars to get it done . This IS a complete game changer for anyone that wants to take their training and athletic abilities to the next level. Check out Jawku speed today and bring out your inner athlete! ### 5/5 — Perfect for Acceleration Drills *2024-08-13, version 2.5.12* As a former pro athlete and basketball coach Jawku Speed helps me to make my players faster and more agile. I love when it displays NEW RECORD alert ❤️highly recommended. ### 5/5 — Amazing for self timing! *2024-08-13, version 2.5.12* The Jawku is great for timing yourself accurately and easily. Only takes a few seconds to set up and I can track any of my agility drills including a 5-10-5. Also use to track my 10yrd and 40yrd sprints. The sports performance center I train at showed me Jawku, they use them to run through tons of athletes during our sessions quickly. ### 1/5 — Setup *2024-08-11, version 2.5.12* Setup is very frustrating and not intuitive. Had to do research on my own why mine wouldn’t connect. There aren’t even I stractions on how to charge it. Very underwhelmed and I haven’t even made it to the track yet. ### 5/5 — Great Product! *2024-07-25, version 2.5.12* First of all I want to say this is one of the best ways to time yourself if you are serious about improving your speed. For a way cheaper price you get a product that has the premium qualities of the most popular timing devices. Also it’s insanly easy to use, time efficient and they have great customer service if you need help. ## Frequently asked questions about JAWKU ### What does the JAWKU Speed app do?
