Sprint Stopper

Amazing. Could not find anything like this anywhere - only suggestions were £1000+ laser timing gates and systems which take up loads of room and setting up. This app is literally saving you thousands of pounds!! AND time deploying it! Little sketchy performance with me running music in the background too, but this is still early days for this app and a must have for sprint training. Awesome work!

Very good. Managed to get it to work. If all bugs were fixed then it would be awesome. Bugs: Disconnects bluetooth when app opened and turns it off. When connected it somtimes randomly disconnects. Please fix these. I managed to use the app and it's awesome. Very original.

Add a feature that can detect the distance between the phone and bluetooth speaker(feet/ meters) and this is 10,000% the best app of all time! Thank you so much. I go honestly didn't believed that this app was developed. You (guys) are the best!

This app does not work. I tried it on three different Android devices and used three different Bluetooth speakers. What exactly happens? After you select Deploy and answer the question regarding using Wireless speakers the app begins scanning. The app stays in SCANNING....but never connects to the Bluetooth. Even though it is making noises like it is connecting. It would have been nice if this had worked. However, there seems to be major bugs and it does not seem that the app was tested against more than one Use Case. After frustration I purchased a FreeLap timing system.

Hi Quincy, I am still faceing the screen off problem even when I done the update. Looking forward for the "sounds and pistol" Many thanks.

I love the app yet there hasn't been any updates for a long time I hope there will be one sometime soon for the gun shot noice and I hope you could add a feature for being able to change the 20 seconds before the get set... Thank you.

This app is still developing and Quincy has shown time and again that he listens to his customers and attempts to continually improve it based on feedback. Really looking forward to using this in training sessions throughout the summer at my athletic club.

Fantastic app for anyone wanting to train for track or any sport requiring acceleration. The repeat sounds stop after three rounds so just need to close and reopen the app. Sadly my bluetooth does not connect but I have a cheaper work around using my wife's baby monitor at either end. I also tried my son's handheld two way with the button depressed and that worked as well. I usually use the 10m to practice starts and sadly the correlation to 100m is fairly accurate so I need to work on my starts. You can download a separate reaction timer app (reflex or sprint start timer) and minus your reaction time to get a very close FAT 40 yard time (180ms to 330ms average reaction time depending on how old and sharp you are). If you use a connected speaker at the forty yard line don't forget to allow for the speed of sound approx 375 yards per second divided by 40 yards (minus 0.107 ms and approximate pre-measured reaction time) and there is your future NFL contract. I hope this app finds the next Bolt or Randy Moss.

Thank you so much Quincy! This helps out a lot.

Very good app no issues at, a little hard to get use to timing many athletes at once they need a gap between each other or else it will give one time for two people. Still a very great app for individual athlete sessions either alone or with a coach

The app will not 'deploy'. Turns Bluetooth off then app crashes and turns my phone off. Huawei p9 and s6 edge

Keep crashing my talet!

*Update* had to uninstall. App kept turning itself on in the background, sucking battery life quickly and overheating device. What was it doing in the background?-----I love the idea, and it's definitely worth the price. Causes Galaxy s7 to overheat quickly. Has trouble with multiple athletes finishing close to one another. Would be nice to be able to review recent finish video. Would be nice to have mark, set, and go tones each different. Would be nice to have documentation as well.

Good app but needs a bit of work. Does not work with any of my wireless speakers. The app says they might not have A2DP profile while they all have. My speaker is Sony SRS-XB3.

I Can't get the Wireless Speaker to Connect,I watched the video & did everything right but it just keeps on searching for the speaker,Can you Please Help,Thanks

This application is the best and most cost effective application to sports and athletics. For 99 cents i have nfl combine and usa track timing mechanism accuracy at the touch of a button on my phone. I run track and i will never be nervous for a track meet ever again. I already know accurately what I will run. It makes development more effective because you will always know when you are improving. He has instructional videos that make set up a breeze so if you are having trouble youtube sprint stopper.

Every time tried to use it device started to lag then would lock up. Does not tell you specs to determine if you device is capable of handling

Excellent when training on your own! Who would ever have thought it! Electronic timing at your fingertips, from your mobile phone!

The greatest app for all athletes is so easy to use i ran the 200m with it and worked perfectly ! Now my whole team wants it but I have the only Android phone hopefully y'all get it on IPhone soon this is really going to change sports for ever now that we dont need our coach or friends to time us !

I train on my own and cannot afford expensive timing systems This app is at a great price and records my times accurately without the assistance of another person. Thanks for developing this great app

Working great
