About this app

Stopwatch X: Sports Lap Timer was designed for runners & racers but has matured over the last 10 years to be the stopwatch of choice for many more. Time-proven accuracy, robust design, advanced features yet simple! Trust Stopwatch X with your time!

Stopwatch X: Sports Lap Timer is big & easy to use whilst having advanced features such as countdown to start, multiple timers, lap speed calculation, lap time targets with countdown, auto-scaling/adjustable text, side button operation and stopwatch statistics.
This free timer app also has a large landscape view with huge buttons and numbers.


Stopwatch X: Sports Lap Timer has received praise from athletes, engineers, race coordinators and motorsport professionals for reliability, features and a big, clear, simple, easy to use user interface. It has a unique stopwatch feature of five separate recorded stopwatch views so that lap time, split time and statistics, speed and target lap time can be shown separately in large clear numbers. Speed calcualtion can be made made as metres per second (m/s), kilometres per hour (km/h), minutes per kilometre (min/km), minutes per mile (min/mi), miles per hour (mph), feet per second (f/s) and knot (kn). Distance can be set as metres (m), kilometres (km), miles (mi), feet (ft) or nautical mile (NM / NMI).

Stopwatch X: Sports Lap Timer is accurate to 1/1000th of a second, can handle 999+ laps and can run beyond 999 hrs. This stopwatch/ lap timer is one of the few timers available for android that has current lap time, configurable main display, seconds precision and max time duration beyond 999 hours. Stopwatch X can be operated via the device buttons and large display can be locked whilst running to avoid accidental touch events.

As a multi-timer, a maximum of 20 concurrent timers can be running at once. 4 timers are available in the free version, the remainder can be purchased via in-app upgrade purchase for a small charge.
The stopwatch black and white display is large and clear even in bright sunlight, a very important consideration for sports timing such as running, jogging, sailing, cycling and team games.
This Stopwatch was designed as a track timer for runners and athletes & joggers. It has proved to be ideal for many other timing scenarios such as cooking or as a professional session timer.

Major issue with this app. After I registered it (and I can't confirm registration was the problem because the problem is intermittent) this app began randomly activating the volume control. Not only does this disturb music playing on my music app, but the active volume control makes it impossible to click the app's Plus 'button' to advance the lap counter. Tapping the center of the app dismisses the volume control, but it often activates again immediately. You can imagine the frustration as you approach the end of a lap and can't advance the lap counter to record your split ... then pause your exercise while you fight the app to clear the volume control. At first I thought it was a problem with my case. Changed cases, same issue. I used the phone without a case .... same issue. I walked two miles not counting laps with this app (I carried a second phone using a different app) ... no issue. I changed to a different lap counter (without sounds) on the same phone ... no issue. So it's narrowed down to this app. Otherwise, it's a nice app, but this buggy behavior makes it ultimately unusable. Very sad since I paid their price for it and can't use it. I'd love to find that they've identified and fixed the problem so that an update will make the money I spent count for something. 😉

It was great until it started to push with cookies consent. I won't ever give permission, so I rate it with 1*. You ruined a good app with your BS. Uninstall.

Cookie consent is now a legal requirement in many countries. To continue to offer this app free with ads I had to add the one time consent popup. There are options to the reject consent. I will look at the app and make this aspect clearer.

Great app. There are hundreds of stopwatch apps on the store , however most have very little to make them much different from the one you probably get with your phone. This one however allows you to run multiple stopwatches at the same time , each one with all the bells and whistles you would expect from a good stopwatch app like lap times and every statistic you could hope to have. This allows me to do complex exercise routines which rely on an overall main stopwatch / lap timer to track the overall routine whilst then running sub stop watches for different parts of my workout. All in all a great app and I look forward to seeing what new features will be added in the future to continue to differentiate this app from the rest. 5 Star.
