Stopwatch & Lap Timer - Advanced Sport Chronograph is easy to use whilst having advanced features such as multiple concurrent timers, speed, target time, countdown delayed start, target time countdown, auto scaling/adjustable text, side button operation and time statistics.

Stopwatch and lap timer has received praise from engineers, race coordinators and motor sport professionals for reliability, features and simple user interface. It has a unique stopwatch feature of three separate recorded timer views so that lap time, split time and statistics can be shown separately in large clear numbers. This free timer app also has a large landscape view with huge buttons and numbers. Recorded lap times and total times can be resized using a two finger pinch/expand gesture.


Stopwatch is accurate to 1/1000^th of a second, can handle hundreds of laps and can run beyond 99 hrs. This stopwatch and timer is one of the few timers available for android that has current lap time, configurable main display, seconds precision and max timer duration greater than 99 hours. Stopwatch can be operated via the device buttons and main display can be locked whilst running to avoid accidental touch events.

Key Design Principles

Clarity
The stopwatch black and white display is large and clear even in bright sunlight, a very important consideration for running, jogging, sailing, cycling and team games. The lap timer has multiple screens views accessed via a horizontal swipe and large buttons. Whilst this stopwatch is ad supported, we only use a single banner at the bottom of the screen so not to hinder the display. We don't use video ads or full screen ads. Ads can be removed for a small charge by upgrading.

Accuracy
Stopwatch and timer operates precisely to 1/1000 second via on-touch actions (not on-press). Nearly all other stopwatches for Android operate on press... these timers are not as accurate since a press can take up to 1/3 second and yet a touch is instantaneous. It has configurable precision and time correctly recorded in milliseconds as point measurements.

Reliability
This free stopwatch app is designed correctly with point measurements of system time to the device storage so that timer sessions will survive in the background, screen lock, app closure and even system restart, updates and re-installation.

This Stopwatch was designed as a track timer for runners; however we feel it is also ideal many other timing scenarios such as cooking or as a professional session timer. Stopwatch & Lap Timer - Advanced Sport Chronograph has been popular since 2012 and has had over 2 million downloads.
