Watch Tuner Lite measures the accuracy of mechanical and automatic watches. It uses the built-in microphone or headset microphone to record the audible tick of the watch and calculates the seconds-per-day deviation. Works with almost any 'ticking' watch/clock. Use in a quiet environment. Any ambient noise can affect the accuracy of the results. Complete silence is best. Recommended way to record the ticks is to touch the crown of the watch with the headset microphone. You will get the best results using original Apple EarPods. This is a simple version of Watch Tuner application. Not everyone needs detailed information about a watch movement, sometimes only accuracy is important. Watch Tuner Lite uses very similar algorithm like Watch Tuner does but displays only seconds-per-day deviation. If you want to know how much your watch is fast or slow, this application is for you. If you prefer to measure also beat error and amplitude, try Watch Tuner - a bigger brother of this app. If you need frequency diagram look at Watch Tuner Timegrapher - the most sophisticated app of Watch Tuner series.
