Logipace - proven in a controlled clinical trial* to instantly improve athletic performance, an average of 45 seconds on a 3-mile run, with significantly less stress on the body.
***Full Version supports real-time Wahoo Heart Rate Monitor (ANT+) for maximum performance benefit.***
Cardio-Locomotor Synchronization (CLS) occurs when a rhythmic activity is performed in sync with the heartbeat.  Some examples include running, biking, walking, or dancing.  CLS has been shown in many published studies to increase efficiency, improve heart stroke volume, reduce blood pressure variability, and lower maximal oxygen consumption.
Logipace uses CLS with an advanced patent pending algorithm to enhance performance of any rhythmic activity, and lower the stress on the heart and musculature.  The app records heart rate real-time using the Wahoo Heart Rate Monitor (ANT+ Interface only at this time), determines the optimal pace frequency within a comfortable range that best matches a harmonic of the heart rate, and plays one of four different beats at that precise frequency.  By matching that beat, the user is using the power of CLS to perform better and make the activity easier on the body.
Synchronization between rhythmic activity and breathing has also been shown in numerous published studies to have significant benefits both to performance, but also to reduce stress on the body. Logipace uses Respiratory-Locomotor Synchronization (RLS) along with CLS to maximize efficiency and minimize the impact from strenuous exercise.
Logipace is very simple to use:
Define a comfortable range - Set the max and min pacing frequency (in steps per minute) that will still allow you to maintain your desired speed.
Define a comfortable breathing cadence - Based on your paced stride rate, set the number of paces for breath inhalation and for exhalation.
Heart Rate
Paid app - Establish a connection with the Wahoo Heart Rate monitor (ANT+ version only at this time).
Free app - Enter a target heart rate that you expect to maintain during the run.
Start a session and begin exercising - match your pace to the beat as close as possible.

Abstract:
Cardiolocomotor synchronization (CLS) has been well established for individuals engaged in rhythmic activity, such as walking, running, or cycling. When frequency of the activity is at or near the heart rate, entrainment occurs. CLS has been shown in many cases to improve the efficacy of the locomotor activity, improving stroke volume, reducing blood pressure variability, and lowering the maximal oxygen consumption (VO2max). Instead of a 1:1 frequency ratio of activity to heart rate, we investigated if another simple integer ratio (e.g., 1:2, 2:3, 3:2) could achieve similar performance benefits. We designed an algorithm that determines the simplest ratio (lowest denominator) that, when multiplied by the heart rate will fall within an individualized predetermined comfortable pacing range for the user. The algorithm was implemented on an iPhone 4, which generated a tick-tock sound through the iPhone’s headphones. We performed a sham-controlled crossover study with 15 volunteers of various fitness levels. Subjects ran 3 miles at their normal speed on two consecutive days (randomized one active pacing, one sham). 84% of runners decreased their run-time during active pacing, with an average 35 second decrease across all active subjects, showing a significant reduction compared to sham (F=5.46, P<0.04). Rise-time of the heart rate from the beginning of the run until the heart rate reached steady-state during active pacing was significantly reduced compared to sham (t = 5.77, P < 0.001). 87% of runners found it easy to match their footfall to the pacing signal. 79% of runners thought pacing helped their performance.
