Intervelocity

Intervelocity gives you insight into your workouts over time. Compare your performance for periods of time (7, 30, 90 days, etc)
Other apps and services might show you how you compare to prior months, years, etc but Intervelocity is different. Rather than track a month, for example, we track the most recent 30 days. Your data is always relevant rather than only towards the end of the month or if a month has fewer days. We show you the most recent periods and the three prior periods for greater insight.
Using the data you already track in the Health App you can compare distances, times, number of workouts and calories burned.
Track progress for walking, running, cycling or hiking workouts.
Works with any app that reports data to the Health App.
Optionally set and track your goals.
All your data remains private and no account is needed.
