Say goodbye to scribbling splits in heatsheet margins. OttrLoggr will help you take control of your swimming data. No fancy stopwatch needed!
Dive into the toolkit!

Our Philosophy

In order to get where you want to be, you must know where you are now. Awareness is the first step towards improvement.

Practice does not make perfect. Practice makes permanent. In fact, you are what you repEAT!

OttrLoggr handles the numbers so you can handle the laps.

Swim Tech United

Swimmers log their swims at meets and practice in one place. Coaches write sets in their own forums. Parents lookup times and convert time standards in another.

Isn't it time to bring the TEAM together?

We believe that organizing swimming data can be intuitive and enjoyable.

Know Thyself

More Data, More Speed. Go beyond basic splits with...

  • Underwater vs Surface Time*
  • Fatigue Rate*
  • Underwater vs Surface Distance
  • Underwater vs Surface Velocity**
  • Stroke Count
  • Stroke Rate*
  • .. and more!

No Swimmer is an Island.

You shouldn't have to wait 4 years for the Olympics to roll around to get HD underwater swimming video. You shouldn't have to count on the lung capacity of your volunteer cameraman either. We aim to bring affordable camera video tracking to club teams of every skill level.
