Whistle
Plan practice on your laptop. Run it from your phone at the mat.
I built Whistle for my own practices. My plans lived in one place, my timer lived on my phone, and neither one knew when we were running long. Now one app holds the plan and runs the clock.

Plan mode: timed blocks, drills and notes
Run mode: readable from across the room
Plan in blocks
Build practice as timed blocks like warmup, technique, live and conditioning. Add drills and notes to each one. The end time updates as you plan.
Run it mat-side
Hit Start and your phone becomes a big, simple timer you can read from a few feet away. Skip or go back without losing time already spent.
Know if you’re running long
A small ring shows how far over or ahead you are, measured from when you actually started.
Works without signal
Wrestling rooms have bad service. Whistle keeps working offline.
Built by a coach
I’m Ben Rosen. I run youth wrestling at Beat the Streets Chicago and use Whistle mat-side at my own practices. Every feature started as a problem I had in a real practice.
Whistle is in beta on iPhone.
