Live heart rate
See every lane at once
Heart rate comes in over an ANT+ broadcast, so one receiver picks up your entire squad. No per-practice pairing, nothing to drop mid-set. Every card lights up in your team's own zone colors, so you can see who is hitting the set and who is sitting on it without walking the deck.
An ANT+ USB stick, one ANT+ sensor per swimmer (a swim-friendly optical armband works well), and Chrome or Edge on a laptop. That is the whole setup.
Why coaches switch
Three things coaches tell us they can't get anywhere else
Your team's color chart
Most systems lock you into fixed zones and colors. Here you build your own: the bands, what you call them, and a color or gear number for each. Set it once for the whole squad, and the deck reads in the language your swimmers already hear on the wall.
Set it up once
Link each sensor to a swimmer once, walked through in the app. After that every swimmer is recognized automatically, session after session. No re-pairing before a set, no roll call.
Bring your own sensor
Runs on standard ANT+ heart-rate sensors. A swim-friendly optical armband worn on the temple or forearm works well. No proprietary unit, and nothing you have to buy per swimmer.

What apxswim does
The deck math you use daily, and the HR system built around it.
The calculators are open to everyone today. Everything heart-rate below is in private beta.
Calculators
Pace, splits, critical swim speed, race pace, and a tempo tapper. Quick enough to use between sets.
Live HR over ANT+
One receiver hears your whole squad at once. No per-practice pairing, no dropped connections.
Custom team color chart
Build your team's own zone chart: the bands, their names, and a color or gear number for each. Most apps hand you fixed presets and expect you to adapt.
Athlete cards
Each swimmer's HR trends, zone-time history, and attendance in one place.
Roster & groups
Add each swimmer with a name and age range, sorted into training groups. Nothing else to fill in.
Attendance, automatically
Attendance comes from who logged heart rate that day. No clipboard, no extra step.
By a coach, for coaches
Built on the deck, not in a boardroom
Built by Coach Wes, a swim and performance coach at Charger Aquatics in Albuquerque. It started as the calculators he needed at his own practices, and grew into the heart-rate system he wanted on the deck.
