Compatible devices
SplendoMonitor connects over Bluetooth to sensors and machines from other manufacturers, and the app makes them work as one system: guided setup, one timeline, one report.
Why it works this way
A traditional metabolic lab is a closed system: one vendor's cart, one vendor's software, one room. It works, and it costs about eight times what the sensors do, which is why these assessments have stayed inside high-performance and clinical research labs.
SplendoMonitor takes the opposite approach. It speaks to metabolic analyzers, heart rate monitors, tissue saturation sensors and ergometers from different manufacturers over Bluetooth, and stitches their signals into a single assessment with one timeline and one report. It also guides the setup of each one, which is what makes a mixed set of devices practical to run.
Everything below is either documented step-by-step in the SplendoMonitor user manual or noted as coming soon. Nothing is listed as supported because it ought to work.
Breathing and gas exchange
Wireless and wearable breath analyzers measure the oxygen consumed and the carbon dioxide produced, breath by breath. This is what makes VO2max, resting metabolic rate and substrate utilization measurable rather than estimated.
VO2 Master Analyzer
Breath-by-breath oxygen uptake and ventilation
Integrated configuration and calibration routines. Ideal for high performance aerobic and anaerobic testing.
Setup instructions in the manualCalibre
Breath-by-breath gas exchange and ventilation
Easy to use use, portable, and accurate. Ideal for field testing and research.
Setup instructions in the manual
Heart rate
Tracks how hard the cardiovascular system is working through the protocol, and anchors the recovery interval.
Polar Verity Sense
Optical heart rate from the upper arm
Setup instructions in the manualPolar H10
Electrode-based heart rate from a chest strap
Reads the heart's electrical signal rather than using an optical sensor, which is why chest straps of this type are the usual reference for heart-rate accuracy.
Setup instructions in the manualMyzone Switch
Heart rate from a chest strap, upper arm or wrist
Can be moved between positions, so one device covers subjects who cannot wear a chest strap.
Setup instructions in the manualAny Bluetooth heart rate monitor
Coming soonHeart rate over the standard Bluetooth heart-rate profile
Support for the generic profile means chest straps and watches you already own, without waiting for a per-model integration.
Tissue saturation
Shows how much oxygen the working muscle is actually extracting, the part of the oxygen cycle that heart rate and breath alone cannot see. Also called muscle oxygenation.
Train.Red FYER
Near-infrared muscle oxygenation, worn on the belly of the muscle
Setup instructions in the manual
Exercise machines
In-app instructions for multiple modalities and automatic resistance control on supported ergometers.
Wattbike Atom and Proton
Power, cadence and full resistance control
Full ergometer control: the app sets resistance for ramp tests, so the ramp runs to the protocol rather than to a stopwatch.
Setup instructions in the manualAssault Fitness Airbike
Power and cadence read out from the machine
Data readout only. The app records what the bike reports but does not set its resistance.
Setup instructions in the manualAny FTMS fitness machine
Coming soonPower, cadence and speed over the standard Bluetooth fitness-machine profile
FTMS is the standard most modern bikes, treadmills and rowers already speak.
Getting the hardware
The software is a flat fee per assessment, so you only pay for what you use. The sensors and machines you buy directly, from us or from anyone else. There is no bundled kit you have to take, and nothing leased from us to give back.
Buy from our store
Our store sells sensors and assessment credits, so a team starting from zero can get everything in one place.
Or bring your own
If your lab, clinic or gym already runs any of the equipment above, connect it and start assessing. Generic Bluetooth heart rate and FTMS machine support will widen this further.
Pay as you go
A flat fee per assessment, so you only pay for what you use. No capital equipment beyond the sensors, and no lab build-out.
Setup is documented
Every supported device has a full appendix in the user manual covering power on, connection, configuration, calibration and placement, sensors and machines alike.
Tell us what you already run
Let us know what sensors and machines you already have, and we will tell you how to connect them to SplendoMonitor.
SplendoHealth
Guided from setup to report
SplendoMonitor connects over Bluetooth to metabolic analyzers, heart rate and tissue saturation sensors, and ergometers from different manufacturers, then stitches their signals into a single assessment with one timeline and one report.
