App onboarding walkthrough
Screens captured from the PrO2 app—from role selection through training. Use the arrows, scrubber, or keyboard ← → to move at your own pace. Optional autoplay pauses while you hover so you can read.
Choose your role
When you open the app, pick how you use PrO2—healthcare, fitness, research, and other options tailor the experience.
Select a role
Tap the role that matches you. Your choice helps the app show the right workflows and terminology.
Role highlighted
The selected role is highlighted so you can confirm before continuing.
Continue
Proceed to the main app once your role is set.
Open Training
Move to the Training area when you are ready to measure or train—not just assess.
Training tab
The Training screen is where you connect the device, pick modes, and run sessions.
Device connected
With Bluetooth connected, the app shows the device is ready for a session.
Start session
Begin when you are positioned and sealed on the mouthpiece—follow on-screen prompts.
Choose mode
By default, only full breath inspiratory training is available.
Confirm mode
Review the mode and confirm so the app can configure targets and feedback.
Mode ready
The app locks in your selection and prepares the breathing task.
Optional tutorial
Step-by-step guidance is shown until skip is chosen.
Ready to train
When setup is complete, you will see a clear “ready” state before the first breath.
Baseline breath
A baseline breath establishes today’s reference for training.
Baseline in progress
Keep steady effort; the display updates pressure, time, and power in real time.
Baseline complete
At the end of the baseline breath, you can accept or recreate if needed.
Baseline accepted
With baseline saved, training loads can be scaled from today’s performance.
Training set
Training breaths use live feedback—aim for the target band or line your protocol defines.
Training in progress
Continue through the prescribed breaths; rest intervals and prompts guide the session.
Rep complete
Completed breaths are summarized so you can see how each rep met the goal.
Session winding down
If effort drops below the failure threshold, the app begins to end the set safely.
Fatigue reached
Training stops when targets are missed—this protects quality and reflects true fatigue.
Performance Warning
If your effort falls below acceptable levels for the session, you will be asked to stop training so you can recover safely and keep quality high.
