Real-Time Audible Velocity Feedback in the Metric App

Real-time feedback gives you audible cues during your set so you can react to bar speed during your set to inform intent and rep count. Configure it on the recording screen via the megaphone icon.

Four feedback modes are available: Read, Target, Velocity loss, and Tempo.

Read

Announces the score for each rep — typically velocity, however you can also use ROM, power, time to peak velocity metrics.

Pick the metric to be read out when you toggle Read on. Use this when you want a performance check across the set without setting any thresholds.

Target

Sets a goal value for your chosen metric. Reps that are above the target play a chime while reps that fall below will play a buzzer sound.

Configure the target value when you toggle Target on. If historical data is available Metric will show your 6-week average performance for that exercise and weight to give you a guide as to an appropriate personalised target. Alternatively, you could set a fixed target value to keep your training in the appropriate velocity zone.

Use this as a motivational tool when you want working sets to stay above a target speed. For example, power on your cleans must stay about 1000W or the set ends. Or for strength sets that must end at 0.4m/s to avoid working into too much fatigue during a tapering phase.

Velocity loss

This feedback type will stay silent until your set approaches your target velocity-loss threshold as calculated from the fastest rep of the set (e.g. 20% loss).

Stays silent until you’re within 5% of the threshold, so the cue only fires when it matters. When you cross the threshold, the alert helps guide you to perform one more rep, or to end the set early.

Tempo

Plays a 1-second metronome through the recording to help you control eccentric, pause, and concentric timing. Tempo metronome can be played alongside the other feedback modes allowing you to control your eccentrics with the metronome and then push your concentrics with the guidance of the other feedback modes.

Use this for controlled eccentrics or paused reps. See Tempo metronome for the full feature.

Why use real-time feedback

• End the set at the right exertion. Velocity loss mode handles this without you watching the screen.
• Train with intent. Target mode keeps every rep above a goal speed.
• Pick the right working weight. Reps too fast above your target, add load. Too slow, take some off.

When to leave it off

• Technique work — internal cues only, external noise is unhelpful.
• Warm-ups — light loads, the cues are likely noise unless you are performing ramp up sets approaching your work weight.
• Max-effort singles and doubles — already locked in, feedback adds an unnecessary distraction so we recommend leaving it off.

Toggle your feedback controls from the recording screen before you record.

Audio output

Cues play through whatever audio output your phone is currently using. Pair Bluetooth earbuds for in-set cues in shared gyms. Volume follows your device’s media volume.

Feedback values vary from post set data

Metric runs its object tracking analysis twice for every recording. Once in real-time and once immediately post set. This is part of what makes Metric so accurate but it also creates small variations (1-5%) between the real-time feedback values and the post-processing data. When in doubt trust the post-processing data as the second pass strengthens validity for your data, and understand that the real-time data may be slightly slower or faster than the final values for each rep.
