Date of data collection: 28th of October 2021
Metric has been in development since late 2019, went into a private beta November 2021 and launched publicly for iOS in April 2022. In that time we have made and continue to make big jumps in both validity and reliability of our ability to track and report training data for barbell lifts.
While external validation is yet to be published (research underway), we have completed a range of internal validations, the largest of which was the publicly available motion capture comparison linked here.
On the same day of this data collection, we collected data from both a Vitruve and Gymaware linear positional transducer unit out of curiosity. These results are contained below and have not been published.
We are pleased with these results, showing our technology to be an accurate and reliable option. However, accuracy is not our mission.
Metric aims to drastically improve the user experience when training with velocity. from collecting data, provide live feedback, recognise trends and make meaningful interventions into a program. To do this the focus is heavily on ease of use for the app, data analytics and insights for athletes and incorporating coach feedback into future feature development.
I (Jacob Tober) performed all sets on the data collection day, using 40kg for all three movements; a Conventional Deadlift, Front Squat and Bench Press.

Each exercise was performed for two (2) sets of eight (8) repetitions. The first set at a slow movement speed (TEMPO) while on the second set the participant was instructed to perform the concentric portion of each repetition as fast as possible (MAX).
A total of 48 repetitions were included in the study across six sets.
