Velocity based training and jump height fitness app

Train with precision and accessibility: all you need is your phone.

NEW! Velocity Based Training and Jump Height with your
Apple Watch

Spleeft has arrived to your Apple Watch.
Track barbell velocity and jump height from your wrist.

Visualize the data in real time on your iPhone.

ACCURACY IS A MUST

Accuracy is a must. Spleeft showed a high correlation (r>0.95) when compared with a linear transducer.

A scientific validation and field data available.

The Apple Watch showed very good accuracy against a motion – capture system. Independent scientific validation available.

Read our validation post to see the good inter-device reliability of our algorithms against a linear transducer.

Training autoregulation

ATHLETE INDEPENCE

Spleeft compares today’s best rep. Velocities with your historical data and gives you a score about your daily performance. Also shows you your estimated 1RM based on an automatic load – velocity profile. load – velocity profile and the optimal loads to train.

Real-time feedback

THE MOST POWERFUL

Stop each series after reaching a certain value of velocity loss (fatigue). Enhance your performance trying to beat last rep velocity.

Long-term tracking

TRAINING LOAD

Control if your performance has improved after a training period or you have to make some changes to achieve it.

Made by coaches for coaches

For Personal Trainers

MEASURE JUMP HEIGHT

Resistance training is not just lift weights. Put your phone on your arm and measure squat, drop and countermovement jumps (SJ, DJ and CMJ) height.
The algorithm is not definitive and will be improved in the future.
