What It Is

Spleeft is a professional training app built for Velocity Based Training (VBT), available on iPhone, Apple Watch, iPad, and Mac. Its core pitch is “one device for planning, measuring, and analysis”: you can use an Apple Watch or iPhone to track barbell velocity in real time, and also measure jump height for squat jumps, drop jumps, countermovement jumps, and similar movements. Strictly speaking, it is not a general-purpose generative AI tool, but rather a vertical AI/intelligent application centered on sensor algorithms, sports data analysis, and training decision support.

Core Capabilities

The product focuses on real-time velocity feedback, velocity loss control, load-velocity profiling, estimated 1RM, long-term training load tracking, and performance trend analysis. The website states that its measurements correlate with linear position transducers at r>0.95, and also mentions good accuracy when comparing Apple Watch data with motion capture systems, suggesting some level of scientific validation. Its coaching features are also fairly complete: users can create multiple athlete profiles, sync data via iCloud, import planned workouts from TrainingPeaks, and bring in CSV data from other VBT devices through an Action Extension.

Pricing and Trial

The captured content clearly shows a 3-day free trial, and mentions special pricing or conditions for clubs, professional teams, and high-performance centers. However, specific pricing for the individual, PRO, and Coaches versions is not disclosed, so long-term cost transparency is only average.

Pros and Cons

The main advantage is the low hardware barrier: velocity and jump monitoring can be done with just an iPhone or Apple Watch. It supports 200Hz measurement, multi-platform sync, and multi-athlete management, making it a good fit for coaching workflows. The limitations are also clear: it is heavily tied to the Apple ecosystem, with no visible Android information; the jump height algorithm is described as “not definitive” and still subject to improvement; and details around an open API, Chinese-language support, payment methods, and training data privacy are not fully disclosed.

Who It’s For and Access from China

Spleeft is best suited to strength and conditioning coaches, personal trainers, online coaches, sports teams, and high-performance centers for implementing VBT, managing remote athletes, and monitoring training load. Access from mainland China, network stability, and payment methods are not explained in the main text, so they should be considered unknown. If Apple services, TrainingPeaks, or overseas payment methods are involved, real-world testing may be needed. Comparable VBT solutions include MyLift, Vitruve, GymAware, Perch, and Output Sports.
