If you run (or are pricing) the Just Jump System, Plyomat reads the same vertical jumps with precise modern hardware and a free app — and includes a Just Jump mode so your testing stays familiar. Contact timed to 0.001 seconds. No subscription, ever.
The Just Jump System has been a fixture in weight rooms for years — a contact mat wired to a small timer that reads an athlete's flight time and reports a vertical jump height. It is simple, proven, and a lot of coaches learned to test on it. That heritage is exactly why a modern Just Jump alternative should feel familiar, not foreign.
Where the original stops at a number on a handheld display, today's coaches want the data to keep going: into a roster, into season-long reports, onto a leaderboard the team can see. They also want reactive metrics — contact time and Reactive Strength Index — not just height. Plyomat is the modern upgrade. The Controller 3.0 times ground contact to 0.001 seconds across 8 assessment modes, runs about two weeks per charge, and connects to the mat by cable. Every result flows into the free Plyomat 3.0 app instead of disappearing after the rep.
It is the same kind of testing you already trust, with precise hardware, real software, and no recurring cost as a Just Jump replacement.
Results land in the Plyomat 3.0 app the instant they happen — roster, reports, leaderboard, and a live display on iPhone, iPad, Mac, Windows, or web.
Ground contact timed to 0.001s unlocks Reactive Strength Index, flight time, and a full reactive picture. Learn about RSI →
A dedicated Just Jump mode keeps the testing workflow you already know, so the switch from the Just Jump System feels familiar on day one.
One Controller, many screens. Run testing from a phone on the field or a Mac at the desk — the app is the same everywhere.
Durable polyurethane switch mats in 28×14″, 28×28″, and 27×36″ — connect up to four portable mats with 2m cables.
The app is free for hardware owners — no subscription and no per-athlete fee. Buy the hardware once and the software stays free.
The same vertical-jump testing you trust — with precise hardware, a free app, and reactive metrics the original never produced.
