### 1/5 — Try to purchase but it’s none purchasable

*2025-11-04*

Three option all shows 0.00$ and when I click it, nothing happens. So then I download jump2 instead how the problem can be resolved soon

### 1/5 — Reseña

*2025-10-08, version 5.0*

Dudas con el funcionamiento de la aplicación, escribo pero no se responden los emails. Se me colgó varias veces casi terminando un test incremental, tirando el test por completo… el potencial uso de la app es la leche pero si no se ayuda a usarla bien para mí no tiene sentido pagar por algo que no me da ninguna función. Tampoco he podido  medir la fuerza en dominadas porque no me detecta el ejercicio y no sé si es que coloco mal la cámara o que, los tutoriales son demasiado escuetos. Si la app funciona me parece un error que no se instruya al usuario que la utiliza…

### 1/5 — Malo

*2025-07-24, version 4.7.4*

No sirve la cámara y eñ algunas mediciones no da, tengo un iPhone 11pro, en fin

### 1/5 — Inconsistent

*2025-07-02*

I have a 29 inch standing vertical. I have a standing reach of 95 inches and can grab 120 inch rim standing easily. The app does not give me over 23 inches vertical unless I grew 6 inches overnight the app is very wrong

### 1/5 — Lots of errors

*2025-05-09*

The linear doesn’t exist, just gives you curve data.

It gives totally incorrect times, it tells me a 5 sec sprint is 35 secs

The zoom function on the videos is terrible, you can’t track video 

There is no tutorial on the linear sprint 

With this many user issues i can’t recommend it

### 5/5 — Great app for sports scientists

*2025-04-02*

This is really a good app for every athlete, coach, sports scientist. As a matter of fact, I wrote my Masters exam submission article measuring vertical jump performance using this app and in another project. I submitted research proposal to further validate and understand reliability of this app which is good.

### 5/5 — super App, super Service

*2025-01-23*

Ich nutze die App regelmässig, im Unterricht und im Verein. Wenn man gerne schnell Daten zur Sprungkraft (SJ / CMJ/…) erheben will ist das eine super alternative zu Kraftmessplatten usw.
Falls man Probleme hat wird man innerhalb kürzester Zeit, bei mir war es keine Stunde kontaktiert. Das Problem wurde auch dann sehr schnell gelöst.
Die Daten kann man mit verschiedenen Geräten erheben und auch abrufen. (iPhone/IPad/Mac)
