From a general perspective the app developer did a descent job creating an app that allows you to time a variety of tests. However I have three stars because I’m experiencing an odd thing. I need the ability to play the test audio through a Bluetooth speaker and for some reason I do not have this ability with this app. I can play and hear the audio through my phone speaker but if my phone is connected to a Bluetooth speaker there is no audio. I’ve attempted to contact the developer through the available email. I keep getting a message back that the recipient server did not accept the request to connect. I suspect the developer is long gone and has abandoned the app. Just buyer beware.6 months later no response and no Bluetooth speaker support. Has this app been abandoned?

...and reliable yo-yo test app in the iPhone market. Has many test options. Wish it could store info for multiple people at the same time.

Very easy to use! Very easy to switch between tests. Also stores results effectively! You have to do additional research to know which test to use to compare yourself to norms because different teams use different tests. I have found most Pro soccer teams usually use yyirtl1 or yyirtl2. And mostly level 1.

Do not use if planning to test with large teams. Bluetooth volume does not work loud enough to cover large area.
