User reviews

Good app

Good app however maybe there could be more customisation. I also despise the robot voice maybe you could’ve used the Olympic voice? And make the get set say just set. Other from that good app.

Response from developer

My apologies for the long delay in responding. Thank you so much for your feedback! I'd love to know more about the customizations you'd like to see. Please reach out here or at https://www.warmwindssoftware.com/contact. I will address the "Set" call - thank you for mentioning that; I will honor the standard. And regarding the voices - I'm at the mercy of iOS and watchOS's built-in speech synthesizer. Again, thank you!
