So far, it shows promise
I’ve been following In/Out when this was just an idea. Happy to say, it shows tons of promise. With the obvious bugs that will plague this app and the In/Out device, I’m very excited to see the continued development of this app and the In/Out device. I’ve seen great improvements in just these few recent updates. Thank you for the hard work and dedication! Please continue improving the apps and the device. Hopefully we’ll have some great improvements before Springtime, when tennis starts to go full-swing.
