Apple no longer allows any app to be downloaded/distributed to devices manufactured in 2012 and prior.
Apple requires all apps submitted to the Apple App Store (including the ShoWorks app) since July of 2015, to be 64-bit. iPads manufactured in 2012 and older, are 32-bit and incomplatible with this requirement. Apple's current policy does not allow any 32-bit apps to be distributed. This is not within the control of any developer, including ShoWorks.
Apple does not allow retroactively seeking an older version of any app to download onto a 32-bit device.

How can I check to see what model of iPad I have?
1) In the iPad, go to Settings>General>About>Model. Tap the "Model" setting to toggle the values where you see a value that begins with the letter "A" such as "A1670". Compare this model number with the numbers above to determine if your iPad is compatible.
2) On the back cover of the iPad in small print is the model number (referenced in the above list). This is often too small to see with the naked eye.
