As with many things, there isn’t an ideal Android device. You have to decide on your own compromise, based on your budget, weather conditions, bright sunlight, temperature (extreme hot and cold), heavy rains and length of your matches.
Nook Simple Touch e-reader from B&N was a popular option, due to a long-lasting battery and a great visibility in a bright sun light. But some users didn’t like slow screen refresh and found infra-red Nook’s touch screen harder to use, comparing to capacitive touch screens. NST devices also don’t have access to Google or Amazon app stores and required some manual setup (aka rooting) to get it running, as well as updating PractiScore app installed on device. This 5..6 years old device also runs 7..8 years old Android version 2.1.3 and it is getting harder and harder to maintain compatibility of PractiScore app with this device.
Wile Nook is still being used, many users choose to use more modern tablets. You don’t need a hight screen resolution, but screen brightness and battery capacity 4000mAh and better are things to look for, as well as Android version 5 and higher, to make sure it will be able to access Google or Amazon app store in the coming years.
Our live app stats don’t show exact device model names, but Samsung devices are leading in popularity. Samsung TabA 7″ 8Gb is a decent one. Previous models Tab4 7″ and Tab3 7″ also worked okay.
The next in the list are Amazon Kindles. The Kindle Fire 7″ is very cheap, followed by Kindle Fire HD 8″. The latter you could often find on sale and it has a bit better screen and better battery comparing to Fire 7″.
