I have this app and another on my iPhone but haven't used either of them yet. I understand it's quite a drain on cell phone batteries. Don't have an iPad.
You can buy an external battery for smartphones for $20-$30.
To me, it's invaluable. Primarily because my smartphone is a battery pig, but also because I'm not always in a position to charge my phone before going out for the night. The external battery isn't any bigger than the phone itself, I set the phone on top of it, plug it in, and it tops off the phones battery quite nicely. The model I have isn't one of the fancier models, and I can get two phone charges from it before it needs recharging itself. It resides in the long pocket of my cue case...
On the topic of discussion, as a newbie to 14.1, I have found that keeping score is challenging. There aren't any beads to be found in our part of the world, and only one room has tables with the scoring wheels built in. (I don't play there except for 8/9-ball league nights, due to it's cost and the condition of said tables.)
We keep score on a piece of paper. We also have small chalk boards on the wall behind each table, but I prefer to not have to stay standing the whole game, between playing and scoring.
I am quite sure I don't understand the protocol and procedure for scoring 14.1. Does the shooter keep track of his own, and then add them to the beads/wheels, or is it the sitting players responsibility? If it's the shooter himself, doesn't that require your attention to be in two distinct different "modes", playing and keeping track?
Thanks for your patience with the newbie. I think I'm gonna investigate the smartphone app, though the one guy I play with will very likely not be open to using it...
