This app is legit. If you need to follow lines. This is the one.
Easy. Fast. Configurable. Options. Dont see how you can pass this one up. I use on an iPhone. You can display totals, lines with totals, etc. See both current and opening lines. I have checked all the apps out. This is my go to one. Will even do alerts.
