I am just curious as to how much book keeping everyone else does?
For me personality since I do re-use alot of my address like a lot of people on here probably do, I have been keeping an excel spreadsheet with 5 columns. First is the Payee/payer if I do have a name. Second column is their address(es) from where the bitcoins were sent or received. Third column is like a memo and 4th is the transaction id. The last column is amount if negative I know I sent it and if positive I know I have received it.
I wrote an iOS app (that is waiting for review) to help manage bitcoin addresses...pm me and I'll give you a free copy when (if) it gets approved. It's called myBitcoin. Hopefully will be available within a week.
You should seriiously consider changing the name of the app.
Just look into the MyBitcoin.com fiasco from last year, and I guarantee you'll not want to be associated with that label in any way.
Apparently I named it myBitcoins (had to check!). I thought about the mybitcoin.com fiasco (crime), but I seriously doubt I will get more than a dozen buyers, if that, no matter what it's called. I wrote the code for myself to use and it does what I want it to do. I am putting it up for $0.99...if there is any significant interest, I will spend time improving it for others (presumably for fellow forum members).
If I were hoping to strike it rich, I would not pick the name (nor such a simple logo).
While I feel bad for those who got ripped off in the mybitcoin.com theft, I remember thinking the whole time it was so stupid to deposit money with some guy no one knows. I think linking a real identity to a username is sorely needed to give Bitcoin more legitimacy, and I think Mike's work with Casascius coins is a great example. I'm also not a fan of announcing stuff in vapor ware style (cough...ellet....cough), but my stuff is done just awaiting the Apple review...and it's no where near as important/revolutionary as what MNW is claiming.
As promised, here's my iPhone app:http://itunes.apple.com/us/app/mybitcoins/id539677499?ls=1&mt=8
It's a buck... That is, until Apple takes Bitcoins.
