Just wanted to let everyone know that my new, fully featured all-grain homebrew application "Brew Pal" is available for free on the iTunes app store... it will run on both the iPhone and iPod Touch. This is a big update from Sparge Pal, my first app (Brew Pal does everything Sparge Pal does and a heckuva lot more!) Please see http://nurl.knowfear.net/iphone/brewpal
for more info on the current version.
There are BIG changes coming that will address the most common complaints: lack of grain and hop data! The next version, which is under review by Apple now, will have predefined grains with points and lovibond (hence automatic SRM calculation) AND predefined hops, so you can see your estimated IBU.
Sparge Pal will always be free, but Brew Pal will be $0.99 starting next week.
Thanks to everyone here that bought Sparge Pal!
EDIT: I've subscribed to this thread, so I'll see any questions or comments you post here. Also, please feel free to contact me via the link on the Brew Pal website! Hope this doesn't sound like a sales pitch, I just want to get the word out and make sure that everyone who bought Sparge Pal gets a shot at Brew Pal while it is free.
