Better BAC

[thoughtcriminal]

***The newest version (0.9.3 as of this writing) is available as a Beta Application. I do not plan to upload this or any future version as homebrew.***

Right now, it's in private beta (not in the RSS feeds), but if you're reading this, you're welcome to download it.

If, for some reason, you really want this version as homebrew, let me know and I can upload it.

Special thanks to everyone who downloaded my app here, and to Precentral for hosting it.

Below is the information on the last homebrew version:

Better BAC
This app calculates and keeps track of your estimated BAC in real time. Add the drinks you've had, and the app will do the rest!

Download this app in the PreCentral Homebrew App Gallery

Features

• Real-time, always updated BAC estimate
• Calculated time until BAC is at the a predefined limit
• Calculated time until BAC is at zero
• List of drinks that are still "in your system"
• *NEW* List of drinks that are no longer in your system going back a predefined number of days or drinks
• *NEW* Graph your BAC over 24 hours, or through all your saved drinks!
• *NEW* Add drinks from any time in the last 24 hours
• Tap a drink in your list to "have another" with the same volume and abv
• Swipe drinks to remove from list if entered in error
• Two calculation methods: Widmark or Watson (experimental)

This program is licensed under the GPL version 3.

This program will always be free of charge. I made this app for fun, not for profit. If you appreciate this app, then give your cab driver or designated driver a few extra bucks.

All values calculated by this program are estimated.

Moved "Add drink" to footer and added "Graph" button in footer

Version 0.7.2 (unreleased)

Added "Add a drink" button between the status box and the drink list
"Graph drinks" menu item renamed to "Graph BAC"

Version 0.7.1 (unreleased)
All drinks are in a single list
List is divided into current/history by a divider function
Drinks at the top are the newest drinks
Drinks may be graphed (all or 24h)
Time to zero/limit is displayed as #h #m instead of just total minutes
Added history preferences (max days / max drinks)

Version 0.7.0 (unreleased)

Features planned for the next version

• Put "Add drink" in floating footer
• Add popups for feedback (on invalid drinks etc)
• Add alarms on reaching limit/zero (can be turned off in prefs)

Known Issues

• Due to rounding, the total of the individual drink BACs do not always equal the total BAC. This is only a display issue. The internal numbers are correct as far as I know.
• I might have screwed something up with the Watson calculation. It gives reasonable values, but it doesn't seem right to me. It would be awesome if anyone who is good with numbers (especially unit conversions--that's where I get confused) and wants to take a peak at the source (if you can't read code, but still want to help, just let me know and I'll write it all out for you).

To do someday

• Allow manual setting of Widmark constant
• Save "favorite" drink templates

Sorry you were having trouble with your posts.

I had to remove some of the links, but they're in my quote of your post below.

Hopefully it's up now.
