Weight Watchers and some other programs calculate points using a well known algorithm that combines Calories, Fat, Fiber to obtain a point value. My wife wants a new blackberry but can't live without this app... Anyone... Anyone...?

saw this thread in the developer forum. go down towards the end of page 2

Awesome. Thanks!

That's what I'm sayin.....! Outstanding tool, thanks.

Loads and looks great however it does not take in account fat or fiber; the algorithm is flawed :(

If you are the developer please check!!!!!!!!!

The mysterious Weights Watchers calculator is 50 calories = 12 grams of fat = 1 point. Each gram of fiber reduces the point total .2 points or 10 points.

For the mathematically adept, calorie = 0.02 pt, fat gram = 0.083 pt, and fiber (g) = -0.2.

If not mathematically adept, my apologies. If you're eating even halfway heathly, it's almost all based upon calories (if you're eating something with 12 fat grams, you're not likely watching weight too closely). Add up calories, subtract 10 calories for each fiber and add (roughly) 4 calories for each fat gram, and then divide by 50 (add a "0" on the end and divide by 2) to yield your points.

pretty sure i implemented it fine, but it's not the same as the poster above, if anyone has a link to an algorithm i'll double check. the formula i used can be found here: http://encyclopedia.thefreedictionar...atchers+points

if this is incorrect, anyone can tell me what it should be and i'll rectify:

caloriesInt = Integer.parseInt(caloriesField.getText());
fatDouble = Double.parseDouble(fibreField.getText());
fibreDouble = Double.parseDouble(fibreField.getText());

if(fibreDouble >4){
fibreDouble = 4;
}

pointsDouble = (caloriesInt/50) + (fatDouble/12) - (fibreDouble/5);

is there a list somewhere of amounts and their corresponding points value i can test against somewhere?

edit: i've tested the above code with the data here: http://www.healthyweightforum.org/en...tchers_points/ and it works fine for everything but the quarter pounder with cheese, anyone spot the error? what the formula doesn't take into account is rounding, by comparing and contrasting it seems that to reach the final points you massivly round up...

edit2: read the above code snippet.... major error!!!!!!!! the fibre field is getting read twice.... i'll do a new build today, that's what you get when you copy 'n' paste code....

Looking forward to seeing this final build!

here you go, new build:

Talk about customer support! WOW!

no kidding! great app!

Thanks Jon!!!

I'm pretty new to using a BlackBerry and can't get the link to work from my Blackberry to load this app. How do I load this?

you have to download it to your desktop then...brace yourself...use the desktop manager's application loader to put it on your BB.

what about a program that tells you how much points yo have eaten in a day, based on a predefined list of foods. Similar to what ascendo fitness does but based on the weight watchers points system and will export to a spreadsheet so you can track your points. This would be very helpful for me!

Hello,

I've downloaded and have started using the points calculator - Thank you

Does anyone know of any program that will keep track of your daily points, calculate excercise points and has the point values for food as well ?

WW has on the go but do not support BB's so I'm trying to find a alternative.

I would like the same type of app which will make keeping track of points much easier.

Any developers out there that would be able to do this, it would be greatly appreciated by many individuals I am sure.

Aww, I'm feeling left out.

Where is the LA Weightloss tracker.

Here, I know. Self restraint.

*ducks and runs*

I think that went over my head.

Somebody please create this, we can't have those guys with their Palm devices laughing at us because this app isn't for the blackberry! As well we have to keep the blackberry cool and if they have the app and we don't we will be getting fat, j/k

Much appreciation, once again, if anyone takes the time to create such an app.

Marc from Ascendo here. I'll try to address a few points with 1 post.

Ascendo Fitness allows you to export nutrition and exercise entries via email. Nutrition entries includes calories, carbs, fats and proteins. You can import them into an Excel spreadsheet or other app that accepts CSV or text delimited formats. From there, you could create formulas to calculate points.

We are listening and have added a "point system" to our development roadmap for Ascendo Fitness. We will look into licensing the Weight Watchers and other point systems.

We currently record daily nutrition and exercise entries and provide totals & graphs. You would like the same thing for points, right?

Thanks Marc for listening, really appreciate it. I have downloaded the trial of your fitness application and have been pretty impressed with it. I like all of the functionality but just am not sure I will have the time to manage all of the information that can be added and output from the application. This is the reason for me asking about the weight watchers point calculator. If your app had that as well I definitely would purchase it. That way I could easily know how many points I have taken in, in a particular week as well as watching my carb, fat, protein ratios.

Once again, really appreciate your listening to us asking for this.

FYI I have also been trying out your money software and it seems fairly good as well. Want to test a few more things before I splurge the money on it. Once again a lot of features and all I am looking for is an expense tracker. Great work you guys are doing, keep it up!!!
