[Watch App] Shopping with Pebble - Shopping list watchapp with after shopping statistic, and more...

Shopping with Pebble

Basically a shopping list application for the Pebble, with list creating, and one-by-one completing functions for everyday shopping. At now with the current SDK the application needs to be open during the usage, cause after exit(pressing the back button any time) all the list element will be lost(With later update will be fixed if the SDK gives us the chance to use some of the memory, or with a phone application), if notification appear(eg. phone call) it's not a problem, because after you vanquish it the Pebble backs to the application without any problem.

Usage:

At the Main List - Up/Down moves the pointer and scroll the list if the total sum of the goods greater then what the screen can display. Select short press cross out the actual object. Select long press opens the Menu.
At the Menu - Up/Down navigation. Select short press selects the actual menu point. (New - Opens the new item selection sub-menus. Delete - Deletes the actual object. Replace - Replaces only one object with another one if needed. Delete all - Deletes all the list element, what is now equal with exit, so later it will be useful. Back - exit from the menu)
At the Category selection menu - Up/Down changes the category. At now there is 5 category [Vegetables and Fruits, Meats, Grains, Drinks, Others], later it will be more, eg. Household items and such things. Select button selects the actual category.
At the Product selection list - Up/Down navigation. Select short press adds an item. Select long press add an item to the Multi selection, after it you can add all of it with double click on the Select button. You can go back from the actual list with the Back at the bottom of the list.

If all the items are crossed out, a new window pop up where you can decide to go back if it was a miss press, with the Bottom button. With the Middle button you can view the after shopping statistic, with the total sum of the items, and the average item/minute, and also with a diagram of the shopping that shows the bought items / minutes. (I'm planning to modify if the total time more than 5-10 minute the statistic changes to 5 min intervals, cause now its a bit hard to read after a long shopping) With the Upper button you can start a new empty list.

Before anyone start whipping about the statistic drain the battery, it not. Maybe you can think that that's implemented with minutely refreshing/ticking, but it's not. The time always logged if you cross out an item, and not every minute, so at the analyzation point the empty minutes calculated from the logged minutes.

Later plans:

-Adding list editing/creating functions on the phone with the later SDK, and another program that runs on the phone.
-More categories and more items/category.
-Make statistics better view after 10 min shoppings.

That could be a long wait.

I don't mind. Before I spend an hour to create a shopping list on my Pebble, I'll just grab a piece of Paper, write the items down and tape it to my wrist ;-) it's not as cool, but definetly has a better time to use ratio ;-P

With a bit of practise it would be quicker than writing them.

Actually its pretty easy to construct a new shopping list, with multiselect you can quickly add more than one item in one time, to only restriction is the list limited to 20 good, what is necessary because no-one want to overload the pebble with too much data, it can keep more, but I think it's a reasonably limit. And the paper also don't tell you that how much time you spend with shopping, and where was the idling during the shopping time. When the new SDK comes out with the phone<-->pebble data sending, I'm planning to make a more interesting shopping behavior analyzation, such as monthly, weekly, yearly statistics, most bought item, and a new category that contains the mostly bought goods, to make it more quicker, and much more. Also with the phone+ version it will obviously more faster to make a list. But now it's not an hour to make a list with pebble, it's easy to search an item, because it's ordered alphabetically in 5 main category, so it's more likely around 5 min.

And the most important reason to use it: Cause it's GREEN, no paper needed to make a note, what you put in a bin after shopping.

ok, you convinced me, I'll give it a try :-)

But is it worth the time ?

Nice work. I am looking for something like this.

Making a shopping list may seems to be a Routine Task, but it's not. Every time you construct a different list due to the actual needs, some thing you buy weekly, some thing you buy monthly, and another things yearly. And without a shopping list you may buy something that you do not need, what makes more expense, and time is money, due this if you spent more money without a list you waist more time, and also without a list you may forget something. 

And you also have to consider that if you read possibility, it makes less time than if you have to think what you need, during a list making. 

With this program you do not need to much time to make a list.

I assume you know that you by now can have data persistence by using Katharine's httpebble [https://github.com/Katharine/httpebble-watch] library. Among other things (Internet access, location, time zone etc.) it adds a persistent key-value store.

Yeah, it's a nice idea. I'm still working on it, but I have finals at the university, so between 2 exam I will be release the new version with the phone app.

@SzathmaryDominik any plans on an updated version? Like the app and am looking forward to more functionality.
