Giftster (iOS, Android) is most useful if you're organizing lists for groups of people, like families, friends, or offices.

There's also a Secret Santa feature that makes gift exchanges easy.

What about a present for you this holiday? Gift yourself Gifted (iOS). It has plenty of organizing and budgeting features, including letting you make profiles of those you're buying for so you always have their sizes and preferences on hand, setting budgets per person and per event, keeping gift histories so you don't rebuy the same gift for someone, and telling you how close you are to accomplishing all your buying.

Divvy up the dough you have to spend by who you're spending it on with The Christmas List (iOS). You can also arrange your list by store so you don't make multiple trips in person or fill online shopping carts (and pay shipping fees) more than once. If you're sharing gift-giving duty, there are simple ways to send your lists. The countdown feature lets you know how many shopping days you have left this season.

Same name, different app. The satisfying ticking off of items is probably going to be your favorite feature of Christmas Gift List (Android). Or you might prefer that you can get a countdown to Christmas, keep track of your budget, and even start planning for next year.

It would be nice if Santa showed up, but you know there's not going to be a Christmas miracle. You're buying the gifts this year and Santa's Bag (iOS) can help you keep track of what each person wants, how many gifts you've purchased, how much to spend, and even if you've wrapped the gift or not.

Don't write in your diary wondering how you'll get everything done for the holidays, use it to get your gift list under control. Gift List Diary (Android) lets you set a budget for everyone on your list, mark when a gift is bought and when it's wrapped, and lets you share your lists with others.

Buying and budgeting is made easy with Christmas Gift List (Android) this year—and next—since it archives your list to remind you of the favorite items of your favorite people.

There's a countdown to Christmas at the top of Christmas Gift List Tracker (iOS), not that you necessarily need one if you're on top of your gift giving to the point of using an app. What you can probably use, though, is the bar chart with your budget that's right underneath. It tallies up all your purchases from your various gift lists and lets you know how much you have left. The app also lets you view lists from previous years to avoid gifting mistakes, collaborate on lists, and set a password so no one can snoop.
