## What is Card Decks?

Card Decks is a small utility application for your iPhone and iPad which brings you simple, configurable, colored, multi-line text cards that are grouped into card decks.

A card deck can be used to show your vote or estimation on a certain topic in a meeting, e.g. in a planning meeting used in agile software development methods like Scrum or Extreme Programming. If the pre-configured cards don't fit your needs, just extend the existing cards or build your own set of cards, e.g. including special estimation numbers like "Pi" or "?". Or, if you are the chair of a session on a conference, you can use a card deck to remind a speaker of the remaining time for the presentation. Or, as a speaker, use a timer card deck to track the remaining minutes. Or, just use your cards to show your opinion, argument, or mood, in a simple, non-verbal way. Or, use the shuffle feature to randomly select a task from a card deck with tasks, or randomly assign tasks to students, team members, etc.

Card Decks contains some pre-configured card decks with voting cards, simple colored cards, cards with numbers, colored cards which show remaining minutes, and some timers.

Individual card decks can be created with the built-in editor.

Each card in a card deck can be configured with a display time. This way, you can build your own countdown timer with individual numbers, texts, reminders, etc. Example timers for 15 and 60 minutes are pre-configured.

Additionally, Card Decks supports sending and receiving card decks via e-mail, messages, etc. for sharing your card decks with your friends or colleagues. Either as an URL, or via a JSON-based document.

### 5/5 — A+

*2014-10-31*

This is excellent. the best card deck on the apple store!

### 5/5 — Flexible agile planning cards

*2013-11-04, version 2.2.2*

Card Decks is great for allowing you to define your own set of values for the planning poker game. We use the Fibonacci series up to 13, with ? and pi. More specific agile planning define everything for you, but this allows you to tweak colours, backgrounds, symbols, size and orientation. It even gives you a timed display option to the next symbol, to create a countdown timer. Very flexible; hasn't ever crashed.

### 5/5 — Perfect!

*2012-11-06*

Using this as a Scrum Planning tool primarily, but very useful for group timing, notices, and communication as well.  Well coded, exceptionally functional, and tiny memory footprint!

### 1/5 — but what IS it?

*2012-06-08*

this is a slide show that allows you to quickly set up *simple* slides,and time them as you like, or choose individual slides for display.  I really can't come up with a use for it, though it does seem to be well done.  Sadly lacking in the user info dept, unfortunately.  One star for the programming effort.

### 1/5 — Really?

*2012-01-19*

What is this fOR..?

### 5/5 — Cool stuff

*2011-07-17*

Pretty sweet for being free.  It's basically like creating a small Word doc and saving it.  Plus, it comes with many sample decks that are actually very useful.  Great idea!

### 5/5 — Wow...talk about a great program

*2010-04-24*

A great program....and excellent support. This program is easy to use and works well. I LOVE it. Also.... I emailed with a few questions and concerns and the developer got back to me right away. I see a bright future for this program and the developer. Watch for other great things to come!

### 5/5 — Best planning poker app

*2009-10-23*

Easiest to use. Configure custom card values and colors. And it's free!  Definitely worth it!

### 4/5 — Useful simple App

*2009-09-11, version 0*

Ok, this is what it does. Create card set, add flash cards, show flash card - that's it! When you think about it though the possibilities are endless. We interact now with Red & Yellow cards for the football, sneakily influence colleagues in meetings and perhaps less usefully, a set of expletives!
