We love index cards. We use them a lot.

They are a versatile and surprisingly powerful tool for all kinds of tasks. From brainstorming or flash cards, to storyboarding and planning entire projects, they have a place in your workflow.

Jot down ideas or sketch diagrams on cards and arrange them on a large board.

Use cards to capture individual ideas, sketch diagrams, or type detailed notes.

+ Training

Could Be Great; Not There Yet

Man, I'm so conflicted. I really want to encourage these developers to keep improving this app, but I just don't want to pay for something that just isn't there yet.

The app works and there are a lot of gerat ideas here, but it is seriously lacking in much needed preferences, especially for formatting (line spacing, tabs, bullets). Additionally, the user experience is sadly lacking. For example, when you open a new card and start typing, your cursor is immediately way up in the top left corner and you can't place the cursor somewhere else with your mouse. There is no Magic Mouse support.

Biggest issue of all is printing. There seems to be no easy way to print these cards for analogue use. Yes, there are work arounds, but none of them easy.

Finally, I really do hate paying subscription fees instead of buying an app outright. I know that's where the business is going, but it's not my preference.

No Free Version for Desktop - Can’t Use Unless You Commit

Looks like a silly little basic app which would suit my purposes just fine - downloaded the desktop free version to give er a whirl. Boom - no way of even creating a single card - just an advertisement for the paid version which is an automatic $2 per month straight on your itunes account even if you hate it, it will automatically charge you until you go into your itunes account to cancel the subscription. If you are a few days over - tough crap! they keep the money for the whole month - all this just to see if this silly little app will even work for what you need it for! No thanks - there is no free version - its just an app you install that is an advertisement for the auto paid version. Don’t download this until they are up front about it being a paid app only.

Great app. Lots of potential

This app has so much potential. The ipad version is fantastic. Great tool to manage your thoughts into chunks for sorting and selecting. The only thing that bugs me about the mac version is making the cards bigger and moving them around. I wish there were a size you could choose that would stay put. When you try to move or resize you have to work too much to get it at the right magnification. Otherwise, well done app that syncs well across devices...
