Drop2sync currently just supports Dropbox and Box. It’s written to be extendable, but each cloud service has its own (usually very different) user interface. Is there one you’re particularly interested in?

I’m glad drop2sync is working for you and that you like the wallpaper!

Sadly, the Kindle system is pretty much locked down. Whatever you purchase from Amazon.com is stuck forever on Kindle devices or the Kindle app. Whatever you purchase from Barnes & Noble is stuck forever on Nook devices or the Nook app. You can’t load the Nook app on Kindle Fire, and you can’t load the Kindle app on the Nook Color or Nook Tablet. It’s possible to load protected EPUBs purchased from other sources on the NOOK, but that’s about it. Sorry to be the bearer or bad news.

Take care,

Is there a way I can take my book from kindle?

I also have your wallpaper keep up the great work, hope more apps are coming

Thanks for writing! I understand the situation you’re describing. My kids did that until I added the stars, score-keeping, and the perfect game rainbow/applause. Lately, I’ve been thinking about ways to detect the “press any button” thing. Do you think showing the number of incorrect guesses would motivate your daughter? Any other ideas about what might motivate her? I’ll definitely add your idea to the suggestions list, and I’ll continue to work on ways to discourage random guessing. If you think of anything else, please drop us a line at suggestions@WhitneyApps.com or leave another message here.

I’m afraid that drop2sync can’t get around Adobe’s ADE-only restriction on library books. Drop2sync can sync purchased books once the NOOK is authorized b but it doesn’t work for borrowed books. It’s necessary to use their software to do it. I recommend contacting Adobe for help with ADE. They’ve been able to help some others. I’m willing to help as I can, but my knowledge of Adobe Digital Editions is limited (pretty much to what’s listed on this page).

If you can’t get help from Adobe, feel free to post another note and we’ll see if we can come up with a couple of things to try.

Take care,

Thanks for writing. We’re furiously learning iOS development right now. There are a couple of apps in the pipeline, but if there’s a need for CardDroid Math (and a market), we could possibly do it later in 2012. Of course, we’d have to change the name. Apple’s not too fond of the little green Android

If there are specific things that you like about CardDroid Math that you’d like to see on iPhone/iPad, please email us at suggestions@WhitneyApps.com so we can put them on the future possibilties list.

Thanks again for writing, Darren.

Take care,
