This app is extremely too expensive for what it is. This app could use more social connections. More questions. And much more for $10. Beatable in a couple days.

I am sure you are possibly in the works of this already.

Please add more levels!

so you can get lots of new apps soon .. how can I wait for them???

It would be great of the game linked with others playing the game and learning.

I would like to be able to see the children's progress and them see mine.

That or link so you can have friends within the application.

Thanks, I look forward to your future updates.

Hei hei! 5-åringen min er ferdig med DragonBox2; noen mulighet for at dere lager en mer utfordrende oppfølger? :-)

It should say "You have mastered..." not "master."

I you have x + i/f = d - 5, it would be great to be able to subtract i/f rather than multiplying by f and dividing by i. I know this isn't taught in the 5+ version, but would it be possible to make it allowable anyway?

Make it possible to make your own avatar. I don't like any of the offered ones. The avatars are all dark and disturbing if you want more parents to go for this make the images more kid friendly.

Our school is looking into replacing our expensive and hard to manage laptops with Chromebooks. App availability is somewhat spotty, though, and I see DragonBox as the main headline app, so it would be great to have it available. (Or better yet, an HTML5 version so we don't have to worry quite so much about platform.)

Just a grammar fix for the last congrat's page.

Perhaps do a new power thing, showing that dragging a to -a turns it into the spiral galaxy. Many kids would probably intuit it, and get there by trial and error, but showing it like I said would help kids with difficulty with abstraction, or those who hadn't been introduced to negative numbers.

When you finish all the worlds, enable an in-app purchase that has for instance 20 new worlds. Purpose: makes the kid practice more. I would be happy to pay 1-2 dollar per world.

Level 5 should be able to slide the negative one die on top of f to make it -f (and combine) before moving to the opposite of the equation. Level 5-17?).

Level 5 - perhaps in addition to double clicking to clear 1/-1 or object/ opposite object fractions (which seemed random at points because we couldn't tell which one to click to make it turn over consistently), students could combine the number and its opposite to get a negative one die or -1.

I'd like to be able to make my own levels, to use for solving problems from other sources, for instance. It would be a great way to work through a problem before solving it on paper.

If a student enters a color piece when a b&w should have been entered, they get stuck.

It is great that you have plans for release on Windows Phone. We hope that it will be available soon. Thanks!

Where the fractions are object/opposite object or night object/object could have it turn into a dark 'one' die so that students can understand it can be -1 instead of not able to simplify.
