How to increase downloads of my "Counting Numbers" app from 1000/day to 3000/day.

We have created this 'Count Numbers' free game for preschoolers to teach basic math skills like counting numbers, write numbers, understand greater smaller concepts, connect dots, and more. Initially we were doing 200 installs / day which has escalated to 1000/day. Now we are planning to take it to 3,000 / day.

Any ideas ???

Hey, maybe you can try put your apps on more app stores, or try some mobile ads. network to advertise for your app?

You will need to introduce some incentive system.
By sharing via facebook or inviting friends, unlock levels, add features or win monthly price. Every app needs motivation system and incentives are good way to go.
I did that with an app for a bank, connected to Facebook game, which was meant to educate local customer about products and cultivate future bank members through playing set of games, dealing with gold investment , loans and credit card points. As a result we managed to accumulate 70k participants in 4 months. Pretty much your regular MLM scheme.
As for prizes, we were giving them away on Friday , so people would talk about it after work, while hanging out with friends.

I think your game looks nice, but you need to refine the illustration a bit. Other than that, I have no other comments.

Best of luck!

By the way, as said by Vivian, try fb ads. They are not very costly and not super effective, but you can specify your exact market target group, which will help. It gave us about 15% more participants in total.
