Hi. I have a free app called Georeader, MyGeoReader: Hear as you near. Learn as you go. The app reads aloud to you roadside markers and other things as you pass by them when you drive. I have been putting together a business plan as the iphone version of the app is almost done. I am reserving a budget for marketing. I am curious if anybody here, as a developer, have used a paid app advertising agency to help them. I have attached an example of their claims below (this one is from Apalon) . I was curious if these firms are effective use of marketing dollars and if , as a developer, you were pleased with the results if you used them. Thanks Dave Here is what they claim...... $3,999 GUARANTEED RANKINGS Pre-launch: 5-7 business days * Post-launch: 12-15 business days Services listed in Premium plan + increased traffic from ads across network of our apps.
