How to know if my app downloads are real or spam?

As the host of 'The App Guy Podcast', I can introduce you to a few good developers ranging from inexpensive locations to $100 per hour top rates. As a quick guess, this type of app will start from $900 using a cross platform solution (Like Titanium Studio) to $5000 for Objective-C apps written on xCode Let me know if you want an introduction by contacting me through my website or podcast Paul Kemp - The App Guy Podcast http://TheAppGuy.co/

Tehcnically speaking the only qualification is the type of development you need. However, if you referring to guideline son how to find and assess good outsourcing partners, you should keep in mind: - speed/quality of communication - previous work - payment/delivery terms satisfy your needs More details can be found here: http://giacomoballi.com/how-to-hire-a-freelancer/

The best day to launch your app is either Wednesday night or Thursday, because the iOS App Store changes features every Thursday and you may get featured that day as "New games..." "New app..." etc. Ideally all your marketing/PR/advertising efforts should start that day (Thursday) because Apple likes it when an app is being privately promoted at the same time it's being featured. Yes AdMob could work for you but please know that there are many other ad placement companies similar to AdMob that can work for you too. You need to see what kind of clients they have, if they match with your niche, etc. Usually this is a trial and error process, you start with several ads and you see which works and which doesn't, you improve, you cut them. etc. Good luck

In my opinion, the best thing to do is to finish the development completetly, test your final product for bugs and when the teating period is over you can go ahead and publish it. Best regards, For more details I'm always available.

I think push vs in-app are two different things, like email and telephone call. Push reaches people who are not using your app, but require OS-level permission. In-app gives you much more flexibility but they only reach people who are using your app (obviously!). As to whether in-house or external SDK is best, it depends what you are trying to do and whether an external system handles it. For a typical retail environment the SDKs might be easiest--it's a well-established use-case. For something needing a more customized algorithm, an in-house system might work as well as an external SDK (for less money). There are simple options to save you from starting completely from scratch, from PHP toolkits to Amazon SNS. It depends on what (if any) server environment you have... Hope that helps!
