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

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!

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

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/

Hi, I had an entrepreneur ask me this same question recently. Based on the information Apple Provides you can definitely enroll with a DUNS number. There is a difference in the process of enrollment but both sole Proprietors and Organizations can enter. Here's a quote directly from Apples on business procedure. "Sole proprietors/single person businesses can review the license agreement and purchase a membership at the time of enrollment. Organizations can review the license agreement and purchase a membership once Apple Developer Support verifies the enrollment information and sends an email with next steps. You can check the status of your enrollment in your account on the developer website. Be sure to sign in with the Apple ID you used to enroll." Hope this helps. Feel free to request a call with me, I wouldn't mind helping you analyze the situation so we can streamline you on your way to the answers you need.

Apple specifically precludes anything that can't be delivered via the app from using in-app purchases. So you're free to tie a credit-card to services and real-world fees (think Uber) without paying Apple any transaction fees. Here's Apple's documentation on what they support (and don't allow) for in-app purchases. https://developer.apple.com/in-app-purchase/In-App-Purchase-Guidelines.pdf Happy to help in any way I can. I run a mobile-based startup myself.
