What is the cost to acquire users for an iPhone game app?

NASA is famous for writing the most bug-free code in the history of programming. They do it by being fanatics about test-driven development. They write tests for tests. If you want to have a rock solid app, you have to put everything else aside and focus only on quality. Every time a new build goes out, every single member of the team has to test every tiny nook and cranny and write tests to mimic how they're testing it in real life. The goal is to start small with a solid core and get it functioning error-free before building other features. If you hold yourselves accountable to make feature incredible before you begin building others then you'll never have to go back and clean up something later. In short, try to do it "write" the first time :)

Well, the biggest cost here wouldn't be in the app, but in the server infrastructure. As usual with connected apps, people often forget they have to be connected to servers. The app itself is just a view to what the servers provide, so it's not the major cost. 20K $ to 100K $ should be enough. On server stuff, I expect it to be a lot more, particularly if you aim for a wide audience (several million $). On a Whatsapp clone, I'd consider: - solutions for performing calls through servers, not that easy. Look at what Twilio provides. WebRTC is an upcoming protocol that will ease that (web & mobile). - solutions for API, IM and user accounts management. Look at StackMob or Parse which are MBaaS (Mobile Backend as a Service). Hope it helps!

Re-visit your marketing strategy. Which is to say - re-visit your business model (which should very directly point you in the direction of your highest probability marketing strategy). And (get ready to not like me for saying this...) stop focusing on those numbers. The number of visitors per month and the number of downloads are only relevant as they directly relate to conversions and sales. And those things are only relevant as they directly relate to bottom line revenue and margins. It's easy to get caught up in "vanity numbers"... those numbers that "feel good" and provide you with a sense of validation. But until and unless they translate into bottom line income for the business they are just numbers that make you feel good (versus wisely chosen key metrics that indicate the health and viability of your business). If this was helpful to you please let me know how else I can be of assistance.

Hi there! Best of luck as you complete your college degree. From experience I will try to give you some insight into the world of startups and mobile apps. First some things to consider: 1. You live in a world of social klout 2.Apps must (specially iOS) must be very well developed, otherwise the users themselves will filter you out. 3. Apps must be relevant if you want to succeed. You've have probably seen this, a lot of paid apps go for free for a while when their sales begin to stall or never actually make any pay back to the developers. Free is an easy way to get users and thus paid advertisements or in app purchases (if they are good enough to keep) Assuming you will have all 3... Let's move on to your question: Most investors won't entertain an idea alone, specially if you haven't any prior successful experience in running a startup or app development company. Some do however, consider depending on your social klout, learn about growth hacking and consider growing your social relevance before the completion of the app. As mention by Ryan Holiday, a blogger not too long ago got investment for a book from a simple screenshot of his followers' requests for the same topic... he decided to write a book and through his community market it. This was a no brainer for the publisher investor. With that said, an often unspoken rule of networking is that you don't ask for favors in your first intro. You don't do that in your personal life, you shouldn't do that in your professional. Make friends in the right place, build relationships with a backbone in honesty, mentorship and through time as they see you work and guide you they themselves begin to entertain the idea... In the future, when you ask, your chances are much better that way. Get yourself a team, find a developer to mentor you and help you improve as you learn. Most new entrepreneurs think that their product at launch is their "final-good enough for a while- product" and is not! Complete opposite, you must realize that your initial launch is nothing more than the 1st iteration of the many to come if you want your community of users to stick with you and share their experiences with others as you help them and improve their lives by listening to their suggestions and issues with your app. If you have a developer this will become easier in the long run as well as tell an investor that you are capable of being a leader, even if is of 1. Best of luck, give me a call if you wish to talk a bit more :)
