I am trying to figure out a way/service that allows me to call out from our business phone number, from my iPhone. Can anyone help?

Optimizely is a popular testing service that lets you do this. See: https://www.optimizely.com/mobile/ and http://developers.optimizely.com/ios/

My experience with online communities is mixed. Those work best if you have a value proposition that appeals to a large mass for a short period of time - i.e. a game. For something like healthcare I'd imagine you are looking to have people engage regularly and for an extended period of time. That is going to take more time to convince people to use your platform. You should be looking for your core user. If you developed personas and user stories, you can use those to identify groups to start with and expand from there. A beta test with a few hundred core users is better than 1000s of users that don't fit your model. If you didn't develop personas or user stories, I'd recommend taking time to go back and think through those. Either way, I'd be happy to help you get started. Best, Brian

If I had to pick a single efficient and affordable way of getting in front of a targeted audience I would have to recommend Facebook in-stream ads. You control the budget, the target group and the message and they are, right now, offering the highest conversion rates for mobile apps. Keep in mind that your app needs to be amazing - that's the most effective strategy of all...

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 :)

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.
