Any books or online platforms that will aid me in building a mock app that is user profile based?

There are two sides to that question. One is the mobile app itself and the other is the backend. If I misunderstood in any way and you didn't mean "native" app I apologize in advance. On the backend, there is no clear cut answer to which is the "best". It depends solely on the developers you are able to get. We for example use Node.js , mongoDB, redis, elasticsearch and a couple of proprietary tools in the backend. But you have your pick of the litter now both on the backend api and the datastore with the myriad of options available and touted as the "best" currently on the market. Now on the app side again it solely depends on what you need your mobile app to do. Experiencing first-hand "develop once, run anywhere" I can say it's more like "develop once, debug everywhere" to quote a Java saying. We have tried Phonegap and Titanium Appcelerator and we have switched to native (ObjC and Java) after a couple of months of trying to go the hybrid route. The reasons behind the choice are as follows: - anything that breaks the pattern of how those frameworks NEED to operate is just a huge technical debt that keeps accruing a huge interest. - anything that uses css3 accelerated animations on Android is buggy at best and slow as hell at worst on any lower (< 4.1 I think) versions of Android I hope this gives you some insight. If you need/want to ask me anything feel free to contact me. Mihai

The ways I've done this in the past are 1) Find some customers that are willing to hire you (or your product) but know that you'll only be free nights & weekends to support/work with them. 2) Find a "partner" (co-founder or other) that's got a flexible schedule that can help build the business while you're at work. 3) Block out nights, mornings and weekends to build the business till you have enough orders to cover 50% of your salary. This might mean 7pm-11pm most nights, and 4 hours each day Sat & Sun. Make progress (sales $$$) and momentum. All that being said, it's risk reward. Sounds like you want to avoid taken the risk, and I get that .. but the upside is always smaller. Unless you put yourself in a position to have to succeed (ex: quitting your job) then you may never make the scary decisions that are required to build a company (like cold calling, going in debt, making a presentation, etc). I'm on company #5 with many other side projects started nights & weekends .. so I get it - but don't be afraid to bet on yourself and go all in.

You won't find anyone worth adding to your team willing to work for equity only, no matter how compelling your product and business is. The realities of the talent market for mobile developers anywhere is such that a developer would be foolish to work only for equity unless they are a cofounder and have double digit equity. Happy to talk about hiring and alternatives to full-time hires.

You are right that the range is wide. You need to figure what are good values to have for your category. Also, you can focus on the trend (is your DAU/MAU increasing vs decreasing after you make changes) even if benchmarking is tough. Unless your app is adding a huge number of users every day (which can skew DAU/MAU), you can trust the ratio as a good indication of how engaged your users are. For games, DAU/MAU of ~20-30% is considered to be pretty good. For social apps, like a messenger app, a successful one would have a DAU/MAU closer to 50%. In general most apps struggle to get to DAU/MAU of 20% or more. Make sure you have the right definition of who is an active user for your app, and get a good sense of what % of users are actually using your app every day. Happy to discuss what is a good benchmark for your specific app depending on what it does.
