How long would it take two developers working full time to create an iOS app like Tinder?

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.

My company does a lot of consulting with offshore firms who are looking for a way to generate new business, so I hear this question a lot. My first reaction is that you need to totally reverse your mindset when you talk about your own company. You mentioned that you have: a great software developers team, proven track record, passion, real value But, everyone says that. There a 10,000 companies that have those things, so a customer isn't going to notice it. You need to figure out what your company is best at (doesn't have to be technical) and present it as a solution to a specific problem that clients have. Maybe a speciality, or really good project management, really good communications, a special expertise or experience, a personality, experience with a certain type of client.. really anything.. But, there must be some thing that makes your company 'special' otherwise you will be lost in the mix. Don't worry about things like rates, or the fact that you have 'great' developers. Those are generic. Think about why a client would really choose you, and try to build on that! After you understand your company identity, it gets much easier to identify and engage marketing channels because you understand your target.

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.

I developed and published mobile apps as an individual for several years, and only formed a corporation later as things grew and it made sense. As far as Apple's App Store and Google Play are concerned, you can register as an individual developer without having a corporation. I'd be happy to help further over a call if you have any additional questions. Best of luck with your mobile app!

I would suggest launching in a foreign app store only (ex: Canada). That will allow you to get more organic users to continue iterating without a big push. I got this idea from Matt Brezina (Founder of Sincerely, previously Xobni) https://clarity.fm/brezina - he's the man when it comes to testing & iterating mobile apps.
