What tools are available for multi-variant testing of user on-boarding in iOs apps (ideally that don't require constant re-submissions to App Store)?

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!

Hi, check outmy response to another question similar to yours. I hope it helps. Overall what you need to do is grow your community of users, or depending on the app generate enough sales or interest typically before any investors considering joining you. Not impossible to get investors early on, but your best bet is through kickstarted if anything. My responses tend to get UpVoted by other experts. Check it out https://clarity.fm/a/8032

Top 2 tactics: Existing Users and Industry Influencers. First, leverage the existing user base. Incent referrals with $5 for every new free user they get to sign up and start using PT Engine for a new domain. Second, reach influencers and offer them the same deal when they tweet / post to / email their audiences. Make the offer a 60 day free trial instead of the standard 30 day so that they are providing value to the people they refer as well. This is critical - don't make them feel sleazy, make them feel (and look) like heroes to the connections they share PT Engine with. That's $9k to get 1800 users, leaving you $1k for graphics, referral tracking system, administrative costs. I assume the $10k budget does not include your time - if it does you'll have to reduce the incentive, which will definitely make it less appealing.

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.

It depends a lot of in the skill sets and experience of both people but in most cases the ux designer should be controlling the developer pretty heavily in order to make sure his ideas come through properly. The UX designer may just need to work on his approach so people don't feel bossed around and more like they are working together. In an ideal world, there would be a project manager who makes sure everything is communicated well and keeps the dynamic feeling great.
