I haven't seen a single project that looks like this one. I don't think there are competitors.

It would not be very good if someone could see the information. I think here full confidentiality. Maximum - users will see your email.

Yeah, you're right, but what about customer support or issues resolving? Whom can I contact in case of dispute with expert or if failure of the application occurs?

WhenHub Interface Network integrating scheduling, geostreaming, video communication and Ethereum smart contracts to make the world’s first time-based knowledge monetizing ecosystem.

There's some information about team:

Yes, that is Scott Adams, creator of Dilbert, one of the most iconic and famous comic strips in the world. Like me, he is also a co-founder of WhenHub and to-date has invested $2 million in the company.

We are very proud to share our work with the world. We are a very small, but highly efficient team. That's how we roll in Silicon Valley where most of us are based. I am in Mountain View (otherwise known as Google HQ town).  :-)

Please see today's blog post by CEO and third co-founder Quin Harker that talks about how we are building an ecosystem:

that number of downloads is definitely intriguing if it is a real number.... 

Quite easy to verify: https://etherscan.io/token/0xf4fe95603881d0e07954fd7605e0e9a916e42c44

Every 500 token transaction represents an app installation. Since our app is geared towards ordinary consumers who have no knowledge of crypto, we wanted to reduce friction so we built a wallet right into the app. We call is WHEN Wallet...it's generated on the user's phone and the user is asked to save the mnemonic. Immediately, 500 WHEN tokens are deposited into the wallet so that the user can start making calls right away.

The smart contract has special protections (source code at link above) so the signup tokens can only be used for calling Experts. They cannot be transferred out. Once they are used to pay an Expert, he/she can transfer them out. This is all logic built into the smart contract.

I'll go dig up the App Store and Play Store analytics and stick them in a blog post...probably good for PR anyway.

But, rest assured, if we post a stat, it is very real. We have hard-earned reputations and we are not about to squander them by posting untrue information. Thanks for listening (er...reading).

I agree with you. By the way, the second app Approach is also updated regularly, and it also has quite a large number of downloads, isn't it?
