We launched AppToolkit.io earlier in the year and it's now breaking $500 monthly. Since we use it in-house, we don't judge it quite the same as if it needed to support itself. It isn't profitable yet, but as more app developers sign up for our Super User and Cloud Config service, we're seeing faster revenue growth.
Our original goal was to cover the AWS bill and pay for all the in-house dev work and I think we'll have that by the end of the year.
So the apptoolkit.io SDK is out of beta and ready for production use.
With it you can edit your app code remotely without a resubmit - Cloud Config - and segment your users into your Super Users and everyone else.
Super Users lets you not only see what your users are doing while they do it, but also lets you target just those users within your app. So instead of asking every user for an app review every 10th time they open the app, only ask your super users. They're much more likely to give you a positive review anyway.
I wrote an article about how segmenting your users by the how often they open your app and how long they stay in it is one really good way to be able to target different groups in your app for engagement.
You only need the three cars if you insist on owning the vehicle you're riding it. So if Mom, Dad and Kid all need to be somewhere different at the same time, Uber Pool could work for two of the three, or all three while the car is earning more as Uber Black (or the future equivalent). They only need their own vehicle if they want to ride together.
