I think that you should consider white labeling. Or perhaps not necessarily white labeling, but releasing SDKs to allow to use the platform from third-party apps. Obviously many app developers and companies could benefit from having it available from their own apps.
I can also see value for it in the academic world. Academia is starting to dip their toes in the crowd research and this could be very valuable. But again, I don't see a benefit to actual users to download the human.io app, it seems as an unnecessary hassle. Having it available from other apps allows third-parties to offer their own benefits.
