Hi!
Just went through some habit apps and yours is so much better than any other I've tried. I like your on-boarding so I don't miss any feature.
UX/UI design looks cool. Actually everything is perfect.
But. As it was mentioned above sometimes it looks a little bit creepy, so it's only my perception, I can't explain rational reasons.
The Sphere part is confusing. I don't like when the product has another product. I want to install an app that I can fully use and don't want to think that I have no access to some of it's additional features.
And the part '' writing commitment contract'' freaks me out, I've never tried it, as it looks creepy.
I like the idea of having strong community and being a part of it. But I think for me (I'm writing this review after 1 hour of using it) it was too energy consuming to go though everything and reading all the text and so on.
