iOS Onboarding without Signup Screens
Sebastian Kreutzberger

I agree, this has a ton of potential to improve onboarding and retention for apps. Di-Ann Eisnor was just giving a talk on @platzi about growth, citing a stat that ~68% of users delete an app because of the sign up process (second only to annoying notifications). Great work and thanks for posting it!
