Thanks for the feedback! Our only concern of framing this post is to guide the basic structure of the education app development. We are not miss-leading our readers, instead all our time projections and cost estimations are based on various surveys.

As far as the estimated development time of sign up or registration process is the concern, we have provided an average time to build this feature.

For more info, you can go through this survey report, submitted by Clutch 2015, where you will get the full breakdown of the app development stages as per the different complexity level. Survey Link: https://clutch.co/app-developers/resources/cost-build-mobile-app-survey-2015

According to this survey report, the development hours to create user logging feature is starting from 4.5 to 70 hours depending upon the complexity of the app.
