Snapsubmit

The #1 killer of healthy study habits isn't laziness — it's friction

I built an app that immediately puts photos taken on my phone on my computer as downloaded pdfs for easy submission of homework.

Inspiration

Yesterday in my calculus class, many students had problems with submitting their assignments. There was confusion over android vs. apple, and how to submit on schoology, my school's online hw system. My teacher required pdf format, no blur, and found it hard to grade. My friend could not make their multiple photos into pdfs, and he could not get rid of blur and he lost points. In the end it was a strange debate with many different apps and solutions proposed like messaging yourself on whatsapp or middleman. My idea was to make a mobile app where all I do is take a picture of my math hw, and it automatically is saved on my computer and I can immediately submit on schoology
