This app is really great. This is like a hidden gem for O level students who need to do a lot of past year Question papers. The multiplayer feature is very smart, and I like it a lot. Thank you to all the developers, I hope the server for the A level app will be up and running for the next 3 years as I will start my A levels.

The Story Behind Paperstack
Built by a student, for students.
Salman
Founder & Developer
As a Cambridge student, I experienced the struggle of exam prep firsthand during my O/A Levels. Scattered resources, no easy way to check my answers, and no accessible quality app to find past papers.
I started building Paperstack as a weekend project in my room during my O Levels in 2022. Invested hours of my time in it, kept improving it through my A Levels, and when I got the chance to focus on it fully during my gap year, I not only improved it but added insanely cool features which I had longed for back in my time but didn't have.
Today, it's used by 50,000+ students across 50+ countries and I get messages from students all over the world about how helpful this app has been for them.
Every feature in Paperstack exists because a student asked for it. From AI-powered grading and quick scan explanations, to topical question filters and Multiplayer Matches with friends. Features that no one could have thought of and none of the other platforms currently offer. Only yearlies but free topical latest papers for IGCSE, O & A Levels. I've kept this app free and invested in it with my own money. This app is shaped entirely by the community it serves.
I'm the only dev behind it and your support matters to me to keep this mission alive.
