About Unique AppSites
A learning brand that also builds apps
Unique AppSites is a learning-content brand associated with Anubhav Goel, featuring engineering and computing explanations, revision content and useful digital tools.
The lessons live on YouTube, organised unit by unit and explained clearly enough to revise from. The handwritten notes follow the same order as the lessons, and the Telegram group keeps everyone up to date. Fold, the Unique AppSites app for Android, handles the documents students and working people deal with every day.
