Small apps I've built for classroom and personal use. ## Exam timer https://app.joshuacussen.com/exam-timer/ I made a prototype of this a few years ago and then rebuilt it using Claude. ## Interval timer https://app.joshuacussen.com/interval-timer/ I own a sit/stand desk and couldn't find an app that did endless interval repetition for sit/stand reminders. Built using Claude. ## Progress colour calculator https://app.joshuacussen.com/progress-colours/ A tool to calculate grades based on historic grade boundaries, scaled to work with shorter assessments. It also generates 'progress colours' which my school use to indicate progress relative to baseline attainment. Built using Claude.
