A non-coder built a medical study timer with Claude
A medical student with no coding used Claude’s Fable 5 model over a few evenings to build a study timer app. The app is aimed at timed exam practice, especially when pacing through questions matters. A block mode turns 40 questions at 90 seconds each into a 60-minute session, with a circular timer showing time left for each question.
After each block, the user can record how many questions they finished and how many they got right by subject. The app automatically points out the weakest subject and shows a 14-day accuracy trend. It also includes a small always-on-top player for use over UWorld, an exam-day countdown, streak tracking, and .
It needs no account or , works fully offline, and keeps the user’s data on their own machine. To reduce concern about AI-built software, the app is under the , the full code is on GitHub, and it includes an automated .
