About

WorkProof is a desktop tray app that helps freelancers prove their work to skeptical clients without sacrificing privacy.Every 10 minutes it silently takes a blurred screenshot and logs which app was active. At the end of the week, one click generates a professional PDF "Proof of Work" report showing active hours, idle time, app breakdown, and a grid of blurred thumbnails.Unlike TimeDoctor or Hubstaff (which are built for employers to spy on workers), WorkProof is built for the worker. Everything stays local — no cloud, no subscriptions to a server, no data ever leaves the machine. Users own their data completely.The app is fully working on both Mac and Windows, with adjustable blur levels, a date range picker for reports, and a clean system tray UI that stays out of the way while you work.The business model is simple: $5–9/month per user or a one-time $29 license. The payment layer (LemonSqueezy or Paddle) is not yet integrated but requires less than a day's work to add.
