About Pocket Screen
Pocket Screen makes separate, resizable live reference views of supported Mac app windows—PDFs, documents, browsers and dashboards—so you can keep a source in sight while working in another app. The original window remains where it is. Keep two views free for repeated 10-minute sessions, with no trial expiry. Optional Unlimited supports up to four views, no session time limit and Ultra quality. Runs on macOS 14+ on Apple silicon and Intel.
