V U This turns any TV, projector or display with a web browser into a screen you control from your phone. Open vuthis.com on the screen, scan the QR code with your phone (or type the short code), and the phone becomes the remote. Show photos and slideshows, PDF documents with page controls, large text, announcements, clocks in any time zone, countdown / count-up / count-to timers, tally counters, and QR codes for guest Wi-Fi or links. With a pass, items can be queued into an automatic playlist for simple digital signage.
Nothing is installed on the screen or the phone. There is no cable, no Wi-Fi switching and no screen mirroring, so notifications and other tabs stay private: the room sees only what you choose to show. It works on smart TVs, laptops connected to projectors, Raspberry Pi displays and existing signage players, and can be self-hosted on a private network.
Typical uses: meeting rooms and coworking spaces, classrooms and training rooms, shops and reception areas, events and community halls, churches, and family photos on the living-room TV.
Pricing: a free session needs no account (one screen, 60 minutes, 20 photos, one PDF). Passes: 24 hours $5.99, 7 days $15.99, 1 month $32.99, 1 year $299.99, unlocking unlimited sessions, multiple screens, 250 MB storage, queueing, image announcements and all colour palettes.
