PDFTrackr's answer:
It's the only PDF tracker that shows you which views were real. Bots and email scanners are filtered out of your counts automatically, and the dashboard shows exactly what it removed. Then Signals tell you who came back and who's worth a follow-up, with a per-recipient verdict on whether a specific person read it, so you act on real buyers instead of inflated numbers.
PDFTrackr's answer:
Most trackers count every open, including bots and email scanners that never read a word. PDFTrackr filters them out and shows its work, so the numbers are real. Then Signals do the analysis for you: who's genuinely engaged, who's worth a call now, plus a per-recipient verdict and real-time alerts with emailed Reading Reports. Full page-by-page analytics are free with a 12-month history and virus scanning, no credit card; Pro is $9/month or $84/year.
PDFTrackr's answer:
Sales and business-development teams, consultants, agencies, and founders raising on a pitch deck. Anyone who sends proposals, decks, and reports and needs to know who actually read them and when to follow up.
PDFTrackr's answer:
Built to answer the question every sender has: did they actually read it, and when should I follow up? Instead of a vanity view counter that inflates numbers with bots, PDFTrackr filters out the noise and turns real reads into a shortlist of who's worth a call.

This is great, thanks for sharing. I'm surprised there are no latency measurement figures whatsoever. Also, not a word about gamepads? Here's one more suggestion for the "Why not use something else?": https://virtualhere.com. - Source: Hacker News / 6 months ago
Still have some things to test like, usb over ip (https://virtualhere.com), and gaming peripherals. Source: over 4 years ago
USB server - for connecting basically any USB device to your PC from a distance. I use a Raspberry Pi 3 running VirtualHere but it's available on tons of devices, I've never had latency issues with it even over the powerline network... Source: over 4 years ago
