LipSync Test Tool vs HamSat

Measure - don't guess! Lip Sync is a precision tool for broadcast engineers, live production teams, and OB/streaming operators who need to verify and correct end-to-end AV sync across monitors, routers, encoders, and playout—before you go live or between segments. Key features • Visual & audio test pattern – On-screen markers, beeps and flash cues so lip offset is obvious in control rooms. • Customizable setup – Match FPS and tone frequency to your line standard or show format. • Real-time feedback – Clear Sound early / Video early indicators plus timecode-style readouts in portrait and landscape for quick checks at the desk or in the truck. • Event log – Recent sync-related events in one place for handover notes or troubleshooting during a show. • Latency measure mode – Point a second iPhone (camera + mic) at the program monitor for an end-to-end delay readout in milliseconds and frames. • QR anchor for long delays – Enable QR on the pattern device for frame-guided flash/beep pairing when latency exceeds 500 ms—accurate measurements on high-latency paths up to several seconds. • Live measurement mode – Keep measuring after the first result; the offset updates continuously until you tap Stop—ideal for watching drift during line checks or while routing changes settle. • Measurement history – Recent latency results saved in the Measure screen for quick comparison across runs, formats, or signal paths. • Interface – Dark, minimal UI for dimmed galleries, OB trucks, and fast orientation changes on iPhone and iPad. Why Lip Sync? In live shows and broadcast, sync drift shows up as complaints, replays, and lost trust. Lip Sync gives you a repeatable, end-to-end check you can run on any path—not guesswork in the heat of a production. Ideal for broadcast facilities, live sports and entertainment, houses of worship with IMAG, corporate live events, streaming ops, and systems integrators commissioning live signal chains.

HamSat is the satellite tracker built for amateur radio operators — with an Apple Watch companion on your wrist and, new in 2.1, a sked planner that finds the passes you and another operator can work together. NEW — SKED PLANNER (Pro) • Plan a contact, not just a pass: enter another operator's grid square and find every window where a satellite sees you both • Set a minimum elevation for each end of the link — a window only counts if it's workable at both stations • One tap adds the sked to your calendar with the overlap times, a 10-minute reminder, and the radio setup PLAN AHEAD • Pass predictions up to 7 days out • Add any pass to Apple Calendar — times, reminder, and frequencies in the notes. HamSat never reads your calendar. • Choose your pass-alert tone — including a CW "HI" in Morse APPLE WATCH (Pro) • Your next favorite pass on your wrist: live azimuth, elevation, Doppler-corrected frequencies, and a countdown to AOS • Guided wrist-aim — follow an arrow straight to the satellite and feel a haptic tap the instant you're locked on. Aim your antenna without looking at a screen, hands free for the radio. • Propagated on the watch itself, so it keeps tracking even when your phone is out of range PASS TRACKING • Live sky dome with the satellite's arc and a glyph riding it in real time • Fullscreen Live tracker — big AZ/EL, Doppler-corrected frequencies, landscape split-pane • Aim mode uses your phone's compass to show where you're pointing — no forced figure-8 calibration, just point and go • Apple Maps ground track with horizon footprint OPERATING DURING A PASS • Doppler-corrected RX (and TX for SSB/linear) dial frequencies, updated every second • 10-minute and AOS notifications that deep-link straight to the pass • Live Activity + Dynamic Island on the lock screen, elevation and azimuth ticking live • Bell badge on any pass you've set an alert for ROVER PROOF PHOTOS • Stamp a photo at your site with your callsign, grid, satellite, and UTC time — proof of where you were on the air • Fresh photo or one from your library; share to X, Messages, AirDrop — or submit for the AMSAT Rover Award ALWAYS OVERHEAD (free) • Lists any geostationary satellite in your sky — QO-100 (Es'hail 2) for Europe, Africa, and the Middle East • "Find it in the sky" — point your phone and check your line-of-sight to the bird is clear • No Pro required for geostationary satellites SATELLITE CATALOG • Friendly designations everywhere — SO-50, AO-91, RS-44, JO-97 — with launch names as subtitles • Search by name or NORAD ID • Curated radio data for the most-worked birds, plus live SatNOGS for the long tail — kept fresh by HamSat's catalog service • Filter by mode (FM, linear, beacon, data, telemetry) ACCURATE & OFFLINE • Full SGP4 propagation on-device — the model the pros use, so times and positions match apps like ISS Detector • Works completely offline — every pass, sky dome, ground track, and Doppler computed locally. No API keys, no rate limits. • Always-fresh orbital data via HamSat's catalog service, with direct CelesTrak/AMSAT fallback — or pin a source • Settings shows how fresh your orbital data is PRIVACY-FIRST • Your location stays on-device — nothing about you is sent to any server • Orbital data from public sources (CelesTrak, AMSAT, SatNOGS) • No accounts, no tracking, no ads HamSat Pro — the field operator's toolkit • Sked planner — mutual passes with any partner grid • Apple Watch tracking & guided wrist-aim • Fullscreen Live tracker with second-by-second Doppler (landscape split-pane) • Live in-pass Doppler — corrected RX/TX at AOS, max, and LOS • Overhead-now live tracker for your favorites • Unlimited scheduled alerts — not just three • Shareable Rover proof photos One-time purchase, no subscription. 73 — and good DX!
