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! ## Key features - Apple Watch companion for pass tracking and antenna aiming - Live sky dome with real-time satellite arcs - Aim mode with phone compass and haptic feedback - Doppler-corrected frequencies for operating during passes - Photo stamping with callsign, grid, satellite, and UTC time - Offline satellite tracking and propagation - Geostationary satellite tracking ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | HamSat Pro | $9.99 | one-time | ## Frequently asked questions about HamSat ### What is HamSat? HamSat is a satellite tracker designed for amateur radio operators. It provides real-time tracking of satellite passes, including azimuth, elevation, and Doppler-corrected frequencies, with an Apple Watch companion for wrist-based aiming. ### Does HamSat work offline?

No Pro subscription is needed for this functionality. ### How accurate is HamSat's satellite tracking? HamSat uses the SGP4 propagation model, which is the same model used by professionals, ensuring that times and positions match other reputable tracking applications. It also offers multi-source TLE data for comparison. ### Does HamSat have ads? No, HamSat is ad-free.

This indicates a recent update, suggesting ongoing development and support for the application. ## Version history (last 5 releases) ### 2.1.4 — 2026-08-18 Cleaner satellite names. Birds now show their compact OSCAR designations everywhere — AO‑7, UO‑11, TO‑108 — instead of long launch names, with the catalog name kept as a subtitle. Suggested by an operator; keep the ideas coming. 73! ### 2.1.3 — 2026-08-17 A fresh look on the App Store — new screenshots showing everything HamSat does today: 7-day pass planning, the sked planner, calendar export, and the frequency catalog. Plus small housekeeping under the hood. 73! ### 2.1.2 — 2026-08-15 Passes, day by day. The Passes list now groups under day headers ("Saturday, Aug 15"…), so planning across the week reads like a calendar — no more hunting for where one day ends and the next begins. Requested by an operator planning POTA activations. 73! ### 2.1.1 — 2026-08-08 Sked planner refinements — from operator feedback the same day 2.1 shipped: results now group by day for easy week-ahead scanning, and a new satellite picker lets you plan skeds for one specific bird (or favorites, or everything). Keep it coming — this app is built from your requests. 73! ### 2.1 — 2026-08-08 NEW: Sked planner (Pro). Plan a contact with another operator: enter their grid square and HamSat finds every window where a satellite sees you both — with each station's pass peak, your own minimum-elevation bar for each end, and one tap to drop the sked into your calendar. Pairs with 7-day predictions to plan the whole week. Requested by operators like you. 73! ## More apps by Vasco Barreiros - [Damas Drive](https://appshunter.io/ios/app/damas-drive/id1451715393) - [GeoPT](https://appshunter.io/ios/app/geopt/id1517452091) - [GeoQuake](https://appshunter.io/ios/app/geoquake/id1529783642) - [PSKReporter Client](https://appshunter.io/ios/app/pskreporter-client/id6757393033) All apps by Vasco Barreiros: https://appshunter.io/developer/1451715392 ## Related topics [vasco barreiros](https://appshunter.io/ios/topics/vasco-barreiros) · [ham radio satellite tracker](https://appshunter.io/ios/topics/ham-radio-satellite-tracker) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
