AimSat vs TachoCamera

Point your phone - or your antenna - at any satellite in real time. AimSat gives you live azimuth and elevation for over 50 satellites: the International Space Station, MUOS military UHF birds, WGS broadband relays, amateur AMSAT passes, weather satellites, and more. WHAT IT DOES - Live sky position (azimuth + elevation) updated every second from your GPS - SGP4/SDP4 orbital propagation - the same math NASA uses, running on-device - Antenna alignment mode: hold your phone like a tray, tilt it up, and the crosshair tells you exactly where to point - Pass notifications: get alerted before a satellite rises over your horizon - Garmin watch support: az/el values mirror to your wrist hands-free - Filter by category: ISS, Amateur, Weather, GEO, MUOS, WGS - Pin, hide, and sort satellites to match your workflow - Full ground-track map with sub-satellite point AIMSAT PRO Upgrade once ($2.99) and unlock the 7-day pass planner - see every satellite window for the full week ahead, export passes to your calendar, and plan before you're in the field. No subscription, ever. BUILT FOR OPERATORS Whether you're a ham radio operator chasing FM satellites, a SATCOM technician aligning a terminal, or just someone who wants to wave at the ISS - AimSat has the precision you need without the bloat you don't. PRIVACY Your location never leaves your device. No accounts, no analytics, no tracking. Orbital data is fetched from CelesTrak and Space-Track; everything else runs offline.

TachoCamera turns your iPhone into a professional stroboscopic tachometer — no additional hardware required. Point the camera at any rotating or moving object, tune the frequency, and when the motion appears frozen — you've found the speed. Works equally well for rotating parts (motors, fans, turbines, pulleys) and for linear or repetitive motion (conveyor belts, production lines, packaging, printing). KEY FEATURES • Stroboscopic measurement — freeze rotating or moving motion with the camera flash to measure speed with precision • Auto RPM detection — let the app automatically detect rotation speed using the camera • Linear scan detector — measure the speed of objects passing through a detection line, ideal for conveyors and production lines • Machine library — save and organize your machines and components with QR codes for instant access • QR code scanner — scan machine QR codes to load saved settings instantly • Snapshot on save — automatically captures a photo when saving a measurement DESIGNED FOR PROFESSIONALS TachoCamera is built for maintenance engineers, technicians, and production/quality staff who need reliable speed measurement in the field — whether it's a rotating motor or a fast-moving product on a line. PRO SUBSCRIPTION Try Pro free for 3 days — after the trial, a subscription unlocks the app's full features. • Monthly plan: $7.99/month • Annual plan: $59.99/year Subscriptions are billed through your Apple ID account.
