Eos Tools Pro is a monitoring utility for the Arrow and Skadi series high precision GNSS receivers from Eos Positioning Systems. It provides advanced GNSS information such as RMS values, PDOP, differential status, satellites tracked and used, that are critical for submeter and centimeter GIS and surveying data collection. The app features a built-in end trip client to access RTK or DGNSS corrections from an RTK network. Eos Tools Pro also allows audible user configurable alarms and runs in the background of your mapping surveying software. Features: - Built-in NTRIP client to connect to an RTK Network - Displays GNSS and Tilt Compensation accuracy with quality control information - Select the Skadi Smart Handle mode: Extensible Virtual Range Pole™ or Invisible Range Pole™ - Satellite view for all constellations in use (GPS, GLONASS, BeiDou, QZSS and IRNSS) - User configurable alarms - Orthometric Height (Geoid models for vertical datum) - Compute and apply Position Shifts to accommodate different - Laser Offset Mapping for Esri ArcGIS® Field Maps - Locate and map underground utility assets directly in ArcGIS Field Maps - Terminal emulator to send configuration commands to the receiver - HTML5 built-in browser Disclaimer: "Continued use of Eos Tools Pro running in the background and connected to the GPS/GNSS receiver can dramatically decrease the battery life of your Apple device."

GPS Test Satellite Tracker combines a live satellite radar with a real GPS/GNSS status screen. RADAR Track Starlink, the ISS, navigation satellites, communication satellites and other orbital objects on a compass radar, positioned relative to your location. Satellite positions are predicted from public orbital data (TLE) using the SGP4 model. GPS / GNSS STATUS See your device's real GPS fix from iOS — position, altitude, speed and location accuracy. Alongside it, view the navigation satellites (GPS, Galileo, GLONASS, BeiDou, QZSS, SBAS and NavIC) calculated to be above your horizon, split into "in use" and "in view," with signal estimated from elevation. Because iOS does not expose the receiver's raw satellite list, the satellite view is computed from orbit data — while your position and accuracy are the device's real values. FEATURES - Live satellite radar for Starlink, ISS and orbital objects - Real GPS fix quality, accuracy and location data - GNSS satellites overhead: in use vs in view - Full orbit track and telemetry for any satellite - Signal indicators, NORAD IDs, footprint, altitude and more Terms of Use (EULA): https://developer-barseghyan.github.io/satellite-tracker-support/terms Privacy Policy: https://developer-barseghyan.github.io/satellite-tracker-support/privacy

Verdict
The clearest difference is rating: Eos Tools Pro at 4.6 against GPS Test Satellite Tracker's 3.5. Eos Tools Pro also leads on in-app purchases (none vs 2) and ratings volume (9 vs 2). GPS Test Satellite Tracker's advantage is review sentiment (50% vs 38%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. GPS Test Satellite Tracker sells 2 in-app purchases, starting at $9.99 per month. Eos Tools Pro asks for nothing beyond the download.
Eos Tools Pro holds the better App Store score, 4.6 against 3.5. Both are backed by a comparable volume of ratings — 9 and 2 respectively. Written reviews complicate that: 38% of Eos Tools Pro's written reviews are positive against 50% of GPS Test Satellite Tracker's, so the app with the better star average is not the one people write more warmly about.
