CamSextant vs Pressure Altimeter Tracker
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
CamSextant
This app functions as a celestial navigation tool, enabling users to take altitude measurements of celestial bodies using their phone. It provides real-time star and planet identification, automatic astronomical position calculations, and a perpetual nautical almanac.
- Celestial object altitude measurement
- Real-time star and planet identification
- Automatic astronomical position calculation
- Perpetual nautical almanac
- Audio star name and altitude announcement
- Horizon calibration

CamSextant is the easiest celestial navigation tool. It allows taking altitudes of celestial objects, using your phone as a sextant. It is a complete celestial navigation solution, with instrument, nautical almanac and celestial calculator. Point a celestial object and tap the image to capture the altitude and time. Stars and planets shown on screen in real time. Show constellation names and lines. Identify planets and navigation stars (from Hipparchus 150 catalog). The program can also speak the star names and altitudes (audio). Astronomic Position (AP) is automatically calculated once you have two sights. Calculate your astronomical position with less than 10 clicks. Perpetual nautical almanac using Astronomical Algorithms ( book by J. Meeus). If you take altitude observations of the same object, the average time/altitude are shown. You can calibrate the sextant horizon by reading the sea horizon altitude. Note that the phone is more like a bubble sextant: you don't need the sea horizon to use CamSextant. Anyway, click [Calibrate] button to save the correction. Calibration angle is subtracted from raw sensor reading. If you have a marine sextant at hand, you can edit the altitudes captured by the phone and get serious celestial navigation work done.

AltiTracker runs automatically in the background and keeps track of altitude changes in real time. The app's interactive graphs let you see and explore altitude changes and trends over time. With our Live Activities feature, AltiTracker shows your current altitude even when you phone is locked. You can select either sea-level operation or a relative altitude mode that tracks your altitude relative to a selected reference altitude (for example, your altitude relative to your base camp). Optional CSV export/import capabilities let you save your altitude data at ultra-high one-second resolution, and you can explore previously saved CSV altitude data directly in the app. The included Watch app can run stand-alone on your Watch fully independent of your iPhone. Our Watch app also let you easily adjust all key settings such as reference pressure or relative altitude. Real-time stats let you track your total climb/descent info, min/max altitude, vertical speed, and direction. You can set your sea level altitude or pressure manually, or use the GPS feature to obtain a reference altitude automatically. Our Live Background feature helps ensure that you maximize battery life by automatically turning off operation after the desired background runtime period. And our climb sensitivity feature helps minimize the classic problem of weather-based altimeter "drift" between active climbs. For mariners, our app can even estimate wave height and distance between waves. And for good measure, we included our NOAA/ICAO station-based weather data along with our amazing wind speed analyzer. As you can see, we set out to build the most advanced pressure-based altimeter app out there and we hope you give it a try!
