Response from developer
May I please note that the listed functions of the free Marine Barometer are not in any way tied to the functions of the Marine Barograph app. The latter is a totally separate app with enhanced storage and display options, but none of these are needed to benefit from the described functions of the Marine Barometer.
Great app!
Marine Barometer
Good tool
Could really gain from having some sort of graphing tool to easily see the trends.
Useful but could be better
Excellent
Thank you!
Best in the App Store
My wife and I are offshore sailors, and I’ve been looking for a really accurate barometer for about a year. I really accurate barometers are really expensive, so I hoped to make do with an iPhone app.
I think I have most of them, at this point, but this is the first one that ticks all the most important boxes.
First, it’s not a black box with hard to understand calibration parameters. It has exactly two, and they are the two obvious and critical ones: altitude and sensor offset. These are the only two required for accurate readings, so I’m not sure why other apps have more. This is a case where more is not better.
Second, it averages the readings. The sensor in the iPhone is pretty jittery so averaging is absolutely necessary.
The result is a simple, accurate barometer that — I hope — will stay accurate over a goodly period of time. I haven’t used it long enough to know if it drifts over time, but I guess that would be the fault of the sensor, not the app.
I intend to track its accuracy over time, with the hope I don’t have to buy one of those $700 barometers!
Well done.
