Barometer Monitor

★★★★★ Barometer Monitor version 1.4, Sony Xperia Active, Android 4.04. Small storage and memory footprint. Small battery drain (compared to app "barograph"). Settings useful (time interval, time to keep data). Graphical display very good withpossibility to zoom. 4 stars only due to following limitations. Although it keeps recording data on the background even after application exit and screen shut off, at times it stops logging the data. I have not figured out yet what are the specific circumstances implying the logging interruption. The CSV export works well, but the output file requires some work before it can be of use due to the date format (US "Month in letters Day, year H:MM:SS AM/PM" in my case) and to the mixture of commas and spaces to separate the fields. It could be better to have coma separated separate fields for year, month (as a number), day, hour (24h format), minutes, seconds, pressure to make the rearrangement of the CSV data file fields easier for anybody. It could imply to have intermediary steps in the application code to convert the date and time format extracted from the system to the format that I propose. Despite these flaws, this is my favorite barometer app.

★★★★★ Simple & effective You can a have a barometric pressure running record presented as a graph or a table. It would be nice if the timescale shown on the graph really represented the selected timescale. It would be even nicer to be able to calibrate off known local elevations. But I use the app every day on my boat. Thanks. Nexus 5, 6.0.1

★★★★★ good and simple it will be useful to see a larger period of time (not only a week) and also to see the date (not only the time) on the chart.

★★☆☆☆ Excellent but caused phone sensors to fail Excellent app and pretty accurate. Unfortunately it causes the phone sensors to fail, initially the phone is fine then after a random amount of time it will stop autorotating, curable with a reboot. Most inconvenient!

★★☆☆☆ Graphical display needs work Seems to work ok, but the bizarre annotation of the x-axis makes it pretty much useless. No dates, just seemingly random times of day stretching back a week. Also, it really could do with longer than a week as a maximum display period.

★★☆☆☆ Graph not visible The data listing is functioning fine but there is no visible plot line displayed on the graph despite a lengthy data file. Google Nexus 4.
