Limited unit and plot control

I bought this app to download and view temperature and pressure data from my D3 Drop.

The app works very well when downloading the data from the logger, but the app offers limited control over display units (imperial or metric) and more importantly, pressure and time scales. The pressure plot always shows as a horizontal line, regardless of daily pressure variations, because the display scale is fixed at 29 to 32 inHg. This range scale is fine when a hurricane passes through, but useless for daily/weekly variations. Of course I can (and have) export the data to my phone or laptop, then plot using database software, but this defeats the reason to have the app plot the data.

So two stars overall - good for downloading data from the logger, but useless for plotting that data.

No no no no no!!!!!! ,

Great Idea

This app is an awesome idea. In theory, I can set the kestrel on a stand and not have to run up to it every time I want a reading. However, the app needs to be updated to be able to select individual units of measure like the kestrel can. I’m an Air Force weather tech and we take readings in knots. The current app only allows for imperial or metric which reads out as either MPH or m/s. Being able to individually select each unit of measure on the app would help out greatly! Please update!

Completely Unusable on Xs Max

A number of the controls are directly underneath the new “home button” at the bottom of the screen, so when trying to use them, the app is closed — which means disconnection from the Kestrel device, and having to start what you were trying to do from the beginning.

Everything is also sized incorrectly (“squished” from the right side in, as if it were stretched from intended use on a smaller screen).

Export functions also do... nothing; Not even error message.
