Decoder format is not what’s advertised.

If you’re looking for a decoder that is in the same format as the preview then DON’T buy this app.

Response from developer

Apologies for your bad experience with our app. The shown SNOWTAM format is the old/previous regulation and is not used anymore. Our Application has changed to the new Global Reporting Format. We will check, why the old screenshots are still showing and correct them. The App-Details however state the correct Format (SNOWTAM GRF).

Useless

The holdover times are fluid specific. Therefore without the ability to specify the type of fluid by name, the times are completely meaningless and potentially very dangerous. Do NOT use this app. Look the data up in the published holdover times for the specific fluid used.
Deleted the app as dangerous. Shame I can't get my money back.
