    The app with the radiation-watch.org dongle works well, however I do have a short wish list: 1) could work with longer than 10 minute count times. 2) would be nice if a .csv file could be created from the count graph for Excel or Open Office spreadsheets. 3) clicking with each count or even an alarm for count rates that the user could preset. The photo diode dongle works well, however is not

    Nothing special from what I can see, and when you consider the admission of the nsa spying on cell phones. Call me crazy, but last thing I need is another tool that can be easily hacked considering you have to give full permissions to the Mic for this to work. That's just me.

    works good but only on phones because tablets it does not go into landscape at this point also no updates?? for a long time like to see back ground color change so not only a sound but also a visual warning... would be great
