Download of Netmo 1.9.15 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Lifestyle Tools, more precisely Weather. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. This Mac application was originally developed by Andreas Grossauer.
From the developer:
Netmo is a menu bar app for viewing the weather data from the Netatmo Weather Stations. In addition to the current data, Netmo displays the course of temperature, air pressure, humidity, CO2, rainfall, and the wind speed over definable time periods in nice and clear charts.
You may want to check out more Mac applications, such as Outside - Weather Reports and Forecasts, multiWeather or Global Warmth, which might be similar to Netmo.
