Yukon

The application, interfacing with the devices of the Geca Yukon series, allows you to monitor in real time the quality of the air present in the home and check critical situations. Thanks to the WiFi connection, all Yukon devices are able to communicate to the user's smartphone any changes in air quality status or a gas leak. It is possible to keep under control the parameters detected in the environment and the overcoming of the thresholds dangerous to health (established by WHO) or to safety of the person. The Yukon App allows you to monitor the progress of measurements over the time and from the user profile you can manage the settings of notifications, passwords and individual sensors. It also allows the creation of groups of sensors (Rooms), in order to divide different detection areas. All Yukon products and more info are available on the website: www.yukon-air-quality.com

Verdict
The clearest difference is in-app purchases: Yukon at none against StackDays App's 3. Yukon also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.3). StackDays App's advantage is update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.
