PolarFinder Pro 对比 Air Quality Buddy 的使用情况和统计数据

This application allows you to make a precise stationing of the mount, excellent especially for astrophotographers and it works in both celestial poles. In the settings you can choose to exclude the GPS and enter the customized coordinates and / or even a particular date and time in order to know the exact position of the Polaris (northern hemisphere) or Sigma Octantis (southern hemisphere) for a certain place. This feature is also useful to know the peak of the polar for a specific place directly in the field without having to resort to third applications. Once the position has been calculated, the polar image will be shown exactly as it should be set in the polar telescope, remembering that it inverts the images (the app also allows real vision). ATTENTION: To use this app you need to see the Polar star and have a polar scope. Main features of the app: 1. Possibility to manually enter coordinates, date and time excluding the gps; 2. Various reticles available: - PolarFinder; - Skywatcher (old and new); - Ioptron; - Bresser; - Astro-Physics; - Takahashi; 3. Works in both hemispheres; 4. Possibility of activating/deactivating the view through the polar telescope (inverts the images); 5. Possibility of activating/deactivating the "Full Screen" view; 6. Possibility of activating/deactivating the "Super Dark" view; 7. Position of the Polaris or of the Octant very accurate thanks to the calculation of the phenomenon of the Precession; 8. Altimeter; 9. Very accurate help PLEASE NOTE: This app unlike most apps of its kind, takes into account the phenomenon of the Earth's Precession. The Earth has a rather complex movement, one of them is called the Precession where the rotational axis of Earths slowly changes its orientation and the celestial poles are slowly changing with it. This movement is rather small, around 26,000 years per revolution, but in time it changes the apparent position of celestial objects. As the right-ascension coordinate is used when calculating the hour angle, it is important to consider the effects of precession on the RA coordinate. For any problems, clarifications, suggestions or suggestions for improvement, write to me. I am at your complete disposal thanks and ... Clear Skies!

Air Quality Buddy

This is a Wear OS app that helps you stay on top of air pollution by providing location based air quality information. It works both as a standalone app, and also provides a complication that can be placed on your watch face. The air quality index is provided based on one of the standards that you can select within the app. Trial period & Subscription pricing: When you first start the application on a device, a 14-day trial period will begin. At the end of this trial period, a yearly subscription must be purchased in order to keep using the service. The price for the subscription is adjusted by country, and it will be presented to you at that point. It will be in the range of about 3 to 4 USD per year. Available indexes: - (EU) Common Air Quality Index (CAQI). - (US) Environmental Protection Agency (US-AQI). - (UK) Committee on the Medical Effects of Air Pollutants (UK-AQI). - (IN) National Air Quality Index (IN-AQI). - (CN) Ministry of Environmental Protection (CN-AQI). Permissions & Personal information: The stand alone app requires the fine location permissions to obtain air quality data in your area, while the complication requires the background location permission (so it can access the location while the application is closed). You will be asked for these permissions as they are needed. We also use a unique ID, to validate your trial license. More information on these topics can be found in the privacy policy. Feedback & Support: Please use the contact form if there are features you would like to see added or if you're having difficulties with the existing ones. I appreciate both positive and negative feedback, so don't hold back if you have any comments - I want to hear them all. Known problems: When the watch is connected to the phone, if the phone is in doze mode, it will stop serving location requests for the watch. This will result in the app taking longer to load new data, because it's waiting for a new location from the OS. The location request will fail, and it will fallback on the previous known location, then the request to our server will be made. This will result in fresh data, but for a potentially old location. I have no solution for this at this time, but as a work around, you can wake the phone up briefly when that happens, or just move it around. You can also simply ignore it because the last known location is likely correct, since doze mode only kicks in if the phone is stationary.
