Very detailed weather app

Love all the information presented at a glance. Hope to see even more customization and weather information in the future, such as summaries/descriptions for each day in the forecast, like other weather apps.
Bug: In Comparison shows °C difference even though °F set in the settings. Update: Bug fixed, thanks

Response from developer

Thank you for the helpful report, and sorry for the confusion! You’re right: the temperature difference in the comparison card was always calculated and shown in °C, even with °F selected in the settings. This is fixed and will be included in the next update. Thanks for taking the time to tell us. If you notice anything else that doesn’t match your settings, please let us know!
