Merlin24Legacy
· v1.0.3
About
The Merlin24Legacy watch face provides a simple layout with customizable features including temperature, heart rate, steps, and other data.
When temperature is displayed, a separate date format is used so the date does not overlap with temperature.
A secondary clock can also be displayed with a custom time zone based on UTC offset.
--------------------
NOTE: Temperature is not compatible with D2 Bravo; fenix 3; Forerunner 45, 230, 235, 630; and Garmin Swim 2.

FAQ for temperature:
Q: Which option should I use?
A: Garmin Weather is best. OpenWeatherMap gets data from a website. The internal sensor may be affected by your body heat (some devices can use Garmin tempe).
Q: Why "--"?
A: No temperature data. When OpenWeatherMap is first enabled, you may see "--" for up to 5 minutes before temperature is displayed. Otherwise restart device, reinstall app, or wait for new data. Data availability varies by location. If problem persists for GarminWeather, contact Garmin Customer Support.
Q: Why "GPS"?
A: No GPS data. Open an activity that uses GPS. Then close the activity and wait up to 5 minutes.
Q: Why "API"?
A: Merlin24 uses a default API key for OpenWeatherMap. If lots of people use it the limit will be exceeded. You can get your own API key for free at openweathermap.org, then paste it in the settings for Merlin24. If you still see this error, the API key has a typo or is invalid.
Q: Why "BLE"?
A: Problem with Bluetooth. Reconnect Bluetooth.
Q: Why is temperature inaccurate?
A: (1) Update the GPS by opening an activity; see above. (2) Reconnect Bluetooth or restart device or wait for new data. In the settings you can set a time limit to show "--" so you will not be confused with an incorrect value.

The app name was inspired by the merlin falcon.
The original app layout was modeled after the CleanSteps watch face by jonasbc.
