Navigate to locations entered in 10-figure Great Britain Ordnance Survey (OS Grid format), directly from your watch. With OS Grid Locations you can quickly add multiple locations without a GPS fix (*) and navigate to them using native apps, such as running, cycling or hiking.
Supported watches: FR645, FR645M, FR935, Fenix 5 (all variants), Fenix Chronos, D2 Delta (all variants).
The app can be downloaded here:

As a Widget, this app has the added convenience of being quickly accessible from the watchface. With this app, you can start adding a location in as quickly as 3 button presses, without a GPS fix:
Up/Down (scroll to widget), Start (launch widget), Start (select Add).
In contrast, the normal method requires a GPS fix (on some watches), and takes a few more button presses.
You can also access the list of saved locations (created by this app) much more quickly than the normal method..
(*) Some devices, such as 645/645M, are unable to add locations without a GPS fix, as they lack the "Navigate to Coordinates" feature found in other watches such as 935 and Fenix.
However, even the "Navigate to Coordinates" feature is only practical for adding one location (named "Coordinates") which will be replaced the next time you use that feature. It would be technically possible to add multiple locations in a one sitting by renaming the Coordinates location after each time, but that would be a lot of button presses and it doesn't seem practical to me.
So even on the watches with advanced navigation, this app is probably the quickest/most practical way to add multiple locations from coordinates, directly on the watch.
