At first glance, Geo Bookmark looks like a rather pointless app. It adds a widget that lets you create geo bookmarks on the Home screen. You can then open the bookmarks using map apps like Google Maps or OsmAnd. But this one-trick pony can come in rather useful in many situations. On a trip, you can use Geo Bookmarks to save breadcrumbs for later reference. As a photographer, you can use the widget to track locations you've photographed.

The app is available on Google Play Store and F-Droid. Once you've installed it, add the Geo Bookmark widget to the Home screen, and you are done. Next time you need to bookmark the current location, tap on the widget, and it adds a bookmark to the Home screen. If the widget fails to get a GPS fix within 40 seconds, it creates a red bookmark for the last known location; otherwise it adds a blue bookmark. When you tap on the added bookmark, it opens in the map app of your choosing.
