You can use a gps logging app (I use gps logger on android) to create gps tracks and sync them with your photos via the timestamp. Digikam has a tool for that built in, not sure what other software supports it.
This way I don’t have to manually tag every photo but instead only those where the gps failed because I was underground or where I forgot to turn it on





I usually tell me that I’ll be happy to have already done that thing later in the day whereas I will curse my earlier self if I still haven’t done it.
Sometimes it even works. Usually for small stuff like emptying the dish washer at least.
