3rd party google photos app ?

hi there

i am looking for a home for my 15k+ photo library, was using revel but i am migrating now since i diiscovered its not fault tolerant

any way, i love google photos feature set

the problem is none of my family members use google+, nor they are intersted in

so are there any dedicated google photos aps ? for example right now i can only filter photos by " i am included in"

can i do the same but with a diffrent person tagged ?

regards

ahmed
