Google photos is a great way to organize and backup your photos on both your computer, Android & Apple devices
This service allows you to backup organize all of your photos via their cloud system. They offer unlimited backup as long as you are only uploading at their slightly compressed resolution instead of full resolution. The only thing required to get going with this is having a google account. If you would like to use Google Photos to upload full resolution you can purchase extra storage for that.
