Tag Photo - clean storage

This is an useful tool to enhance the Photos App:
1) Give your photos/videos a text memo, also a color tag. With this app, you can easily find out your photo or video.
2) Cleanup the storage of your iPhone/iPad. Sort videos and photos by their size to let you know which one can be deleted first to save storage space.
When enjoying photos/videos, you can note them or tag them with color.
For example:
1) When you classify photos of your kid, you can note them as "baby 1 year 1 month". So, you can input "1 year", or "1 year 1 month", or "baby 1 year", and so on, to get all photos when your baby is 1 year old.
2) When watching photos, you can give all photos related to your travel a "blue" tag. Then, you can select "blue" tag to get photos about your travel.
