Miss my baby girl

I had to move 800 miles and couldn't take my puppy with me. She just turned 6 last month and I miss her so so much. My parents are taking care of her until I afford to get her trained to not bark at everything. Then I'll get into a place that accepts animals and go get her. I want to make a slideshow of my favorite pictures of her/us. I have an LG so there's not much I can do on it. What are some good apps for editing photos and putting together slideshows? My phone can already edit and make slideshows/collages, but I feel like an app has more options. I also have no idea how to edit a photo so it looks nice so I guess we'll be doing a trial and error
