Any apps or websites that let you edit gifs?

I want to edit a couple of gifs. My goal is to put combine them one on top of another each with there own caption. I know it sounds confusing, but this is what I mean:
Caption 1
Gif 1
Caption 2
Gif 2
If that helps you understand better. Any websites or iphone apps that you know of that can do this please respond!

There are several good apps that let you edit gifs. They are,

1.Gifboom
Gifboom is one of the most popular GIF maker apps and houses a ton of great features. You can actually snap photos through the app or import ones already on your phone, use the front or back facing camera and apply filters similar to Instagram. Once your animated photo is ready, you can easily share it on social media. Gifboom is available both for iPhone and Android.

2. Cinemagram
Although similar to a GIF, a Cinemagram photo is actually a "stunning hybrid between photo and video." You can animate small sections of your photo, such as a hand waving or the pages of a book turning. While the rest of the photo stands still, only the portion of your choice is animated with movement. Cinmegram is currently available for iPhone only.

3. Gifture
This is another app that has a similar interface to Instagram. You'll find a nearly identical menu at the bottom along with an Instagram-like selection of photo filters. You can upload photos from your cameraroll and choose from customized playback rates for your animation. Instantly share your newly animated photo to your Gifture stream or to Twitter and Facebok. Gifture is available for iPhone only.

4. Loopcam
Loopcam has a great, easy to use interface that lets you create animated GIFs quickly, even when you're on the go. If you want lots of parts of your photo to move, Loopcam is probably a better alternative to something like Cinegram. View your GIF library in grid form and easily share them to social networking sites. Loocamp is available for iPhone only right now.
