SloPro

iPhone App

With this application you can edit a video and run a specific part of it at low motion if recorded with this app. 

The section can be adjusted at very low fps (simulated by the software) and you can render the corresponding section of the slow motion effect. 

The edited file can be uploaded to Facebook and YouTube. 

Videon

iPhone App

This application is excellent for video editing and apply video filters and active zooming while recording. 

Rotate video, speed change, fps, flicker effect, compression, aspect ratio, etc.

You can trim, split, join, mute and add fix picture to videos and save them later to camera roll. 

I used it before uploading videos to YouTube. 

BannerFlo

iPhone app

With this banner application you can write your message and define the shape of each Pixel. 

The only problem of this application is the constant appearance of ads that sometimes becomes very annoying. 

Banner+ Free

App for iPhone 

With this application you can make a banner of your message with different options of color and speed plus the ability to make a banner of a picture. 

Ledit

This application for iPhone

With this application you can type a message and you will see it displayed with different colors and speed. 

I used this application to pick up a person at the airport instead of using the traditional paper sheet with the name of the passenger

I recommend it because there's no annoying ads appearing when you are working with the application.
