A free app for Android, by Platfarm Inc..
NEON GIFTEXT Video Effects is an amazing collection of over 1,000,000 neon GIFs, backgrounds, icons, symbols, and fonts. The collection is so large that you can easily find what you need. The best part is that the collection is free to use, so you don't have to worry about paying for it.
The main screen of the app is a list of all the available effects. Each effect has its own settings, and you can change the settings to make the effect work better on your video.
The main thing is that you can use the collection to create your own video and upload it to your social media accounts.
