Excellent

This is a general purpose app for GIF users. You can import photos, Live Photos, videos, gifs, trim the length, add color filters, adjust brightness and contrast, add and resize the texts with many fonts, adjust the play speed, add a little cool signs, and save and/or share them in GIF or MP4 formats.
The best feature is there is no watermark.
The missing feature is it would not support WeChat. Otherwise I will give it a five star rating.
