A free program for Android, by ZAAX Consulting PLC.
Without multiple actions to perform just to trim a video, the Video Trimmer app lets you quickly cut a video and save it immediately on your device. It has a good interface so you can clearly identify where is the start and end points for trimming. This will not change the aspect ratio immediately as this will keep the size of the original one. One of the best features of this tool is that you may save your videos without any watermark.
It has an easy-to-use interface so anyone can maximize the use of this app.
