Hi Disha, I would like to recommend you 'Video Stamper: Add Text and Timestamp to videos' Android application.
Hi,according your demand for a video editing software, i recommend you the TunesKit Acemovi which is simple and easy to use, it's friendly to user. It not only can add text,cut,crop video, but provide lots of effects for user to make fantastic and interesting video.So maybe you can have a try.
