SRTool has simple yet powerful features, helping you to be more productive and focus on the things that really matter.
This is a lightweight and easy-to-use subtitle editor for srt files. Create subtitles from scratch or import your existing ones, set colors and font attributes, or select the position of each frame. The built-in video view and the timeline will support you to create frames with accurate timings. Once you are done, you can also export your video with hard subtitle - this function is offered as In-App Purchase.
