This is a simple and effective app, perfect for trimming existing sounds. I had one ringtone that was too large to use and I only needed to trim it. I didn’t need the bells and whistles that other apps had, just a simple trim and this fit the bill perfectly. The Set Start/End buttons are handy and helpful to get a first trim and then fine tune it with the text boxes. I’d give it 5 stars if not for the start and end text boxes being a little difficult to modify times - you have to be careful what you type otherwise it might reset on you. Easy fix though.
