Many of same problems plus user advice

If you have a hiss. Use headphones. The speakers and microphone are next to each other. You can highly improve quality this way. I had installed the latest update and it stopped working. I did get help after a day or so and the advice was backup the info via iTunes apps and then reinstall the app. That worked. It still crashes during undo scenarios and randomly during editing but still is a very useful tool. Incoming calls also crash your takes so use airplane mode if your serious about your time. Thanks for making this software. It has helped me tremendously with its on point convenience.
