I got this app mainly because I wanted a simple voice memo app on my Apple Watch. This app certainly delivers that. However, I also found that I love the iPhone app. I hadnt realized how annoying it was to have to keep hitting buttons on the standard memo app - open app, start recording, stop recording, save, etc. The iPhone app makes it easy to quickly make a note and not do extra stuff.
There isnt a complication for the Apple Watch yet, but Ive found that I just keep the Say&Go glance as the current glance, and that works fine. I just swipe up to get the glance, tap twice to start recording (with a slight pause between taps), and Im recording a note with barely looking at the screen.
