Thank you. This really should be on the website somewhere too. The only reason I downloaded your app at all was that your last blog post mentioned that you don't collect data. I'm usually very cautious about things that involve messing with my email, contacts or calendars.

Also, I didn't watch the video so felt as though I was forced to go hunting for more info on the site. You say you A/B tested but did you also test a version with video and text on the front page? I'd be surprised if video alone performed better.

Edit: Now watched the video (having dug out my headphones so I don't disturb co-workers). It actually does do a good job of describing the problem and how the product works. Looking forward to trying this out.

I'll be recommending it as much as possible now that it is easily accessible in the App Store.
