Awesome App

I finally could get ride of my huge amount of business cards that would always got lost when I needed them. Algo, the proximity feature worked really well in an event that I attended. Would recommend.

But when I use voice type on iOS,
Andrews become with extra spaces.
Bad. Bad. Bad
Can you trim spaces automatically, it's hard to remove them each time
