Leading this week’s must-have apps roundup is a terrific photography app called StillShot, which allows you to extract full-resolution still images from your videos. It breaks your clips down into frames and allows you to save the best ones — all for less than a dollar.
We’ve also got a great note-taking app that claims to be the “word-processor for visual thinking,” an app that will ensure you never forget your grocery shopping list again, plus terrific updates to Flipboard and The Weather Channel.
