QR Thing vs ShortShot

This application lets you scan and create QR codes, without spying on you or showing you ads. When creating QR Codes, multiple design aspects can be changed like pixel shape, thickness/scale and foreground and background colors. You can also add a custom logo to your QR code. The QR code can then be exported/shared as PNG or SVG without additional cost, registration or anything else being required unexpectedly. It's the perfect app if (and I wrote it because) other apps disappoint with lock-in, spying, ads or outright scams (like pretending to create a code containing your URL, but it points to their domain so they can extort you later on).

ShortShot is built for photos that are useful right now and meaningless later. Instead of filling your photo library with one-off pictures of locker numbers, parking locations, hotel room doors, or temporary notes, ShortShot keeps those photos separate and easy to reach. Open the app, take the picture, and it stays available exactly for as long as you need it. When you come back soon after, or return to the same place, ShortShot can immediately surface the most relevant active photo again so it is ready when you need it. When you are done, delete it with one tap. If you prefer, ShortShot can also remove expired reminder photos automatically.
