Polaroid and Poladroid
The release of the Fujifilm Instax Camera: 2009.
The Polaroid 300 Instant Camera: 2010.
(No difference in vignetting, just less overall dark tones and less contrasty than the heavy vignetting).
If memory serves, the older version also had the "fingerprint" option and a vintage tinting option which both are not in the newest version.
The application is free to download, so with no money invested it is fun to play with. However, we still think nothing beats a real Polaroid, not even the Poladroid.
