[Update] Lookback (0.5.1)

* Password fields and the keyboard are now hidden when inputting a password
* Fixes the ugly blue pixel on the record button ;)
* Lookback is now much better at finding the icon of your app and uploading it to the web site
* Non-retina resolution video is now captured from iPads, even if they have a retina display.
