+ great website + great UX - knock just works if I touch my computer once (I would just type my password instead of knock my phone) - knock does not lock my computer if I knock to get a water or something at work for example (version 2 maybe?) - the download file could have the app name on it (I do not care about being a zip) - Expensive for this kind of feature (0.99 would be more appropriate) - Some information about how my password is being stored would be nice
