Curiosa is a tweak launched last evening that offers iDevice owners the option to be notified when an update is available for an application or a tweak from Cydia. Curiosa is currently available in beta version, so you can expect that it will not work 100% correctly after you install it. Curiosa has a dedicated menu in the Settings application of iOS and from there you can set the time period that passes between the checks made in Cydia, the gesture you can undertake to make a manual check and also the text of the notification displayed in iOS.
Curiosa was made to eliminate the need to open Cydia to check available updates for iDevices and notifications are displayed just like any other so we are talking about a very useful tweak. Curiosa can be installed for free from here http://rpetri.ch/repo/ but after the expiration of the beta version you will have to buy it.
