This app seems to keep getting more expensive, but when going through it today I noticed a 50% off promotion for the lifetime premium upgrade via in-app purchase.
There's nothing saying that it is targeted, but the 'unlocker' app available at https://play.google.com/store/apps/details?id=com.urbandroid... is still full price, so it might be targeted. Best to just open the app and have a look for yourself.
