Only 18 transactions allowed?!

Though the app works fine, when you get to your 19th transaction it says something like "You must upgrade to Deluxe! Only 18 entries are allowed on the free version!"

Why doesnt it say that anywhere? This bit of trickery doesnt entice me to buy the Deluxe version at all...
