Nice, but really just a preview of paid version
This free version will give prospective buyer an idea of how the clock looks, but the beautifully presented works of art are marred by the intrusive, incompatible, often ugly ads. I have no quarrel with ads in free apps. A developer has a right to be compensated for his work. However, sometimes the ads detract so much from the app that it ceases to retain its value. That is the case here. Download the free app to see how it might look, but be prepared to buy the paid version if you want to enjoy the art masterpieces provided.
