Im not sure where the rest of these reviews came from but this app is boring and doesnt get the job done compared to others. First off, please know I got it from a Starbucks download option. Even though the arrows are easy to add you cant add any width or color to them which makes it one dimensional. Also if you tap in too many places it adds new arrows and they are not easy to remove. I think this app developer has paid for the high reviews to be posted because I dont understand its simplicity in a market that is already populated with better options.
