BalloonMaker is described as follows:
Up, Up, and Away...BalloonMaker has a rating of 4.6 stars in Google Play and 3.1 stars in the Amazon Appstore.
Balloon physics is perfected in BalloonMaker, a simple yet entertaining app in which you inflate and pop vibrantly-colored balloons. The realistic balloon-like motions and sounds are fun for all ages.
Watching All the Red (and Yellow and Pink and Green) Balloons Go By
Watch your balloons inflate as you press your fingers to the screen. When they reach the size you like, let go and watch them float up. While your balloons are inflating, drag them around the screen and watch them bump other balloons out of their way. Tilt your device in any direction and watch your balloons rotate and float against gravity. Your balloons also bounce off of the sides of your screen and ricochet gently off one another.
Shake your device to switch from day to night, and night to day. Touch your balloons to pop them after you let them go--the bigger the balloon, the bigger the pop. The bigger the pop, the more it affects the flight of your other balloons. Your balloons can't be popped right away after you release them, so you can make a steady stream of balloons fly from your fingers as you quickly tap at the screen. You can pop them when they are about a half-second old. Use several fingers to create multiple balloons at once, pop multiple balloons at once, drag them around all together, or pop one and create one at the same time.
Little kids will love to occupy themselves playing with BalloonMaker. Older kids and adults will also enjoy relaxing with the endless balloons that they create and pop. The multi-touch tracking and reliability of performance in this app make it great for children with autism. The simplicity, consistency, predictability, and relaxation factor of this app has proven very enjoyable for autistic children.
"Balloon Maker by TegTap is adaptable to several classroom uses; it is a multi-user app that gives instant feedback when blowing and working with the balloons." - Out-of-School Time, TutoringGreatKids.org

what it means to developers.
Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
