This Duck Quacking app makes your phone quack like a duck.
Switch between three modes:
Push button to quack! Guaranteed hours of fun.
Quack at random intervals, N quacks per minute on average. Randomness between quacks is determined by a Poisson distribution.
Flock of ducks croaking continuously on a loop. (This is the app's best feature.)
Additionally, user may select to read fascinating, fun facts about ducks. For every random fact, there's a 1 in 4 chance of showing an Interstitial ad (sorry, gotta pay those bills).
Remember - if it looks like a duck, and it quacks like a duck, it's your mobile phone**
