With the information from Mashable website and Application Appannie, we can conclude that Apple’s Appstore is the most profitable market for commercial application, beside with highly revenue increment rate and many opportunities to grow Thailand become ideal market for application games. However with low information, it means low chance to succeed, so we should study the factors that effecting the buyer’s decisions.
With the result of the study from 400 samples found that the majority group of consumers are females age 16 - 24 years, with education level of bachelor's degree, being a student, with average monthly income of 10,000 or below, Play game around 15-30 minute per round, average buying game are below 1 game per month. The samples usually receive information about game from Apple Appstore and have friends to be influencer. The price which samples usually buy is around 1-2 U.S. dollar.

The suggestion of this study is the producer should design or segment game with sex of the player and don’t design game too long because player usually play a game around 15 – 30 minute per round.
