The chart below shows the number of apps that were sold in three different stores from 2010 to 2014.

The bar chart illustrates how many mobile applications were purchased in the

iOS

App

Store

,

Google

Play and Amazon Appstore between 2010 and 2014.

Overall

, the most striking feature is that the total

number

of

apps

increased considerably in every

store

over the period,

however

,

while

in 2010 the

iOS

App

Store

was the most popular one, it was overtaken by

Google

Play in 2014.

In contrast

, Amazon Appstore remained the least popular, despite a significant rise over time. In 2010, the

iOS

App

Store

dominated the market, with just over 150,000

apps

being purchased,

whereas

the

number

of

apps

bought in

Google

Play was well below 50,000.

However

, even with the

iOS

App

Store

growing steadily every year and amounting to roughly 250,000 in 2011 and 450,000 in 2012,

Google

Play saw a much more dramatic increase, doubling in 2011 and tripling in 2012, which amounted to just over 300,000

apps

sold.

Furthermore

, the

number

of

apps

purchased in the

iOS

App

Store

, which stood at approximately 750,000 in 2013 and was just slightly over the

number

of

apps

sold in

Google

Play, had soared to 1,200,000 by 2014, with

Google

Play overtaking it and amounting to 1,350,000 the same year. Amazon Appstore, which stood at roughly 0 in 2010, had the least

number

of

apps

sold over time.

Nonetheless

, each year it rose steadily and had amounted to just under 300,000 by 2014, which was the same level as the

iOS

App

Store

in 2011 and

Google

Play in 2012.
