Answer 1

1)In App Purchase:
An app that utilizes in-app purchases offers a free version of the app that includes additional, optional, paid features. These are commonly seen in gaming apps where users are encouraged to purchase new levels, gear, and items. These types of purchases encourage repeat purchases because they are consumable, such as buying extra lives in Candy Crush Saga. In-app purchases are also found also outside the mobile gaming world in apps like Calcbot, 1Password, or even Apple Music. This second category of in-app purchases lets you continue to use what you purchase unlike consumable items that don't remain once they're used, such as extra lives in Candy Crush Saga. Free apps that have a paid component to provide access to an additional feature or set of features are referred to as “freemium.".

2)In App Advertising:
In-app advertising comes in a variety of sizes, positions and placements in mobile apps. The amount of revenue you generate from in-app advertising is based off of traditional advertising models. Advertising can pay differently for click-throughs, impressions,which countries the users are from, and the format of the ads, with videos tending to be worth more than static ads.
