To create a successful app strategy for Latin America, follow these steps:
Cost Per Install (CPI) varies by country, with Brazil and Mexico being the most expensive. Other countries, such as Colombia, have lower market value and a lower CPI.
A majority of LATAM mobile phone owners are on prepaid plans and often lack credit cards or bank accounts. Make sure you fully understand the money challenges of your target market before diving in.
Partner with them to learn about the target market's cultures and beliefs. That knowledge will help you to market your app successfully.
If you can find a smaller, regional app store, you will have a much better chance at people seeing and downloading your app. While it's easy to publish an app on Google Play, your app is published in an ocean of other apps, which can make it very difficult for users to find.
These laws may be national, regional, and local in scope. You may not need to be a lawyer, but you may want to make friends with one that lives in your target market.
