As the fourth most populous country in the world, third country that drives the most downloads on the Play Store, and the third largest digital economy by 2025 – Indonesia is booming. Localizing your apps and games for Indonesia, therefore, becomes an increasing priority. We’ve gathered for you all the information and tips you need to know to localize your app/game in the Indonesian app market successfully.

Mobile landscape in Indonesia

iOS vs Android

Android dominates the Indonesian market with almost 90% market share (October 2022). Low to mid-range smartphones (under US$250) produced by East Asian brands such as OPPO, vivo, and Samsung have the lion’s share of the market and run on Android. On the other hand, iPhones are more expensive and harder to get because there is no App Store in Indonesia. So, iOS has to make do with the last 10% of the market share.

Android should, therefore, be your priority market if you want to localize your app in Indonesia. This analysis will focus on Google Play as well.

Top apps in Indonesia

Both local and non-local developers are present in the top 10 charts of the Google Play Store in Indonesia. However, the non-local developers often predominate.

Multiple local developers, nonetheless, manage to rank in the top 3 of these charts. Alarge part of the non-local developers that rank in the top 10 charts have their headquarters based in East or Southeast Asia. Western apps also manage to penetrate the Indonesian market with popular apps, such as Tinder, Messenger, Pinterest, and Amazon Prime Video, making it into the top 10 in their respective categories.

In terms of app preferences, Indonesians lean more toward Tools, Video Players, Social, and Entertainment apps. These categories drive the most downloads and the highest in-app revenue. Apps that belong to these categories make up more than half of the top 10 free apps in Indonesia.

Mobile gaming landscape in Indonesia

With a total of 1.47 billion downloads and a revenue of $142 million in 2021, Indonesia is one of the biggest mobile game markets worldwide. Non-local developers dominate the top 10 free and grossing games charts. Some of the most popular mobile games in Indonesia are Western and Asian games, such as Mobile Legends (Moonton, China), Garena Free Fire (Garena International, Singapore), FIFA Mobile (Electronic Arts, USA), Clash of Clans (Supercell, Finland), and Subway Surfers (SYBO Games, Denmark). Most non-local game developers do not make any localization efforts other than translating their app page metadata.

Game categories that drive the most downloads in Indonesia generally do not drive a high in-app revenue. Among the game categories that drive the most downloads, Simulation, Casual, Educational, and Arcade games are some of the best performing ones. Role-playing and Strategy games, on the other hand, drive less downloads but generate a higher in-app revenue.

Action games are by far the favorite of Indonesians. These games generate the most downloads and the highest in-app revenue. They also occupy a quarter of the top 10 free and grossing charts.

Indonesia is a very diverse country, both in terms of language and culture. With over 700 living languages, Indonesia is the second most linguistically diverse country and accounts for 10% of the world’s languages.

At the national level though, Indonesian is the only language recognized by the government. Indonesian is used as a “lingua franca,” that is a language used for communication between groups of people who speak different languages. It is only at the regional level that Indonesian indigenous languages are recognized. Among these indigenous languages, the most spoken are Javanese (spoken by over 30% of the population), Sundanese, and Malay.

  • On Google Play, Indonesian is the predominant language. Like English, the Indonesian language uses a Roman alphabet of 26 letters that has no particular accentuation and is pronounced the same way it is written.
  • As a general rule, Indonesian is between 8% and 12% longer to write than English, which is something to consider when optimizing your app metadata.

We strongly recommended working with a professional translator, who is a native speaker, to translate your metadata to Indonesian. They will be able to help you match the cultural and linguistic specifics of Indonesia and increase your chances of success in localizing your app.

1. Title

In Indonesia, most of the foreign apps and games keep their original brand name. Only some of them make the extra step of translating their brand name into Indonesian as well, like which becomes, but this is far from necessary. Many apps and games, however, add generic descriptive keywords as an extension to the title. These descriptive keywords are sometimes in Indonesian and sometimes in English. Titles that include English keywords are generally well received in Indonesia.

Though uncommon, brand names are sometimes translated into Indonesian. However, descriptive keywords are often added after the brand name, either in English or Indonesian.

2. Short description

  • The vast majority of app short descriptions are written in Indonesian. Only a few apps provide Google with a short description that is written in English.

For instance, Vidio, one of the top streaming apps in Indonesia, have their short description written in English as the vocabulary related to streaming services is often taken from English. However, these are exceptions.

Examples of English words that have high search volumes in Indonesia
Targeting universally used English words in your app metadata in Indonesia can sometimes improve your app’s visibility on the Play Store, as did Vidio.

Some English words have entered the everyday language in Indonesia, especially among young people. This should be taken into account when localizing your metadata in Indonesia. Checking the difference in keyword search volumes between the Indonesian version and the English version will let you know which keyword can give your app the highest visibility.

Expert Tip

If you don’t provide Google with a short description, it will automatically translate the one you have in your default locale. This can be problematic as Google’s auto-translate can include errors, and it is also a missed opportunity for your app to target relevant keywords that can boost your visibility. We, therefore, recommend always providing a short description written in Indonesian.

3. Long description

Long descriptions are very often written in Indonesian.

  • They are also well-structured – paragraphs, bulleted lists, and subheadings – to make long descriptions more easily readable.
  • Multiple apps also use colors to highlight the most important information.

  • Like titles, long descriptions often include a few English words. This is common in Indonesia. Except for the subtitles, many app page elements include a mix of Vietnamese and English words. The latter are thus found not only in the titles and long descriptions of app pages but also in the captions of their screenshots.


Localizing app creatives is a common practice in Indonesia. Many foreign apps adapt the content displayed in their screenshots to be more relevant for the local audience.

For example, Spotify displays Indonesian-focused podcasts, music, and playlists in its UI.

  • As a rule of thumb, Indonesians prefer portrait orientation screenshots.
  • Screenshots also often feature colorful backgrounds. Neon colors with gradients in particular are popular in Indonesia, with regular usage of electric blue, bright red, magenta, and bright purple.

Here are some best practices to localize your Indonesian app creatives successfully:

1. Add both Indonesian and English words in screenshot captions

Indonesians understand universally used English words, so it’s not unusual to use a mix of Indonesian and English on app pages, including in the screenshots’ captions.

For example, let’s look at the Asian entertainment app WeTV and the e-commerce app Tokopedia. The former uses English in some of its main captions and Indonesian in its sub-captions. As for Tokopedia, it uses English as well as Indonesian phrases in its screenshots; they’re highlighted in the UI as well.

English words are not only used in the screenshots’ captions but are also displayed within the in-app screenshots in Indonesia

2. Show social proofs & promotions in your app creatives

Indonesian store visitors are positively influenced by social proofing and promotions. Therefore, many apps capitalize on this and include social proofs and promotions in their first few screenshot cards and feature graphics to give them the most exposure.

Keep in mind though that Google Play does not favor this practice.

3. Highlight cultural diversity in your app creatives

Indonesia is a very diverse country not only in terms of languages but also cultures. Many apps acknowledge this and highlight Indonesia’s cultural diversity in their screenshots, thus appealing to a larger pool of store visitors.

For example, Mango Live and Hago use models of different age, religion, and ethnicity in their screenshots.

4. Screenshots featuring Muslim models work well in Indonesia

Islam is the predominant religion in Indonesia with Muslims representing about 87% of the population. Apps, therefore, tend to display Muslim models in their creatives, so that store visitors can better relate to the app.

For instance, many apps from different categories display women models wearing the hijab, a head covering worn typically by Muslim women.

Muslim models are heavily featured in app pages’ creatives as Islam is the first religion of Indonesia.

5. Include small 3D elements in your app screenshots

To enliven screenshots and make them more appealing, include small 3D floating elements. These elements contribute to making screenshots more vivid and giving them a sense of motion.

6. Promotional videos used as TV commercials

By looking at both the top 500 apps and top 500 games in Indonesia, we have found that only a small number of apps (about 24%) have a promotional video, compared to about 54% for games. For apps that have a promotional video, these do not showcase the different functionalities and features of the app but are used as TV commercials instead. Displaying actors talking about the app and using it is a common practice in these TV commercials-like promotional videos.

Bonus tips to localize your app for Indonesia

1. Update your app icon to mark an event

Several events take place every year in Indonesia. It is common practice among apps to update their icon to mark the occasion. They do it by either adding a banner or the date of the event to their icon to indicate their participation in the event.

During seasonal events, for example, apps adorn their icons with a Christmas hat, or hearts for Valentine’s Day, or a soccer shirt for the World Cup. Apps also celebrate their own anniversary with their icon, a common practice in Japan too.

Finally, apps also add elements reminiscent of Islam to their icons in the holy month of Ramadan.

Multiple shopping events occur throughout the year in Indonesia. This is an occasion for shopping apps to boost their downloads and revenue.

Among the most popular shopping events are the Wine Day on 9 September, the Singles’ Day on 11 November (1 represents loneliness and there are four 1’s in 11/11), and the National Online Shopping Day on 12 December.

Shopping apps actively update their icons to draw in-store visitors, showing their participation in sales-linked events.

2. Highlight multiplayer features in your app page

Multiplayer games are very popular in Indonesia. So much so that single player, offline games are the minority. In fact, only 2 in the top 10 free and grossing games do not include any multiplayer component.

All the other games allow you to play with or against your friends or against other players. So, if your game includes multiplayer elements, mention them in your app page.

If you have multiplayer elements in your game, you could showcase them in your app metadata and creatives to appeal to store visitors.

3. E-sports is booming in Indonesia

In 2020, the Indonesian government recognized e-sports as an official sport. E-sports hasn’t stopped growing since then. The country’s gaming culture now prominently features numerous tournaments and leagues.

In its ninth iteration, the Mobile Legends Professional League (MPL), a competition organized around the game Mobile Legends, gathered up to 2,8 million viewers at the same time.

4. Avoid sensitive topics

If you want your app or game to succeed in Indonesia, avoid certain topics. The public negatively perceives anything related to gambling, so tread lightly with this theme.

Take care when showcasing the human body in your screenshots too. Avoid displaying even slightly unclothed models, regardless of their gender, as it could cause problems.


Indonesia, one of the most populous countries in the world, is growing rapidly and its people are receptive to apps and games from non-local developers. This represents an opportunity for apps and games that want to expand worldwide. To successfully localize your app or game in the Indonesian market, here are some valuable tips for you to keep in mind:

  • In Indonesia, people predominantly use Indonesian as a mediation language. It stands as the most utilized language on the Indonesian Play Store. The vast majority of non-local developers translate their app page into Indonesian.
  • Indonesians also use universally understood English words in their everyday language. App pages make the most of it by mixing Indonesian words with English words in their metadata (and creatives), thus targeting words that sometimes have high search volumes.
  • App creatives often feature warm and neon colors, and highlight the cultural diversity of Indonesia. Given Islam is the predominant religion in Indonesia, it’s common practice to feature Muslim models regularly.
  • Indonesian apps extensively highlight promotions and social proofs in their app/game’s feature graphics, screenshots, and promotional videos.
  • Non-local developers, who rarely localize their games beyond translating their app pages into Indonesian, predominantly occupy the top spots on the game charts. This trend presents a significant opportunity for developers willing to invest in thorough localization for the Indonesian market.
  • Multiplayer games and esports are extremely popular in the Indonesian app market. If your game includes one of these two elements, don’t hesitate mentioning it in your app page.
