How did InApps help Wawa Games?

Wawa Games runs a live arcade app in Indonesia: players steer real claw machines from their phones and win prizes. Its previous vendor had left the app full of bugs, with no documentation. From December 2019 to December 2020, InApps, a software company in Ho Chi Minh City, Vietnam, was its main development team: it fixed the critical issues first, then built new features. Wawa Games' CEO rated InApps 5.0 on Clutch.

About Wawa Games

Wawa Games calls itself Indonesia's first live arcade games app. Players steer real claw machines and other prize machines from their phones, at any hour, earn e-tickets, and redeem them for shopping vouchers or prizes shipped to their door.

The challenge

Wawa Games' previous vendor had not finished the app well. It left bugs, messy code and hidden errors, a long list of critical issues, and no requirements or API documentation: only the source code. The app was live, with players in it, and Wawa Games wanted new features out to grow its downloads.

A live app full of players, and no map of the code underneath it.

The solution

Wawa Games chose InApps after interviews and a two-week trial. We started where the risk was: our engineers went into the live code while our project manager worked with Wawa Games' team on the business behind each problem. We ranked the critical issues, fixed and refactored those first, then built on top: sign-in with Facebook, Google and Line, phone verification, live arcade play, tickets traded for prizes, and HTML5 mini games. The team spoke with Wawa Games every day.

Questions about this project

InApps was the main development team for Wawa Games' live arcade app from December 2019 to December 2020, after a previous vendor left it with buggy code and no documentation. InApps, a software company in Ho Chi Minh City, Vietnam, fixed the critical issues first, then built social and phone sign-in, live arcade play, ticket-for-prize trades and HTML5 mini games.
A live arcade games app from Indonesia, which calls itself the country's first. Players control real claw machines and other prize machines from their phones, earn e-tickets, and redeem them for shopping vouchers or prizes shipped to them. The Android app had more than one million downloads on Google Play in October 2026.
By reading the code and the business side at the same time. Engineers went into the live codebase first, while a project manager worked with Wawa Games' team to understand why each problem mattered. Together they ranked the critical issues, fixed and refactored those first, and only then moved to new features.
Native iOS and Android apps, with React, Node.js and PHP, MySQL as the database, Socket.IO for real-time connections, Redis, and Google Cloud Storage. InApps covered the backend, both native apps and DevOps.
In a verified Clutch review from March 2021, Wawa Games' CEO and founder rated InApps 5.0 for quality, schedule and cost, and wrote: “They are proactive to solve almost every problem we faced.” The review says the InApps team spoke with Wawa Games every day and solved problems quickly.
Yes. Western Indonesia, including Jakarta, runs on the same clock as Vietnam, UTC+7, so the two teams share the whole working day; central and eastern Indonesia are one and two hours ahead. InApps engineers worked on Wawa Games' app from Ho Chi Minh City.
A team joins your project and starts with the code that is already there. A dedicated development team can become your main engineering team, as it did for Wawa Games. When the inherited code needs a full review first, see code audit and remediation; for keeping a live app healthy over time, software maintenance and support.

Inherited an app another vendor left unfinished? Put a team on it, as Wawa Games did.
