Introduction

介绍

In 2020, Google conducted research that highlighted the negative impact of app sizes on conversion rates, revealing a 1% decrease for every 6MB expansion of the app APK size. This finding prompted Grab to ensure new and existing users had a consistently excellent Grab superapp experience, given the prevalence of low-end devices and disparate internet infrastructure in Southeast Asian regions. As a result, Grab initiated Project Bonsai in Q3 2021, with the goal of reducing and optimising the app size while enhancing user experience, reducing installation barriers, and boosting user acquisition.

2020年，Google进行了一项研究，强调了应用大小对转化率的负面影响，每增加6MB的应用APK大小会导致1%的下降。这一发现促使Grab确保新用户和现有用户在东南亚地区普遍存在低端设备和不同的互联网基础设施的情况下，能够始终拥有卓越的Grab超级应用体验。因此，Grab在2021年第三季度启动了Project Bonsai，旨在减少和优化应用大小，同时提升用户体验，降低安装障碍，增加用户获取。
