GB WhatsApp demonstrates strong strengths in theme customization. Its theme repository has a capacity of 3.2 million pieces of data (2025 data), which is much higher than the 12,000 pieces of data of the official WhatsApp. Additionally, it supports dynamic real-time rendering technology, and users’ average daily frequency of theme changes is 4.7 times (0.3 times for the official app). According to a 2025 survey by The Economist, the underlying cause why 89% of consumers in countries such as Brazil and India prefer GB WhatsApp is the “deep interface transformation”, for instance, the ability to customize the transparency of the chat window (0%-100%), font size (8pt-32pt), and bubble shape (12 geometric parameters). However, the official application only allows fine-tuning the base color temperature and background image. In 2024, Indonesian students reduced their daily average mobile phone use by 23% with the “Time-based themes” feature of GB WhatsApp (e.g., automatically switching the study mode to the black and white minimalist theme), indirectly improving their academic efficiency.
Technological openness is the differentiating factor. GB WhatsApp offers the feature of editing the UI resource packages of APK files directly and managing color parameters with precision (0.0001) through Hex code, while the official app simply opens hexadecimal preset values. Statistics from the global developer community in 2025 show that third-party Theme tools based on GB WhatsApp (such as Theme Studio Pro) have crossed over 450,000 combination parameters. The download volume of a single hit theme has gone past 18 million times, and the commission rate for creators has gone past $0.8 per item. Take, for instance, the “Neon Cyber 2.0” theme developed by South Korean designer Kim Joon, which earned $340,000 in its first week on GB WhatsApp. Its dynamic light and shadow effect (60 frames per second) improved the scrolling smoothness of the message list by 19% and reduced the memory usage rate to 42MB (78MB for the official theme of the same type).
Hardware adaptation capabilities make it more fun. GB WhatsApp’s theme engine can automatically optimize the rendering load based on the device’s GPU performance. On high-end chips such as Mediatek Dimensity 9400, the switching speed of the dynamic theme can reach up to 0.2 seconds (the official standard is 0.7 seconds), and on low-end mobile phones (such as Samsung A05s), it can also support an animation frame rate of 55fps (±3% fluctuation). The 2025 DisplayMate test showed that its “AMOLED Power-saving theme” could reduce the screen’s power consumption from 420mW to 290mW and increase the phone’s battery life by 1.8 hours. Other than that, its theme file compression algorithm (LZ4+Zstandard mixed encoding) reduced the size of one package of themes to a mean of 1.3MB (official size: 4.7MB). Where there is costly traffic such as in Nigeria, the users save around $1.2 per month in data fees.
There is the environment of the market that forms a moat. GB WhatsApp has joined hands with 160 Design Academies worldwide to bring in licensed theme stores. Over 90,000 pieces will be uploaded by 2025, and their review pass rate will only be 7.2%, all in a quest to balance looks and functionality. For instance, the “ErgoVision” theme created by Politecnico di Milano, based on the model of human eye focus, reduces reading fatigue index by 37% and won the Red Dot Design Award in 2025. However, there are dangers as well: Security firm Kaspersky found that 23% of third-party theme packages include tracking codes capable of stealing users’ input patterns (sampling 12 times a second), adding up to more than 120,000 complaints about data privacy leak in Brazil by 2025. Nevertheless, the “sandbox operation mode” of GB WhatsApp can increase the isolation degree of topic permissions to 89%, which is much higher than the 52% of the official app, becoming the favorite platform for users with customized requirements.
