0022901

Initial release: 2024

Mobile app

In 2024, the government of Benin Republic enforced the addition of the 01 prefix to all existing phone numbers. In order to facilitate the migration of numbers in users’ contact list, I decided to develop this open-source application that allows anyone to compile the APK themselves and migrate numbers. The reason behind this choice is to avoid potential data leaks/theft when using third-party applications. The source code is made available transparently.

🧰 Tech stack

  • Languages: Kotlin
