Migration from PRO 1 to PRO2

Mobi Calculator 2.0 is a major new release of the project.

The original version served users well for many years, but its aging codebase became hard to maintain. The app has now been rewritten with a modern architecture to enable faster future development.

What happens to Version 1.0

If you purchased Pro 1.0, nothing changes for you.
  • Your existing app continues to work as before.
  • All features you purchased remain available in that version.
  • You can keep using Pro 1.0 without any changes.
We deeply appreciate the support of our early users, many of whom have been with Mobi Calculator for over a decade.

Moving to Version 2.0

Version 2.0 introduces a redesigned interface, improved performance, and many new features built on a modern foundation. To thank our early supporters, owners of Pro 1.0 will be able to unlock the equivalent features in the new app at a special upgrade price. To use the upgrade:
  1. Install Mobi Calculator 2.0 from Google Play.
  2. Open the new app.
  3. If Pro 1.0 is installed on your device, the app will detect it automatically and offer the upgrade.

Why a new version

The new version is not just an update. It is a complete rebuild of the application, designed to:
  • modernize the codebase
  • improve performance and maintainability
  • enable faster development of new features
  • support future platforms
Our goal was to preserve everything users loved in the original app while creating a stronger foundation for the future. Thank you for supporting Mobi Calculator. Your feedback, reviews, and Pro purchases made this new version possible.
