Our buddy Mauricio over at BlackBerryRocks spotted a new free calculator for all your Storm users. It is a HP25 Scientific Calculator emulator that the developer Dougbert ported over from this original. Nothing crazy and it may not be as good as the gWhiz free calculators, but it’s good to have options.
You can find details about the application on its product page at this link. An OTA install link is also available here. Keep in mind that this is a project that is in development, so a backup and other precautions may be in order.
