I have created an Android application to help with Nitrox calculations. The application should run on any Android device. It is designed to help facilitate the calculation, and in no means replace training.
If you would like to have a look the two versions can be found at:
Free version-> https://play.google.com/store/apps/details?id=com.gayven.nitroxbuddyfree&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5nYXl2ZW4ubml0cm94YnVkZHlmcmVlIl0
Paid Version-> https://play.google.com/store/apps/details?id=com.gayven.nitroxbuddy&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5nYXl2ZW4ubml0cm94YnVkZHkiXQ
While you use the application if you find any problems, please do not hesitate to contact me. If you find problem with the translation I would gladly fix them as well. The application is available in English, French, Spanish and Portuguese.
