iDive is The First Scuba Diving Planning App that calculates your needed Resting-Time between
different dives, AND Without nitrojen groups. At this moment the app version is for scuba diving on air tanks only. All you need to do is insert the requested depth and the bottom time - and THAT IS IT ! You'll get the needed Resting-Time ! Any use of the app is in the user's responsibility, and i would love to hear comments and suggestions for improvement.
Have a nice dive!
