As a free app on the App Store, Oceanic+ will include depth tracking (including depth alarms), GPS tracking, logbook (up to 12 dives), snorkeling, and more.
For more advanced diving options such as No Decompression Limit, users will be required to purchase an Oceanic+ subscription plan ($4.99/day, $9.99/month, or $79/year). Oceanic+ will be available on the App Store later this fall.
