Dive Gas SAC Log2026

Dive Gas Log is an offline utility for recreational divers, boat dives, training reviews, and personal dive records. Enter tank size, starting pressure, ending pressure, average depth, dive time, site, and gear notes to calculate SAC and RMV gas consumption. Save common tank templates, compare past dives, and estimate usable time with a reserve pressure. The app requires no login, no internet connection, and no data collection. All dive logs and calculations remain stored locally on your device, making it useful for post-dive review and safer future planning.
