Active Log

Active Log is an independent dive logbook and planning app for scuba diving, technical diving, and freediving. Keep your dive history, planning tools, training, and progress together—without depending on a specific dive-computer brand or software ecosystem.

Import existing dive data from supported formats such as Subsurface/SSRF and FIT, or export and import dives in JSON format.

YOUR DIVES, ANYWHERE

Active Log works offline, so your logbook remains available on the boat, at the dive site, or while travelling. Your dives can also be securely stored in the cloud and accessed across multiple devices.

Log your dives. Plan what comes next. Train with purpose.

Every dive. Every breath. One logbook.
