Krakentools – Dive Calculators, Logbook & Planner

The professional dive toolbox for ambitious recreational divers and technical divers. Krakentools combines over 22 specialized dive calculators, a complete digital logbook and powerful planning tools in a single app – fully offline and available in 89 languages.

Krakentools was built by divers for divers – independent, with no ties to any manufacturer. A neutral toolbox designed to support you in planning and documenting your dives.

Plan recreational dives within no-decompression limits, run complex decompression plans using the Bühlmann ZH-L16C algorithm or calculate multilevel dives with multiple gas switches – precise results in seconds. Load preconfigured equipment setups, calculate gas mixes and check safety parameters like CNS/OTU, minimum gas and rock bottom in one seamless workflow.

Connect your dive computer directly via Bluetooth – Shearwater, Suunto, Garmin, Mares and many more. Download your complete logbook wirelessly and store dive profiles with depth curves in your personal dive record. No cable, no PC, no detours.

Share your experiences: Krakentools creates attractive social media cards from your dive data for Instagram, WhatsApp and other platforms – featuring depth, time and your personal dive stamp.

With UW Color Fix you bring the true colors back to your underwater photos – the tool corrects the blue and green cast caused by water and shows you what the scene really looked like.
