Apnealizer is the freediving logbook built for serious athletes. Import your dives, analyze every detail, and track the progress that actually moves your personal bests.

IMPORT DIVES FROM OTHER APPS Sync from Garmin, Suunto, and ATMOS dive computers apps. Import older gear via the desktop sync app. Your logbook stays complete — no manual entry.

ANALYZE AND COMPARE DIVES Dive profile charts plot depth, speed, and temperature for every dive. Overlay dives side by side to spot what's changing between sessions. Count strokes and pulls in FIM and CNF dives. Predict future performance based on your training trends.

THE NERD SHEET An Excel-like table of all your dives — filterable, annotatable, and built for deep analysis. Mark rows, add notes, and cut through your data to find exactly what you're looking for.

STAY ORGANIZED The dive calendar gives a clear overview of your full training history. Tag dives by session focus, buddy, or conditions. Track locations so you always remember where you trained.

TRACK WHAT MATTERS Personal bests tracked automatically across all disciplines. Charts and statistics reveal your long-term progress. Dive metrics let you log soft performance indicators after each dive — capturing the subjective side of your training alongside the numbers.

SHARE AND EXPORT Share any dive profile with a coach or training partner via link. Create social media cards and videos directly from your charts — ready to post.

Apnealizer is free to use. Upgrade to Pro to unlock advanced analysis and unlimited cloud sync.
