Apnealizer
Freedive log and analyzing app
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Dive charts
- The old "Auto Trim" / "Sync Start" button is now called "Align Curves" — you can line up multiple dives by their start, their deepest point, or their end.
- Dive charts now show more helpful markers: ascent point, freefall info, equalization points, and speed-peak counts.
- Chart previews on mobile are cleaner; the detailed markers still show up when you open the full chart.
- Speed controls on the chart are tidier, grouped on one row.
Speed & reliability fixes
- Your dive list loads noticeably faster, especially with a large dive history.
- Fixed a bug where newly imported dives sometimes didn't show up in your list at all.
- Fixed a brief flash of the welcome screen right after logging in.
- Fixed imported dives occasionally getting cut short if the dive computer file ended partway through the ascent.
Account & settings
- Your phone or browser can now save and auto-fill your Apnealizer login.
- Added a "Send Diagnostic Logs" option in Settings, so you can send logs to support if something goes wrong.
Small polish
- Notes no longer visibly change size while you're editing them on mobile.
