Surf Log & Swell Tracker
Direction & Wave Period
$1.99 · Designed for iPad. Not verified for macOS.
Measure the swell yourself — bearing by compass, period by counting sets, height by tilt. Not a forecast. No ads.
Stop guessing which way the swell was running. SwellBearing turns your
iPhone into a logbook for what you actually saw at the beach.
RECORD
- Point your phone at the sea and log the swell bearing with the compass
- Count the sets: tap as each wave passes and get the period in seconds
- Measure wave height with your phone's tilt — aim at trough and crest
- Speed and wavelength are worked out from your period (deep-water physics)
- Rate the size the way surfers actually talk about it: S / M / L / XL
- Add photos or a video and a note, right on the record screen
REVIEW
- See every session pinned on a map, coloured by size
- Browse your log like a logbook, newest first
- A rose chart shows the bearing pattern across your whole log
HONEST ABOUT WHAT IT SHOWS
- No forecasts, no predictions — only what you measured, when you measured it
- Wave height appears as a number only when you measured it yourself
- Speed and wavelength are clearly labelled as deep-water values
- Works completely offline, nothing leaves your device
One purchase, everything included, forever.
