Comparisons
Below vs. Scuba Diving Logbook
Below is one of the nicest native dive log apps on the iPhone, and if your whole diving life happens on iOS, it's a genuinely good choice. The comparison comes down to one word: everywhere.
Updated September 3, 2026
What Below does well
Below is a native iOS app with the polish that implies: a beautiful interface, Apple Watch integration, and smooth offline behavior. Dives are logged on the phone, synced through your Apple account, and presented with real care. As an iPhone-first logbook it earns its reputation.
The limits are structural, not quality: it's iOS-only. There's no Android version, no web version, and no way to open your logbook from a desktop browser — reviewing your history on a bigger screen, or from a dive shop's computer, isn't part of the model. If you ever switch platforms, your logbook's home doesn't come with you.
Where Scuba Diving Logbook differs
Scuba Diving Logbook is an online scuba diving logbook that runs in the browser, so the same logbook opens on an iPhone, an Android phone, a tablet, and any desktop — nothing to install, nothing tied to one platform. Logging is built to be as fast as a native app: two required fields, your own choice of every other field, and the form works signed out. Any dive can become a public page you share with one link, and your data is always exportable as a full JSON backup, free.

Which should you pick?
If you're all-in on iPhone and want a native app with Watch support, Below is a fine logbook — we mean that. Pick Scuba Diving Logbook if you want your dives reachable from every device you'll ever own, sharable with buddies on any platform, and stored somewhere a platform switch can't strand. Coming over is easy: export your dives and use the CSV or UDDF import — free on every plan, with a preview before anything is saved.
