## What is Dive Exporter?

Dive Exporter lets you download dives from your Bluetooth (BLE) dive computer, view detailed dive profiles with charts, and export them in the standard UDDF format — without committing to a full logbook app.

If you've ever wanted to:

• Pull dives off your computer without installing the vendor's app
• Move data between logging tools
• Keep your own portable UDDF archive
• Manage and download dives from multiple devices

…this is built for exactly that.

KEY FEATURES

• Connect over Bluetooth (BLE) — Shearwater, Halcyon, Mares, Seac, and many other supported brands
• Visualize your dives with a detailed profile chart, including depth, temperature, NDL, PO2, CNS, and decompression info
• Full download, plus Smart download for incremental syncs — only new dives are pulled
• Export to UDDF, the open dive data standard — single dive or bulk
• Manage multiple devices with custom names
• Metric or imperial units, with per-unit overrides
• Bulk delete when you want to clean things up

WHAT THIS APP IS NOT

Dive Exporter is not a dive logbook. It does not try to replace Subsurface, MacDive, or whatever logging tool you already use. It does not store buddies, dive sites, ratings, or photos. Its job is narrower and more reliable: get dives off your computer and into a portable format you can take anywhere.

WHY DIVE EXPORTER EXISTS

Most dive logging apps bundle export with a full logbook experience, and most vendor apps lock you into a single ecosystem. Some vendors don't offer any way to export your dives in a standard format. Dive Exporter fills that gap — a clean bridge between your dive computer and whatever workflow you actually want to use.


## Version history (last 5 releases)

### 1.3.1 — 2026-08-01

A short surface interval after 1.3. Here's what's new in 1.3.1:

- The intermittent timeouts on the Halcyon Symbios are fixed, and the app now works with the newer firmware (V2.36.11), which had changed how the device answers at the start of a download. Downloads are quicker too.
- The Shearwater Perdix 3 and Peregrine (including the Peregrine TX) now carry the verified badge in the supported devices list, after testing on real hardware.
- Settings now opens as a short list of sections, all individual settings have been reclassified.

Small round, easy update. See you in the water.

### 1.3 — 2026-07-15

Back on the surface with our biggest device round yet. Here's what's new in 1.3:

• Perdix 3, now aboard. The Shearwater Perdix 3 is supported for the first time. You can scan for it, connect, and download every dive from first to last. Huge thanks to everyone who tested it on real hardware.
• Steadier Symbios downloads. The Halcyon Symbios now downloads with far fewer of those intermittent timeouts, and the progress counter finally counts straight.
• Shearwater downloads that go the distance. Fixed the "Invalid packet header" error that could cut a download short on Shearwater computers across the board (Perdix, Petrel, and others), so your logs come ashore in one piece.
• More on the profile chart. Your dive profile now plots heart rate as its own series when your computer recorded it, and marks every gas switch with a labeled line (e.g. NX 32) at the moment your breathing mix changes.
• GPS, sample by sample. For GPS-capable computers like the Halcyon Symbios, you can now see the fix recorded with each individual sample, not just one spot for the whole dive. Your UDDF export now writes the dive's location as a proper dive site, so your logbook app can drop it on the map. Dives at the same spot share one site.
• A little buzz. Your phone now gives a short haptic tap when a download finishes or fails, and the start buzz waits until dive data actually begins transferring rather than the instant you connect.
• Sharper UDDF exports. CNS is now written as a fraction (e.g. 0.43) to match the UDDF 3.2.3 spec, so it reads correctly in your logbook app.

Two devices worth exercising this round: the Halcyon Symbios and the newly added Perdix 3. Run a download, send feedback, and if you know anyone with a Perdix 3, point them our way. See you in the water.

### 1.2 — 2026-06-15

• Jot it down: every dive now has a Notes section in the dive detail. Tap it, write something memorable, and check your words survive a UDDF export and re-import.
• Depth at a glance: dive rows now show max depth on the right, in both the Dives list and the download list. Older dives are backfilled automatically, so make sure yours show sensible numbers.
• A newer spec under the hood: UDDF exports now conform to 3.2.3, with heart rate written in beats per second. If your logbook app imports our files, give it a spin and tell us how it goes.
• A tidier dive detail: Dive Mode now lives in the Summary section after Timezone, and "Deco Model" is now "Decompression". Shout if anything looks out of place.

### 1.1 — 2026-05-26

- Avg depth, surfaced. Your dive profile now shows average depth, as a dashed line right on the chart, and as an "Avg Depth (at exit)" row in the dive summary. We'll use your computer's own number when it reports one, and crunch it from the samples when it doesn't.
- Time zones, finally on local time. Dives now keep the time zone your computer recorded, so timestamps show in the zone you actually dove in, with the GMT offset tagged on (e.g. 10:30:00 +0200) when it's different from where you are now. The same offset rides along in your UDDF export.
- A tidier download deck. Fresh dives now land at the top of the download list instead of the bottom, with a cleaner plain-list look that matches the rest of the app.
- Devices in order. Your device list is now sorted alphabetically by name, easier to find your gear.
- Release notes in reach. A new Release Notes link in About takes you straight to the full list at diveexporter.app/releases.

### 1.0 — 2026-05-22
