Statistics

Statistics and records

Submersion turns your logged dives into insight: a single Overview that summarises your whole diving career, ten focused dashboards for deeper analysis, and a Dive Records page for your personal bests. Everything is computed from the dives already in your log — there is nothing to configure.

Note

Where to find it: Open the Statistics destination from the main navigation rail (the bar chart icon). On a phone you land on the list of dashboards; on a tablet or desktop you get a two-pane view with the Overview beside the list. The trophy icon in the top bar opens Dive Records.

How statistics are scoped

Statistics summarise all the dives in your log for the active diver profile. If you keep more than one diver profile (for example, a family member's dives in the same app), the numbers always reflect whichever profile is currently active — switch profiles to see a different set. See Diver-Profile for how profiles work.

Submersion does not offer date-range, site, or buddy filters on the statistics screens: each dashboard is a complete, lifetime view that updates automatically as you add, edit, import, or delete dives. To analyse a single trip or period, use the Trips view or the filters on your Dashboard and dive list instead.

Tip

Statistics need data to work with. The more fields you fill in when logging a dive — depth, time, water temperature, visibility, gas, buddies, equipment — the more of these dashboards come to life. Empty sections simply mean that detail has not been logged yet.

Overview

The Overview is the first item in the Statistics list and the default pane on larger screens. It gives you the whole picture at a glance, in four parts.

Career totals

A grid of headline numbers for your diving career:

Metric	What it shows
Total Dives	Your lifetime dive count
Total Time	Cumulative underwater time, shown as hours and minutes
Max Depth	The deepest you have ever been
Avg Depth	Your average maximum depth across all dives
Dives / Month and Dives / Year	Lifetime averages of how often you dive
Sites Visited	Number of distinct dive sites
Avg Water Temp	Your average logged water temperature

If you have recorded prior experience on your Diver-Profile — dives and time accumulated before you started using Submersion — the Total Dives and Total Time cards add those in and show the split beneath, for example "120 logged + 380 prior". A Diving since line appears when you have set a start year.

Tip

The career totals are the only place where your pre-Submersion dive history appears in statistics. Enter your prior dive count, prior time, and the year you started on the Diver-Profile page so your totals reflect your real experience, not just what you have logged in the app.

Personal records, most visited sites, and distributions

Below the totals, the Overview folds in three more sections:

• Personal Records — a compact summary of your deepest, longest, coldest, and warmest dives. Tap any row to jump straight to that dive. (The full list, including shallowest dive and milestones, lives on the Dive Records page.)
• Most Visited Sites — your top five dive sites by number of dives, each linking to the site.
• Distributions — two pie charts: one breaking your dives down by depth range, the other by dive type (recreational, training, deco, and so on).

The analytics dashboards

Beyond the Overview, Submersion provides nine focused dashboards. On a phone, tap one to open it full screen; on a tablet or desktop, select it from the list to show it in the detail pane. Each dashboard is built from titled cards (most with a short explanatory subtitle), and most cards are interactive charts — tap a point or bar to read its value.

Dashboard	Focus	What you will find
Air Consumption	SAC rates and gas mixes	SAC trend over time, gas-mix breakdown, SAC by tank role, and SAC records
Progression	Depth and time trends	Depth progression, bottom-time trend, dives per year, and cumulative dive count
Conditions	Visibility and temperature	Visibility breakdown, water-type split, entry method, and water temperature by month
Social	Buddies and dive centers	Solo vs buddy dives, top buddies, and top dive centers
Geographic	Countries and regions	Dives per country, per region, and per trip
Marine Life	Species sightings	Species spotted, most-common species, and best sites for marine life
Time Patterns	When you dive	Day of week, time of day, seasonal (by month), and surface interval statistics
Equipment	Gear usage and weight	Most-used gear and your weight trend over time
Profile Analysis	Ascent rates and deco	Average ascent/descent rates, time at depth ranges, and decompression-dive rate

Note

SAC stands for surface air consumption — how fast you breathe your gas, normalised to the surface, so dives at different depths can be compared. Lower is more efficient. See the Glossary for this and other terms.

Air Consumption

Four cards analyse how you breathe your gas:

• SAC trend — your surface air consumption over time, so you can watch it settle as you gain experience.
• Gas mix — how your dives split across air, nitrox, and other mixes.
• SAC by tank role — average consumption broken out by the role a cylinder played (back gas, stage, deco, bailout, sidemount, pony, diluent, and so on), which matters for technical and multi-cylinder dives.
• SAC records — your Best SAC Rate (most efficient) and Highest SAC Rate, each linked to the dive it came from.

Progression

Charts that track how your diving develops: depth progression and bottom-time trend plot those values across your dives, dives per year shows your annual activity, and cumulative dive count traces your total dives climbing over time.

Conditions

How the water has treated you: a visibility breakdown, a water-type split (salt, fresh, brackish), an entry method breakdown (shore, boat, and others), and water temperature by month charting minimum, average, and maximum across the year.

Social

Your diving community: solo vs buddy dives, your top buddies ranked by shared dives, and the dive centers you have dived with most. See Buddies-and-Dive-Centers for how these are recorded.

Geographic

Where you have been diving, as ranked lists: dives per country, dives per region, and dives per trip. Pair this with Trips and Dive-Sites for the full travel picture.

Marine Life

What you have seen underwater: a species spotted count, your most-common species ranked by sightings, and the best sites for marine life ranked by how many different species you logged there. See Marine-Life-and-Photos for logging sightings.

Time Patterns

When you tend to dive: by day of week, by time of day, seasonally (by month), plus surface interval statistics (your average, minimum, and maximum surface intervals between dives).

Equipment

How you use your gear: your most-used gear ranked by dives, and your weight trend — how much weight you carry over time, useful for dialling in buoyancy. See Equipment for managing your kit.

Profile Analysis

Aggregate insight from your dive profiles: average ascent and descent rates, time at depth ranges, and your decompression-dive rate (the share of dives that incurred deco stops).

Tip

Profile Analysis and Air Consumption are the dashboards that benefit most from a recording dive computer. Detailed depth samples sharpen the ascent-rate, time-at-depth, and SAC figures far beyond what hand-entered averages can give.

Dive Records

Tap the trophy icon in the Statistics top bar (or open the Dive Records page) to see your personal bests, each as a card you can tap to open the dive.

Records cover:

Record	The dive with the…
Deepest Dive	greatest maximum depth
Shallowest Dive	smallest maximum depth
Longest Dive	longest runtime, shown in minutes
Coldest Dive	lowest water temperature
Warmest Dive	highest water temperature

Beneath the records, a Milestones section highlights your First Dive and your Most Recent Dive.

Each card shows the dive site, the date, and the dive number where available, and opens that dive when tapped. If you have not logged enough detail yet, Submersion shows a friendly "No Records Yet" placeholder rather than empty cards — the records fill in as you log dives.

Tip

Records and statistics refresh automatically, but if a freshly imported or edited dive has not appeared, use the refresh button in the top bar of the Dive Records page to recompute on the spot.
