Once a trip is on file, home checks everything else in the app against it and lists what isn’t ready. Rows under what the shop needs are things a dive shop can turn you away for, and they decide whether your paperwork reads as ready. Rows under your own kit are worth doing but never hold anything up.

What the shop needs

These are the checks that block your paperwork. Each open row opens the page that fixes it. The nine essentials are bcd, regulator, octopus, tank, weightbelt, pressure gauge, computer, mask and fins. Under the row, home names the ones still open and reminds you that borrowing counts as your own. A tank the shop supplies counts as rented. When a check passes, it turns into a ticked line at the bottom of the group: insurance covers your trip, certifications are on file, your essentials are marked, rental sizes recorded and, once your bag is done, checklist packed. A short tip under the heading explains the group the first time you see it. It goes away once you act on a row, or when you tap dismiss.

Your paperwork button

The foot of home shows log a dive and a paperwork button:
  • paperwork · not ready yet while any row under what the shop needs (other than the refresher) is open.
  • send your paperwork once they’re all clear.
Both open the paperwork page. See Send your paperwork.

Insurance and your return date

Home compares your insurance with the day you come home, not with today. A policy that runs out halfway through the trip covers none of the diving after that day, so home flags it while you can still renew. If you have no insurance on file, home says nothing about insurance at all. When the insurance row is open, it leads the group in bold. It also turns the paperwork button to paperwork · not ready yet, but the paperwork page itself doesn’t check insurance. That page can say ready to send while home says not ready because of insurance. With more than one policy on file, home reads the one with the earliest expiry date, including a policy that has already run out. An old policy you’ve since renewed can make home say your insurance has expired even though the new one is valid. Edit or remove the old policy in Certifications and insurance to clear it.

Refresher

Many dive shops ask for a refresher if you haven’t dived in a year. Home works this out from the most recent dive date in your logbook.
  • With a trip on file, the row appears under what the shop needs when your last dive will be more than a year old on the day you leave. It reads, for example, last dive 14 months ago, with most shops will ask for a refresher before you dive beneath it. It only starts showing once your last dive is about nine months behind you, and it’s hidden while you’re on the trip.
  • With no trip on file, home shows it under meanwhile in two stages: from about nine months (many shops ask for a refresher after a year out) and again after a year (most shops will ask for a refresher before you dive).
The refresher is advice. It never makes your paperwork not ready, because each shop decides for itself. Nothing in the app clears it except logging a newer dive.
You can dismiss the refresher only on the no-trip page, with dismiss on its row. It stays hidden for 90 days, on this phone only. Dismissing the nine-month notice doesn’t hide the one-year notice when it arrives. With a trip on file the row can’t be dismissed.
A dive date the app can’t read, or an empty logbook, never triggers a refresher row.

Your own kit

  • Packing. For example 9 of 14 packed. It counts the gear you’re packing plus your custom items, not rentals, the same way the packing list does. Tap it to open the list. It shows only once your list has something on it.
  • Gear service. From your gear list: regulator is due for service when a service date is within 30 days, or regulator is overdue for service once it has passed. With several items it gives a count instead, for example 2 items are overdue for service. Overdue items take priority: if anything is overdue, the row counts only those. Tap it to open the gear list.
Gear service is measured against today, not against your trip dates.

Water temperature

For a trip ahead, home looks up the sea temperature at your destination and shows it with your trip.
  • Leaving this month, or next month once there are two weeks or less left in this one, it shows a satellite reading from the last few days, labelled water now, when one is available.
  • Otherwise, it shows the average for your departure month, labelled with the month, for example march: typical water. It’s a ten-year average from the same NOAA Coral Reef Watch satellite data.
Under the temperature, home looks through your own logbook for dives at about that temperature and tells you what you wore, for example “you wore 3 mm on 4 dives this warm”, with how you said it felt (you were cold, it felt about right or you were too warm). This is a memory from your logbook, not a recommendation. Tap the temperature to open Zenfinder at that water temperature for a suggestion. The temperature uses the same °C or °F as Zenfinder. It needs a connection to look up, though a recent reading stays on screen if the lookup fails.
Home recognizes 46 dive destinations and some common names within them (for example “Sharm el Sheikh”, “Cairns” or “Tulamben”). A trip whose destination doesn’t match any of them simply shows no temperature.Raja Ampat, Maldives, Similan Islands, Komodo, Bali, Great Barrier Reef, Cozumel, Belize, Red Sea, Galapagos, Palau, Truk Lagoon, Fiji, Hawaii, Philippines, Thailand, Bonaire, Bahamas, Florida Keys, Canary Islands, Malta, Azores, Socorro, Sipadan, Seychelles, Mozambique, South Africa, Iceland, Norway, California, British Columbia, Mexico cenotes, Costa Rica, Indonesia, Papua New Guinea, Vanuatu, Solomon Islands, Jordan, Oman, Sri Lanka, Myanmar, Japan, Greece, Croatia, Sardinia, Caribbean.A more specific name wins, so “Komodo, Indonesia” reads Komodo’s water, not Indonesia’s.

While you’re away and after

During the trip, home says you’re on your trip in place of the countdown. The checks keep running, except the refresher. For a week after your back date, home switches to logging your dives and a reminder to rinse your own gear (see Add a trip).
