Made for iPhone Duo. Unfold it and the app opens like a book. The list you chose from stays on one side of the fold, and what you chose opens on the other: all the fishes on one side, bony fishes on the other. One tap deeper, and the whole family sits beside the species you are reading about. Pick another and only that half changes. The rest works the same way. A dive site sits next to the other sites in its town, a dive centre next to its neighbours, an article next to the journal, a marine day next to the calendar, and the sea conditions next to every station on the coast. Lists fall into two columns that meet exactly at the crease. The crease no longer runs through the middle of a photograph. That was the first thing we saw on an unfolded Duo, a fish folded in half, and everything above comes from not wanting to see it again. Navigation waits beside the camera, where the folded phone keeps it. Folded shut, the cover screen is simply your iPhone. Below deck: the journal cards on Discover are now the same size as everything around them. See you in the water.

Every species, dive site and dive centre is now in the iPhone's own search. Swipe down on the home screen, start typing a name - the common one or the Latin one - and the answer is there with its photograph before the app has opened. Siri answers about the sea without opening anything at all. "Sea conditions in Red Sea" gives you the water and the air, the wind, the wave and what thickness of wetsuit. Five more phrases open FishID, the hazards list, or any species, site or centre by name, and all six work inside an automation. Two tiles for Control Center: FishID, and the water temperature in your city. Both go on the Lock Screen or the Action button - the version that matters when you have just surfaced and your hands are wet. The species page got out of its own way. The photograph is bigger, and like, save, comment and add-a-photo sit under the name instead of at the far bottom, where nobody found them. And a clear night finally shows a moon. It was a yellow sun at midnight - the sort of thing you notice once and then cannot stop noticing. Below deck: covers stopped jumping while they load. See you in the water.

A large family used to open as one long wall of cards. Now it sorts itself by genus. Open the wrasses, the groupers or the scorpionfishes and the species arrive in named groups, most of them with a line under the heading explaining what actually holds that group together. That is the division you already carry with you underwater. Someone looking for a Phyllidia is looking for a word, not flipping through pictures hoping to recognise one on the way past. Grouping now starts on smaller categories than before, which is where it was missing most: the pages you open with a name already in mind rather than time to browse. Below deck: edges sanded, bolts tightened. See you in the water.

Weather you can plan a dive around. Tap the weather card and the whole picture opens: temperature, wind, waves and tide hour by hour, the days ahead, and the two days behind you. Those two decide more than the forecast does. If it blew hard on Monday, Wednesday still owes you a cloud of sand, however calm the morning looks. The same tap now works from a dive site and from the widget on your home screen. FishID has learned to warn you. When the answer is something you should not touch, it says so under the name, instead of waiting for you to open the card and find out. Missed the last one? You can send a photo to FishID straight from Photos: Share, then Identify with FishID, and the answer comes back without you leaving the gallery. Video goes through too. Below deck: edges sanded, bolts tightened. See you in the water.

Prices you can actually read. A dive course in Jordan comes listed at 350 JOD, and unless you live there that number means nothing at all. Now it also says about $490, in dollars, euros or pounds, whichever your phone speaks. It is a rough figure and not a quote: rates drift, and plenty of centers set their own dollar price that owes nothing to the official one. Enough, though, to tell a bargain from a splurge before you write to anybody. Missed the last one? FishID has been naming fish from your photos for a while, and since the previous update it takes video as well: drop in a dive clip and it hands back the frames worth arguing about, already sorted out of the blue. Below deck: edges sanded, bolts tightened. See you in the water.

Feed FishID your video. Go on. That two-minute clip: blue, blue, a lionfish, blue, and something orange that left before your camera woke up. Drop it in. The app chews through the lot right there on your phone, spots every place the picture changes and hands you the frames worth arguing about: lionfish at the top, pufferfish four minutes deep. Tap one, get a name. Tap the same one tomorrow and it is still free, because answered frames stay answered. Big categories finally fall in line. A hundred and fifty nudibranchs used to hit you as one glorious wall of slime; now they queue up by genus, each lot with a note on what makes it worth a second look. Below deck: edges sanded, bolts tightened, a few things made quicker. See you in the water.

FishID: find out what you just photographed. Pick an underwater shot from your library and we compare it against every species in the guide - photographs taken in the Red Sea, not aquarium stock. You get the closest matches with a confidence figure, each opening its full card: size, habits, and whether it is one to keep your distance from. Blurry, backlit, half a fish behind a coral head - that is what underwater photography looks like, and the answer is often still right. Five identifications a month are free. If you need more there are packs that never expire and a subscription for regular divers, and what you buy belongs to your account rather than to the phone. FishID has its own place in the tab bar now, and Read has moved into More. Search understands descriptions too: try "white fish black stripe yellow tail" when the name escapes you. Thanks for diving in with us!

The guide has always used the real words - nematocyst, verrucotoxin, protogynous hermaphrodite. This version explains them. A glossary of two dozen terms, written for a diver rather than for a biologist. Why a jellyfish that has been dead on the sand for a day still stings. Why a boxfish can afford to let you get that close. What is actually happening when a fish "changes sex", and why the largest clownfish in an anemone is always the female. Every entry that describes something that can hurt you now ends with what to do in the first minutes - including the cases where the right move is the opposite of what people usually do. Hot water, not ice, for a stonefish spine, because that venom is a protein and heat takes it apart. Never fresh water on a jellyfish sting, because it sets off the stinging cells still sitting on the skin. It is first aid for the time it takes to reach a doctor, not a replacement for one. And you no longer have to go looking. A species page now shows the terms its own description uses: read that a boxfish releases ostracitoxin, tap the word, and the explanation opens over the page without losing your place. Thanks for diving in with us!

Two new things on a species page, and a fix to who gets the credit. How an animal breeds. Whether it scatters its eggs into open water, hides them in a nest, carries them in its mouth or gives birth to live young. Whether it stays one sex for life, or starts male and turns female later - which is the ordinary thing to do for a clownfish, and the reason the biggest one in an anemone is always the mother. Every term comes with a line of plain language underneath. Where the name comes from. That unpronounceable Latin is usually a description, once you know which words it is built from. A crab that walks around holding anemones in its claws is named after the leather glove of a Roman boxer. A lionfish is simply called "soldier". We show the meaning of both halves of the name, and name our source. Also on a page: other names the same animal goes by, grouped by language. And photo credits now follow the photo. A gallery shot by several people used to be signed by one of them; each picture is now credited to whoever took it. The species screen also reads in a better order now: the facts table comes before the long descriptions. Thanks for diving in with us!

Categories now tell you something. Open any group - Fishes, Nudibranchs, Hermit crabs - and you get its photo, its description, its rank in the classification and how many species sit under it. Until now those screens were a grid of tiles and nothing else, even though the text existed on our site all along. Groups we've documented also carry a short "How to recognise" list: the body shape and the two or three marks you actually check underwater to place an animal in the right family. Species pages can now show details the catalogue keeps but the app never displayed - maximum age, diet, when the animal is active, how often divers run into it, the habitat it prefers. Whichever of those we know for a given animal is now there. Thanks for diving in with us!

Videos in articles play again. Some of our stories are built around footage - a drone clip, a shark passing under the boat, a whale calf taking its first breath. Those videos had stopped playing inside the app and showed an error instead. They now play right there in the article, without sending you anywhere else. We also taught the article reader to recognise a couple more link formats, so short-form and privacy-mode video links embedded in a post work like any other. Thanks for diving in with us!

Articles read better now. Blog posts that include tables finally render as proper tables - clean columns and headers, instead of one run-on paragraph. And when an article links to something of ours - a species, a dive site, a centre, or another post - it now opens right here in the app instead of bouncing you out to the browser. You'll also start seeing the occasional partner pick: a dive-gear recommendation from one of our affiliate partners, always labelled as such. They come from us, not an ad network - they use no ad SDK, no advertising ID and no profiling - and they're what keeps Red Sea Creatures free. Thanks for diving in with us!

Know what to watch for on the reef. A new Dangerous Marine Life section brings together the Red Sea's venomous, poisonous, and potentially dangerous species. Filter by threat type, browse them grouped by family, and tap any species for its full profile. There's also a built-in safety guide: how to avoid trouble, first aid for stings and bites, and emergency contacts for dive-medicine centers all along the Red Sea. And there are new sticker packs, too - add our Red Sea creatures to Telegram or WhatsApp and drop them into your chats. Thanks for diving in with us!

Red Sea Creatures now lives in your Messages - and more. Search right inside Messages: find any creature, dive site, dive center, or article without leaving your chat, and send a link your friend can tap to open it in the app or on the web. There's a new sticker pack, too - drop Red Sea creatures into your conversations: green sea turtles, reef octopus, hammerheads, whale sharks, nudibranchs, and divers. Scan an App Clip code - at a dive center or in a printed guide - to open that dive center or dive site instantly, no install needed. And shared links now open right where they should: the exact creature, dive site, dive center, or article, on its own screen in the app. Thanks for diving in with us!

Support the reef - and dive smarter. If the app is useful to you, you can now leave an optional tip and become a "friend of the reef." It unlocks nothing - every feature stays free for everyone - it just helps the guide keep growing. You can also rate the app right from the Discover screen. The Dive map got a big upgrade: sites cluster into a single marker when you zoom out and spread apart as you zoom in, tap any pin for a quick card with its rating and photo, and the map now fills the screen. Dive sites work offline, too - the sites you've opened, and their site maps, stay available without a connection. Handy on the boat. Plus Handoff: the creature, dive site, or article you're reading hands off to your Mac and opens on the web. As always, thanks for diving in with us!

This one's for the bigger screens. Red Sea Creatures now makes the most of iPad. Turn your iPad to landscape and a sidebar puts every section a tap away, with roomier layouts throughout - more species per row, larger photos, and a comfortable reading width for articles. In portrait it's the familiar layout you already know, and it works in every orientation and side by side with other apps. It runs great on Mac, too: on Apple silicon it opens in the same wide sidebar layout, in a resizable window. Articles are nicer to read as well, with proper bulleted and numbered lists, bold and italic text, and bigger images. Plus lots of smaller polish across the app. As always, thanks for diving in with us!

This one's for everyone who's ever wanted to share what they saw down there. You can now add your own photos to any creature. Open a creature, tap "Share your photo," pick a few shots, and send them in. Our team gives every photo a quick look before it goes live, and we'll email you the moment it's approved. Keep track of everything you've shared under More → My Photos: see what's published, what's still under review, and take down anything you change your mind about. We've also made links from our emails and website open right here in the app, on the matching screen, instead of bouncing you out to the browser. As always, thanks for diving in with us!

A few things to make browsing nicer: Full-screen photos are now a proper gallery — just swipe to flip through a creature's photos without closing the viewer every time. Links in articles finally work the way you'd expect — tap one and it opens right inside the app. Photos now fill the screen without awkward cropping, and the occasional sideways shot shows up the right way up. As always, a handful of small fixes and polish. Thanks for diving in!

We've been busy beneath the surface! • Widgets!
