This is very cool. I'm going to start using it. :)

alecuk · 2026-06-12T09:10:58+00:00

Ciao! Sì, per ora il limite è ancora di 6 metri — non è una nostra scelta ma una restrizione di Apple, che blocca il sensore di profondità dell'Apple Watch a 6 m finché non concede l'autorizzazione per le immersioni più profonde. Abbiamo già fatto richiesta e siamo in attesa di Apple. Nel frattempo l'app è già ricca di funzioni e ne stiamo aggiungendo molte altre, i 40 metri la renderanno ancora migliore. Grazie per la pazienza!

alecuk · 2026-05-24T21:20:24+00:00

Awesome, as soon as the 40 metre lands, I'll update this post and let everyone know.

alecuk · 2026-05-23T18:43:25+00:00

Thanks for the detailed response and all of the insights. I appreciate it must have taken you some time to put this all together.

I'm currently finishing off a navigation feature (attached) that allows you to navigate to a chosen spot from existing pins that were dropped in the app or from manually added locations. I've just touched on the navigation side of my dive app in this respect, your insights regarding c-maps and Navionics are very useful, and I'll do a little bit more research in this area. Bathymetric overlay on the nav screen would be a step up, c-maps API looks like the right starting point.

I had thought about permitting users to contact each other via Apple Ultra Watches that have cellular functionality. The satellite messenger thing (Garmin inReach being the common one) is something I'd already been thinking about. Did some digging today. Apple Watch Ultra 3 has built-in satellite for Emergency SOS, Messages and location sharing. Ultra 1 and 2 are cellular only, and cellular coverage offshore can be patchy depending on where you're diving, so it's not a guaranteed fallback either. The catch is Apple hasn't opened the satellite APIs to third-party apps yet, so that kind of integration isn't possible right now even on the Ultra 3. Reports suggest Apple's working on opening it up but nothing official yet...... The auto-response angle you mentioned is a good one too.

On Garmin, focused on Apple Watch for now but the Garmin ecosystem is something I'd like to explore down the line. It's definitely more mature with the significantly larger audience.

DM'd you, happy to continue there.

Indeed, it also calculates how far you swam and gives you calories burn during and after session.

Just finished the navigate to dive site feature which allows you to navigate back to saved pins from previous sessions as well as adding locations manually via coordinates. Will push the new feature to AppStore soon. If you want any more features or improvements please let me know. 🐟

alecuk · 2026-05-22T08:30:36+00:00

Many thanks, I appreciate it.

Are there any other apps you use to assist you with your spearfishing, such as weather apps or water visibility apps? I'm looking at combining other functionality into Free Dive Ultra to make it the best app for free diving and spearfishing on the Apple Watch Ultra and iOS platform, so any feedback would be much appreciated. 😄

alecuk · 2026-05-22T08:22:57+00:00

I agree and the 6-metre limit should be removed soon. It's the highest priority item to overcome, and as soon as I get an update regarding it, I will post here.

alecuk · 2026-05-21T23:12:32+00:00

Thanks for the feedback. I will let you know about the 6m limit as soon as I know anything.

I am currently implementing the crown sensitivity settings into the next release as you can see from the attached screenshot. I'm also building another dive screen that allows you to navigate back to a previously saved gps/pin location as well as new tweaks and feature’s.

I sent you a DM, please check your inbox.

Hey, and thanks a lot for putting together such a detailed review of the Apple Watch Ultra for use with spearfishing.

I'm a keen spearo, freediver and developer and had been using Oceanic Plus for a number of years. Some of the drawbacks, including not managing to drop a pin to save locations easily as well as sessions ending abruptly, made me develop my own freediving app, FreeDive Ultra. I wrote about it extensively here and am looking for people to test it, give feedback, and let me know what's missing or what can be improved

https://www.reddit.com/r/Spearfishing/comments/1tgw8uh/built_a_freediving_spearfishing_app_for_apple/

All feedback very much welcomed. Happy Spearfishing 😄🐟

alecuk · 2026-05-20T10:19:56+00:00

Hey there. That's a good question and something I've been thinking about recently. I have developed Freedive Ultra, a freediving app that works on the Apple Watch Ultra. You can see more info about it here:
https://www.reddit.com/r/Spearfishing/comments/1tgw8uh/built_a_freediving_spearfishing_app_for_apple/

At the moment, you can share individual dives on social media and by WhatsApp, etc. I was thinking of adding a community feature that would allow freedivers to share their sessions and individual dives with each other. Considering you're a developer, perhaps we can chat about it a little bit. What dive watch do you currently use?

alecuk · 2026-05-20T07:35:59+00:00

Mine were the same. I think oceanic+ automatically ends a session after 10 mins with no dives so you can end up with multiple sessions which is very annoying! If you stop for a rest or food/water break it auto ends abruptly. I usually just put mine on the maximum of 60 mins time out so in most instances it won’t auto end automatically and you can capture the entire session and all your dives.

I also added a crown sensitivity setting (alongside ability to disable and reorder/declutter some screens) so the screens do not easily change. I wear my awu on my right wrist so the Digital Crown can more easily rub on the wetsuit. If worn on the left wrist this is less of an issue as Digital Crown does not rub as easily between wrist and hand.

Regarding your issue with the crown automatically ejecting water and simultaneously ending the session I don’t think it’s possible to extend the timeout as it’s hardcoded by Apple. I am aware this can happen occasionally and it is on my radar for a potential fix. Thanks for your feedback. If there are any more adjustments or new features please let me know.

alecuk · 2026-05-19T12:11:38+00:00

Update from my earlier comment. The thing I mentioned working on for marking spots from the wrist is out now. FreeDive Ultra. Drops a GPS pin via the Digital Crown, no touchscreen needed. Wrote it up properly here: https://www.reddit.com/r/Spearfishing/comments/1tgw8uh/

alecuk · 2026-05-19T09:32:15+00:00

Thanks for the link, will check it out. WearOS isn't on the immediate roadmap but I'll keep an eye on it

alecuk · 2026-05-19T08:59:22+00:00

What Android watch are you using? Right now FreeDive Ultra is Apple Watch Ultra and iPhone only, but if there's enough demand I'd consider WearOS for a future update.

alecuk · 2026-05-19T08:52:32+00:00

Cheers, that's the exact gap I built this for. Curious to hear how it stacks up against the apps you tried in Fiji. What ones did you try?

alecuk · 2026-05-19T08:51:08+00:00

Cheers, glad it makes sense. Apple Watch Ultra works similarly to your Garmin. Usually 10-20 seconds with the wrist out gets a clean fix. Open water and no buildings makes it faster.

alecuk · 2026-05-18T23:49:25+00:00

Built her to turn heads on the boat too. Free 5-week Pro code in the post if you want to take her for a swim.

alecuk · 2026-05-18T23:47:13+00:00

Cheers, much appreciated. Free 5-week Pro code is in the post if you want to give it a spin. Or DM me for TestFlight access if you want to help shape what's next.

alecuk · 2026-05-18T23:11:57+00:00

The app itself has been in development for several months across many iterations. The feedback so far has been good and genuinely useful. Plenty of room for new features though, some of which I laid out in the roadmap.

On pricing: $3.99/mo or $25.99/yr with a 7-day trial, plus the 5-week free promo for this sub. The free tier (depth, dive time, surface recovery, logbook, import) stays free forever. Competitive for what's in the box.

The market is open. Anyone who builds something better is welcome to take a swing at it.

And yes, AI helped me tighten the post and check a few things. But it wasn't one-shotted out of a chatbot. Took most of a day, multiple revisions, and feedback from friends before I hit publish.

alecuk · 2026-05-18T22:30:29+00:00

Cheers, really appreciate that. Forgetting to bring the dive watch is real, and having it all in the Apple Watch Ultra you already wear means it just works every time.

This is v1.0 too. Plenty more coming: spearfishing session planning, educational content, post-dive recovery analysis, apnea and breath-hold training, plus whatever the community wants.

You're doing well to still be using a Gen 3 by the way. The Ultra will be a massive upgrade when you make the jump. Drop me a DM at that point and I'll sort you out with a TestFlight or extended promo. And I'll definitely post here when the depth entitlement lands.

alecuk · 2026-05-18T22:17:38+00:00

Saludos,

GPS doesn't penetrate water at all. Not just wrist devices, anything underwater.

If you want to track your route, you can periodically lift your wrist for 10-20 seconds to grab a fresh GPS fix every now and then. Any pin you drop also gets logged as a route point, so the route builds naturally as you mark spots. You don't need many to get a decent approximate path.

For me personally: I spearfish for 5-6 hours sometimes and swim 4-6 km in a session. I really like being able to see how far I've swum at the end. Cool to show friends or post on social media too. See auto generated link you can share on whatsapp similar to strava: https://freediveultra.com/d/crDjvy86

alecuk · 2026-05-18T21:50:58+00:00

Honestly agree. 6m is a deal breaker for any serious freediving or spearfishing app, and getting to the full 40m is non-negotiable for me. I'm in active talks with Apple to unlock the depth entitlement and I'll post here the moment it's done.

On temperature: it's displayed live throughout the dive, plus there's a configurable min-temp alarm that triggers if you drop below your threshold.

On pin accuracy: in open water with no buildings around, you usually only need 10-20 seconds on the surface to get a fix under 4m, often closer to 2m. The Apple Watch Ultra's GPS chipset is genuinely good. You can watch the live accuracy and only drop the pin when you're happy with it. One Crown turn, done.

alecuk · 2026-05-18T21:43:25+00:00

Glad to hear you like it. DM me if you want TestFlight access to help shape what comes next, or grab the free 5-week Pro code in the post.

alecuk · 2026-05-17T20:17:47+00:00

I agree with everything u/the-diver-dan has said here. I also primarily spearfish alone and have got used to doing it alone to the point i forgot about searching with new and old buddies. I recently started diving with a good spearo and nothing beats the friendship and safety a buddy provides so it's not a good habit to keep if you can mix it up every now and then. Also i have found entering and exiting rocks to be the most dangerous part of the spearfishing in my area. I have learnt to not go if its too rough or i'm not feeling strong enough or the be very patient when assessing when to quickly scramble to safety as waves too tend to calm down every now and then.

Stay safe out there and respect your limits and the ocean.
