### 4/5 — Love Subsurface but it needs an update per iOS

*2021-07-10, version 3.2.1*

Will an update be coming out soon?  iOS keeps wanting me to delete/keep it since it needs an update since the last iOS update.

### 3/5 — Needs work

*2020-03-26, version 2.2.3*

Not as stable as the Windows version, it seems to have issues replicating data synced from cloud storage. Occasional crashes, and it could do with better cloud sync. 

But a good companion to the full version.

### 4/5 — Finally have decent dive software

*2019-12-26, version 2.2.3*

After being frustrated with the Aqualung dive software and the MySSI software I decided to give Subsurface a try.  I am very impressed.  I use it on my iPhone, MacBook Pro and my Dell laptop running Windows 10.  Using the cloud based storage all three stay synced with each other.  Being able to import and export in multiple formats is a huge plus. 
One of my favorite features is when I add a picture of the mooring site I took before the start of the dive, Subsurface will pull in the GPS coordinates out out the pictures EXIF.  This makes creating dive sites in the log incredibly easy.  I was able export the dive site and send them to my wife which made her logging very simple. 
Read the manual.  There is so much this software can do. 
Things I would like to see improved upon:
Exporting to other platforms like mySSI. 
Being able set a default gear setup.  Tanks, suit etc.  
frame sizing on the Windows platform has some issues.  
Manual could use some work. 

Being Open Source I’m sure many features with be added.  
Thank you developers for creating this wonderful piece of software.

### 4/5 — Good dive logs management and syncing with desktop

*2019-10-29, version 2.1.6*

Couple of minor niggles in the UI but overall really good. 

Let’s you download your dives directly to mobile app or to your pc/Mac/Linux desktop and sync with your phone. 

Auto gps tagging of dive sites is cool too. 
Oh and it’s free :)

### 4/5 — Good app

*2019-10-08*

Great app, but it would be even better if it showed you some more things such as total time underwater, maximum depth I’ve ever dived and longest dive i’ve made.

### 4/5 — Awesome for a free dive log

*2019-03-19, version 2.1.6*

To the developers: great job on providing divers an inexpensive method of keeping their logs up to date across multiple platforms. The existing functions meet my basic diving needs, however there are several suggestions that I think would be very benificial, which I assume you all may or may not have heard already.

Certification tracker: It would be amazing to have a function where we could quickly look at our records of past diving certifications, instead of divers having to carry a physical copy of their diver ID card everywhere they go. Please consider this!

Uploading media via mobile device: this would be an absolute killer feature if you all could incorporate it. Even if it’s just the ability to upload a few photos or a quick clip to a specific dive. It would allow divers to keep a memory jogger of where they went diving and with whom.

Syncing functions: I was fairly confused the first time I used the syncing functions via the desktop and mobile app, but eventually figured it out. However, I could see someone making the mistake of syncing from the cloud to their mobile device when in fact they want to do the opposite (mobile to the cloud, especially after manually logging dives on the mobile app during the time they were out of cellular data range). To prevent any confusion, I would recommend renaming the syncing functions so they are a bit more clearer to the lowest common denominator.

PDF print out clarity: not sure if this is just my computer or a function you could tweak in your software, but the pdf print out was slightly blurry. I could see large pixels when I attempted to print my current logbook.

Other than that, keep up the good work! I’ll definitely be using this app to log my future dives.

### 5/5 — Great App + Great Support!

*2018-07-29, version 2.1.1*

I’ve loaded ~ 75 dives from years ago and then started adding dives from my dive computer. I particularly wanted to be able to input my gas usage information as my DC does not have air integration (you can enter your gas usage, and it will calculate your SAC). Also, customer support is awesome!

### 4/5 — Impressive Profile Charts

*2017-10-19, version 1.2.1*

While not as flashy in terms of equipment tracking as other options, I really like the data-rich charts.

Easily imported my log data from another popular logging app after exporting as XML.

Not sure I'll give up that flashy closed source app, but will definitely play with this one too. 

Seamless integration across Mac, Windows, Linux, Android, and iOS. 

Nicely done!

### 5/5 — All my dive buddies can finally get it

*2016-10-27, version 1.1.1*

I have been singing the praises of this great app since I started testing it. I love the open source desktop app and this was the only thing that kept it from being great. 

This app lets me view and edit my saved dives via the subsurface cloud. Nothing but wonderful.

### 5/5 — Best dive log software comes to IOS

*2016-09-10, version 1.1*

Subsurface is an excellent dive log and dive planning software. This IOS version allows you to view your log, or manually add dives.  For planning and downloading new dives you'll need to use the Windows/Mac/Linux app but this mobile version works as a great way to carry around your log without printing.

## Most critical reviews (10 lowest-rated)

### 1/5 — Absolute garbage

*2026-07-08, version 6.0.5581*

Looks like was developed in ‘95 and extremely buggy. I can’t imagine why anyone would use this

### 1/5 — Don’t

*2026-03-12, version 6.0.5504*

Wanted to make it work but wasted too much time. Randomly changed dive dates of all dives. Manually corrected only to have them changed again. No support. Not ready for prime time. Look elsewhere.

### 1/5 — The most convoluted, frustrating app I’ve ever used

*2025-10-06, version 6.0.5436*

Seems there’s no really good apps to log dives, you’d be better off using a toaster to log your dives than this app. I’ve tried to log the same dive 3 times the exact same way and each time it gets the details wrong in a completely different way. It will just change the time, depth, duration, weight etc for no reason by a little bit of a lot. It’s like it’s a prank app.

### 1/5 — Save yourself the trouble

*2024-03-07, version 6.0.5031*

Built to interface with a computer. If you are entering manually stay on paper and save time and hassle. Clunky and confusing UI. Too often get into screens and can’t figure out how to exit. And the video tutorial so full of ads that huge time wasted

### 1/5 — Non starter

*2021-05-31, version 3.2.1*

Looking to replace MySSI but this app can’t connect to a Mares Smart Air (with bluelink adaptor) despite being a supported dive computer

### 1/5 — Not what I expected

*2020-06-30, version 3.0.9*

I’ve been using this app for a while now, just logged back in to log my weekends diving and I no longer have ANY dives logged. All my information is missing, not happy at all with this!

### 1/5 — Save support broken

*2017-07-09, version 1.2.1*

This review is for this version only. Cloud saving is broken, preventing the entering of new dives or modifying existing. It is also far too easy for an inadvertent swipe to lose all notes in progress prior to "saving". The note field does not scroll, preventing the creation/editing of longer notes

### 2/5 — Suunto ocean

*2025-08-25, version 6.0.5414*

Not compatible with Suunto ocean still..
UI is uhh quite outdated and clunky but there is a dark mode option

### 2/5 — Extremely difficult to use

*2021-02-12, version 3.1.2*

This seems to be a random number generator rather than a dive log! After carefully typing in the details of each dive the app will overwrite with whatever it feels like! Takes about 5 goes for each dive to finally convince the app that I really did want the data I had entered.

### 3/5 — Decent but can’t read Genesis Centauri

*2022-10-18, version 3.4.7*

Good logging capabilities but does not detect Genesis Centauri or the Deep6 Excusion despite being in the list. By comparison Dive Log had no problems detecting and downloading these devices.  Looks to be an example of you get what you pay for.

### 5/5 — Awesome free dive log

*2026-05-19, version 6.0.5581*

For a free dive log app this thing is pretty sweet! The UI is not the prettiest thing you’ll ever see, but what matters is the data and content - and this app does all of that well! 
I first download the Mac app on my MacBook and I find that it’s easier for me to upload all my dives directly to my MacBook first, and then sync them with the cloud. Once you do that they all become visible here in the mobile app for easy viewing and editing. 
I hope the developers keep this app current because it’s great!

### 5/5 — Best dive logger hands down

*2025-08-11, version 6.0.5414*

I use this on my MacBook and iPhone and find it preferable to the SSI and Shearwater apps.

### 5/5 — Most versatile Dive log

*2024-11-14, version 6.0.5276*

I have used Subsurface for years and it has every feature I would ever need.  I can’t specify what is the best feature because it has many.  The top 2 are first it’s compatible with most dive computers and second it works on most pc OS and mobile devices.

### 5/5 — Amazing dive log!

*2022-04-27, version 3.4.3*

Thank you for such a great FLOSS dive log. You’re the best ❤️

### 5/5 — Still the best

*2021-11-24, version 3.4.1*

Love Subsurface and have for many years. Subsurface is the cleanest easiest way to log your dives, with lots of robust features including cloud sync.
The mobile client is great but there are as always features I would like to see someday.
 
I would love to: 
- Be able to add images to the timeline profile like desktop client. These days they are cloud synced one way or another, or even taken on phone, so readily available.
- Be able to quickly/easily capture start/end gps locks. I know there is some function there but it’s not easy imo.
- add dive site based on GPS information tagged to image (this how I started reliable grabbing location when traveling).
- easy composite image of dive info on picture or shoeing pictures on time line for social media and to be album cover.
- a way for a buddy to digitally counter sign the log. Most divers don’t care but anyone doing professionally stuff has logging requirements.

### 5/5 — Great free dive log software

*2021-04-09, version 3.2.1*

I got this software after many problems getting the software from my dive computer to sync.  I use a PC to import dives (my dive computer didn't do Bluetooth)and the iPad to view.   Software captures a lot of info.   After some difficulties getting everything to sync, the developer quickly helped me resolve issues.   So much nicer than a paper dive log!

### 5/5 — Very Impressed +++

*2020-08-07, version 3.0.11*

Just starting out using this program and already I’m impressed. Dirk personally resolved an issue I was having! I finally can see all my dives from manuel inputs and 2 dive computers in one app! Thank you again and I can’t wait to fully explore your APP!

### 5/5 — Best overall dive log app out there...

*2019-10-28, version 2.1.6*

Open source app that is compatible across multiple platforms and provides FREE cloud storage to support synchronization across all of your platforms. Plays well with just about every dive computer out there.
I was also able to import previous dives from a OEM application 
Super support available via forum.

### 5/5 — Wow

*2019-02-16, version 2.1.6*

I came across the desktop version of Subsurface when I was looking for an alternative to the Cressi software. I had all of my dives pulled down from our computers in a snap. Moved my notes over and synced with the cloud. Instantly updating my iPhone with all of my log details. LOVE this app. Can’t believe it’s free!

### 5/5 — Best dive log ap

*2018-09-16, version 2.1.1*

This is the best dive log app.  Ive tried several including paid apps and was so happy to finally find this one.  It does everything I want.  Able to Download complete dive profiles off the dive computer, mark dive sites with gps.  Lots of cool features.  Ap is still in development and takes a little fiddling to get used to but works great for me.  Developers are accessible to help with troubles or questions.  Recommend to all my dive friends!
