Review summary

Users praise the ATMOS dive watch hardware for its intuitive design and dive functionalities. However, the companion Android app receives multiple complaints about frequent Bluetooth pairing failures, slow and unreliable syncing, and reliance on internet connectivity which limits offline usability. The app also suffers from bugs like crashes and permission issues, and lacks critical features such as dive log editing and social sharing. Users desire better stability and more comprehensive app features to complement the generally well-regarded dive watch hardware.

Pros

The dive watch hardware itself is generally appreciated for its user-friendly graphical interface and functionality.
The app allows synchronization of dive data between the watch and the phone, which works well for some users.
Customer service seems responsive, as demonstrated by the watch replacement in a hardware glitch case.
The app and watch combination supports important dive logging features for some users.
The watch functions well as a dive computer compared to competitors in the price range.

Cons

The app has persistent issues with Bluetooth pairing and syncing, causing frequent connection problems between the watch and phone.
The app requires internet connectivity to function properly, making it unusable during offline dive scenarios like diving safaris.
Numerous bugs affect the app's usability, including crashes, freezes on loading screens, and slow or failed synchronization.
Permissions requests are confusing or excessive, for example location permission errors despite granted permissions, causing user frustration.
The app lacks important features such as dive log editing, social sharing, dive site tagging, and customizable notifications, limiting its usefulness for divers.

2025-01-08	Da*****	App not recording heart rate info collected by watch (Mission 2) since the latest update (please patch this). Otherwise, it's a great dive watch!

2024-12-27	J *****	Keeps crashing (when working) otherwise stays at the loading screen locked up.

2024-10-05	Na*****	The idea is good, but there's plenty of bugs and weirdness which make me dislike using the app. Confirm your google account twice each time you open the app? Surface interval never stops counting? Can't tag/name a dive site in the app and have it appear on the device for later reuse? Device showing dives even when deleted, but the app does not? Device: Mission 2. Needs some work for 5 star.

2024-07-20	Wi*****	Won't pair with the phone even if it detects it. It will work when you restart your phone and watch.

2023-08-28	TN*****	v3.1.5 \| Mission 2: I can't access 'device dive sites', 'tides', 'weather', 'watch face' or 'personal' menus. I get the error: "Please provide the location permission to access Bluetooth." What does that mean? Location permission is already granted. It all worked before this update. 🤬 ■ Answer to developer's reply: You didn't read my review carefully: "Location permission is already granted." Also, if I don't want notifications, why are all those permissions necessary for the app to work?

2023-08-27	Af*****	Not able to correctly sort or filter my dive list. For instance, I want to be able to sort or filter longest CWT dive or deepest CNF dive I had.

2023-07-21	An*****	Buggy sync, both with the watch and with the cloud. If you have several dives to sync, it takes from 10 minutes to half hour to sync, many sync attempts end with an error. After you have managed to sync with the watch, it takes the app ages to show your dive profile. The progress bar keeps rolling and rolling, although the log is on your phone already. Hope the devs will fix it in later versions, now this app is too buggy for everyday use. Also use the app from shearwater to compare, works fine

2023-07-19	Ae*****	The app doesn't work locally and requires internet... I'm using the M2 and the computer itself works nicely... But using it as a smartwatch for notifications wouldn't be recommended... It doesn't work 90% of the time unless you keep clearing the app's data and pair it again

2023-07-01	Sa*****	Love it However Can you update the app & add high & low tides for locations like you do with the sunset/Sunrise feature Kind regards .... Hey team Used to be able to just turn watch on & get on with it ... now to have the correct time & date, it has to go through the syncing process everytime Boring 😔

2023-01-20	Gr*****	Does not even open without Internet. Does not store dive logs on the device. Absolutely unusable during diving safaris because, surprise, there is no Internet in the middle of the ocean. And good luck using the App in the roaming without buying a SIM card. Whoever programmed it obviously never used it themselve. Watch itself is good though.
