And subsequently will not let me connect to my watch. This all comes right after the latest iOS update. I hope this is just a bug that will be fixed soon. ### 1/5 — After unpairing my Atmos watch one, I can’t pair again *2021-11-27, version 2.5.7* This app seemed great at face value, but after unpairing my watch once, I cannot repair it again with the app. This is a huge bummer… hoping support gets back to me. ### 1/5 — Cannot Pair *2021-05-20, version 2.5.2* Unable to pair phone and dive computer. The connect button is shown, but when I touch connect nothing happens. Totally useless. ### 1/5 — Won’t sync with my phone *2021-02-08, version 2.2.1* My ios app wont sync with the watch anymore when my friend has no problem with the android app. Please fix it asap ### 1/5 — Watch won’t sync now *2020-12-28, version 2.0.5* My mission one watch won’t sync ### 1/5 — Won’t pair !! *2020-10-02, version 2.0.4* Can’t even set the time right since it won’t pair 😡 ### 1/5 — App. *2020-09-28, version 2.0.4* The app will no longer connect with the device to sync logs after the latest IOS updates. ## Most critical reviews (10 lowest-rated) ### 1/5 — App freezes constantly *2025-11-02, version 4.1* App not very stable ### 1/5 — Doesn’t work *2025-03-18, version 4.0.2* Absolutely does not pair to device The device connects but will not pair, update, transfer data. Pointless ### 1/5 — Fine when it works *2025-03-08, version 4.0.2* This app is fine when it works, but I haven’t been able to connect my device to it since updating the app. Pretty disappointing! ### 1/5 — Great watch, awful software *2024-12-24, version 4.0.0* The app requires internet in order to even view your logs. Makes no sense as they can be saved offline. Newest update now doesn’t connect to my watch anymore suddenly with a timeout error. Perhaps ATMOS servers are down but seems very unnecessary to sync to servers before syncing locally to the phone ### 1/5 — I’d give it no stars, if I could *2024-05-06, version 3.5.1* I loved this app, for the first few dive trips. Now it won’t connect and it won’t sync. The app is worthless. I love how the watch operates in the water. How disappointing to not be able to have the dive log sync now. ### 1/5 — Won’t connect to watch *2024-03-28* Started out really great but can no longer get app to connect with the app. If I try to connect in the Home Screen, the app crashes. If I connect through the profile it sees the watch but won’t allow me to hit the connect button. Had this issue for months and still can’t get it to work. ### 1/5 — App doesn’t work. Computer screen is practically unreadable. Don’t waste your money on Atmos. *2024-02-25, version 3.4.0* App doesn’t work. Computer screen is practically unreadable. Don’t waste your money on Atmos. ### 1/5 — Disappointing *2023-08-31, version 3.1.5* In theory the app is very nice but when I go to change things like my personal data or syncing the app completely shuts down. ### 1/5 — Can’t connect *2022-12-03, version 3.0.8* App is trash, can’t connect to the watch ever, can’t even press the button. When it somehow finally reads the watch it just says connecting for ages and does nothing. ### 1/5 — Will not pair with IPhone *2022-09-28, version 3.0.7* Very annoying. Computer it self is very intuitive but iOS connection is not. ## Most praised reviews (9 highest-rated) ### 5/5 — Works exactly as expected *2022-05-31, version 3.0.0* I’ve had no issues, the app does what it’s meant to. Logging dives is easy, everything looks nice. Syncing with the dive computer works well every time. ### 4/5 — Good App, but room for improvement *2022-06-16, version 3.0.1* The App works well with my Mission One. I’ve had no issues syncing dives. However, it’d be great if there was an “offline” mode that didn’t rely on internet connectivity. I’d also like the ability to manually enter a dive site name after the fact beyond what you can select from the database. ### 3/5 — Stops pairing *2025-01-07, version 4.0.1* Have to unpair and pair device all the sudden ### 3/5 — following update, app crashes, and will not open *2024-01-22, version 3.3.0* apparently, after the update to your app that was made last week, the app is now unstable and crashes every time I open it on the iPhone ### 3/5 — Great app but funky *2021-04-12, version 2.5.1* Everything works. But the SAC calculation seems off. Please fix! ### 3/5 — Great Super Basic App *2021-01-25, version 2.2.1* Love that my dive downloads to the app but I cannot make any changes such as psi in and out, water temp, location, etc. my husband has Android and he makes these changes with no issues. Perhaps a bug? ### 2/5 — Hard to enter dive logs *2024-12-31* Tried to enter previous dives onto this in order to have everything in one place going forward, but more than half the dive sites easily found on PADI aren’t listed when searched, and app crashes and loses data frequently. Almost unusable for entering previous dives ### 2/5 — Used to be good but no more *2024-05-06, version 3.5.1* The pairing is very finicky and now it doesn’t push notifications of my iMessages to the watch anymore. But it’d still push other notifications to my watch. So strange and unstable ### 2/5 — Poor app *2021-09-16, version 2.5.5* App no longer connect to watch… can’t log any dives --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
