Pointless ### 1/5 — Fine when it works *2025-03-08* 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! ### 3/5 — Stops pairing *2025-01-07, version 4.0.1* Have to unpair and pair device all the sudden ### 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 ### 1/5 — Great watch, awful software *2024-12-24* 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 ### 2/5 — Used to be good but no more *2024-05-06* 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 ### 1/5 — I’d give it no stars, if I could *2024-05-06* 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. ## Frequently asked questions about ATMOS ### What does the ATMOS app do? The ATMOS app serves as a companion for Mission One, Mission2, and Mission3 dive computers.
